AUSCERT Week in Review for 20th April 2018

AUSCERT Week in Review for 20th April 2018 Greetings,   Right off the back of Microsoft’s patch Tuesday and Red Hat’s RHEL 7.5 updates, this week we have Oracle’s quarterly Critical Patch Updates and a slew of Cisco Advisories and Alerts – phew!   Bonus: A short video from CrikeyCon 2018 (a community-run information security conference in Brisbane) https://www.youtube.com/watch?v=VeOM-FxXOzY Here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: Title: Russian State-Sponsored Cyber Actors Targeting Network Infrastructure Devices Date Published: Mon, 16th April 2018 Author: US-CERT Excerpt: “Since 2015, the U.S. Government received information from multiple sources—including private and public sector cybersecurity research organizations and allies—that cyber actors are exploiting large numbers of enterprise-class and SOHO/residential routers and switches worldwide. The U.S. Government assesses that cyber actors supported by the Russian government carried out this worldwide campaign. These operations enable espionage and intellectual property theft that supports the Russian Federation’s national security and economic goals.” —– Title: Why is the kernel community replacing iptables with BPF? Date Published: Tue, 17th April 2018 Author: Thomas Graf Excerpt: “Facebook has presented exciting work on BPF/XDP based load-balancing to replace IPVS that also includes DDoS mitigation logic. While IPVS is a tempting next step compared to iptables, Facebook is already migrating away from IPVS to BPF after seeing roughly a 10x improvement in performance.” —– Title: FDA Wants Medical Devices to Have Mandatory Built-In Update Mechanisms Date Published: Thur, 19th April 2018 Author: Catalin Cimpanu Excerpt: “An FDA document released this week reveals several of the FDA’s plans, including the desire to force device makers to include mandatory update systems inside products for the purpose of delivering critical security patches.” “In addition, the FDA also plans to force device makers to create a document called “Software Bill of Materials” that will be provided for each medical device and will include software-related details for each product.” —–  Title: Microsoft Debuts Azure Sphere for IoT Security From Chip to Cloud Date Published: Mon, 16th April 2018Author: Rob Marvin Excerpt: “Smith said Microsoft is making the Azure Sphere Security Service compatible not only with Azure, but with other cloud infrastructure providers such as Amazon Web Services (AWS), Google Cloud, IBM, Oracle, and others. The company is doing this for the same reason it’s releasing a Linux-based OS: making sure billions of IoT devices are secure.” —–   Here are this week’s noteworthy security bulletins:   1) ESB-2018.1182 – [Appliance] Abbott Laboratories Defibrillator: Multiple vulnerabilities Abbott has produced firmware updates to help mitigate identified vulnerabilities in their eligible ICDs and CRT-Ds that utilize radio frequency (RF) communications. A third-party security research firm has verified the new firmware updates mitigate the identified vulnerabilities.   2) ESB-2018.1232 – [Win][UNIX/Linux] Drupal core: Cross-site scripting – Remote with user interaction   CKEditor, a third-party JavaScript library included in Drupal core, has fixed a cross-site scripting (XSS) vulnerability. 3) ESB-2018.1229 – [SUSE] Linux kernel: Multiple vulnerabilities The SUSE Linux Enterprise 12 SP3 Realtime kernel was updated to 4.4.120 to receive various security and bugfixes.   4) ASB-2018.0077 – [Win][UNIX/Linux] Oracle Database Server: Multiple vulnerabilities Difficult to exploit vulnerability allows low privileged attacker having Create Session, Create Procedure privilege with network access via multiple protocols to compromise Java VM.  While the vulnerability is in Java VM, attacks may significantly impact additional products. 5) ESB-2018.1142 – [Win][UNIX/Linux][BSD][Debian] perl: Execute arbitrary code/commands – Remote with user interaction GwanYeong Kim reported that ‘pack()’ could cause a heap buffer write overflow with a large item count. Stay safe, stay patched and have a good weekend!   Charelle.

AUSCERT Week in Review for 13th April 2018

AUSCERT Week in Review for 13th April 2018 Greetings, Happy Friday the 13th all! Well, Cisco’s Smart Install protocol vulnerability that potentially leads to Remote denial of service and code execution attacks, now has a publicly available exploit. So get fixing it! AUSCERT members exposed to this vulnerability will receive MSINs addressing the issue.  Microsoft had 5 security updates addressing it’s browsers, Windows OS and Office products. None had known publicly available exploits at the time. Then, there’s the lighter side of things, like PUBG ransomware (PUBG doesn’t stand for pub games unfortunately). It requires victims to play Player Unknown’s Battleground for 1 hour to decrypt it, but wait, there’s more! Read on. Here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: Title: Researchers discovered several flaws that expose electrical substations to hack Date Published: 12/04/2018 Author: Pierluigi Paganini, Security Affairs Excerpt: “By exploiting these vulnerabilities, an attacker is able to change the configuration of power-system protection relay which can lead to disruption of the power equipment protection function (and potentially to an accident) or customer curtailment.”   The most severe vulnerability (rated high severity), tracked as CVE-2018-4840 can be exploited by a remote and unauthenticated attacker to modify the device’s configuration and overwrite access passwords.   “The device engineering mechanism allows an unauthenticated remote user to upload a modified device configuration overwriting access authorization passwords. ” reads the security advisory published by Siemens.   The second flaw, tracked as CVE-2018-4839, is a medium severity issue that could be exploited by a local or network attacker to recover the access authorization password by intercepting network traffic or obtaining data from the targeted device. Once the attacker has obtained the password he can use it to gain complete access to a device.” —– Title: Health holds crown as the most breached sector in Australia Date Published: 11/04/2018 Author: Asha McLean, ZDNet Excerpt: “The Quarterly Statistics Report: January 2018-March 2018 revealed that health service providers accounted for 15 breaches; legal, accounting, and management services suffered 10; finance, including superannuation, reported eight breaches; education suffered six; and charities four.   The NDB scheme requires agencies and organisations in Australia that are covered by the Privacy Act 1988 to notify individuals whose personal information is involved in a data breach that is likely to result in “serious harm” as soon as practicable after becoming aware of a breach.   According to the OAIC report [PDF], 73 percent of eligible data breaches reported involved the personal information of less than 100 individuals, with just over half of the notifications involving the personal information of between one and nine individuals.” —– Title: Barracuda Threat Spotlight: New URL File Outbreak Could be a Ransomware Attempt Date Published: 10/04/2018 Author: Jonathan Tanner, Barracuda Excerpt: “Multiple downloaders, malicious apps that download further malicious apps to infected devices, have made it onto the Google Play Store. The downloaders are capable of downloading further apps that pose as system apps, some of which are capable of stealing Facebook login credentials. To do so, the malicious apps use social engineering tactics to trick victims into giving them up.” —– Title: PUBG Ransomware Decrypts Your Files If You Play PlayerUnknown’s Battlegrounds Date Published: 09/04/2018 Author: Lawrence Abrams, Bleeping Computer Excerpt: “Once a user plays the game and the process is detected, the ransomware will automatically decrypt the victim’s files.  This ransomware is not too advanced as it only looks for the process name and does not check for other information to confirm that the game is actually being played. That means you can simply run any executable called TslGame.exe and it will decrypt the files. This is not the first time a joke ransomware has been created that requires you to play a game before files will be encrypted. In 2017, MalwareHunterTeam also found RensenWare, which required you to play the TH12 Game and score .2 billion points in order to get recover your files.” —- Title: Major uptick in mobile phishing URL click rate Date Published: 10/04/2018 Author: HelpNet Security Excerpt: “Phishing attacks are particularly effective on mobile devices because hidden email headers and URLs make it easy to spoof email addresses and websites while new vectors, including SMS and messaging apps, enable attackers to make their campaigns personal. “It’s critical for enterprises to realize that when it comes to mobile devices, email is not the only phishing attack vector,” said Cockerill. “Attackers now take advantage of SMS, as well as some of today’s most popular and highly used social media apps and messaging platforms, such as WhatsApp, Facebook Messenger, and Instagram, as a means of phishing. Security professionals who overlook these new routes of attack put their organizations at risk.”” Here are this week’s noteworthy security bulletins: 1) ESB-2018.1122 – [Cisco] Cisco IOS and IOS XE: Multiple vulnerabilities Leading the way is this advisory from Cisco addressing multiple vulnerabilities in its Smart Install Client and related protocol that can be exploited to result in Remote code execution or denial of service. An exploit is publicly available. Immediate patching is highly advised. 2) ESB-2018.1080 – [Win][Linux][OSX] Adobe Flash Player: Multiple vulnerabilities More code execution vulnerabilities fixed in Adobe Flash Player. 3) ASB-2018.0075.2 – UPDATE [Win] Microsoft Windows: Multiple vulnerabilities This update for Microsoft Windows addressed a number of vulnerabilities including a two-year old privilege escalation vulnerability that affects Windows 10 as well. Stay safe, stay patched, stay cool and have a good weekend! Nicholas

AUSCERT Week in Review for 6th April 2018

AUSCERT Week in Review for 6th April 2018 AUSCERT Week in Review6 April 2018 Greetings, As Friday the 6th of April closes, kernel updates and Spectre Meltdown patches looks to be an ongoing source of bulletins.  On the note of patches, it seems that Easter was the time of giving, with PSIRTs providing all their Easter gifts over the long weekend, resulting in a solid volume of bulletins this week. At least the onslaught of patches was expected, of sorts, and an impact that is expected loses most of its sting.Perhaps this is the same for EU’s GDPR and the expected impact of businesses dealing with Europe.  It could be that the implementation of the Privacy Act Amendment here in Australia may have provided the impetus for concerned companies about assessing their processes and risks in using and storing private information. As for news, here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: ——- Title:   Intel admits a load of its CPUs have Spectre v2 flaw that can’t be fixedURL:    http://www.theregister.co.uk/2018/04/04/intel_spectre_microcode_updates/Date:   4th April 2018Author: Simon Sharwood Excerpt:“Intel has issued fresh “microcode revision guidance” that reveals it won’t address the Meltdown and Spectre design flaws in all of its vulnerable processors – in some cases because it’s too tricky to remove the Spectre v2 class of vulnerabilities. The new guidance, issued April 2, adds a “stopped” status to Intel’s “production status” category in its array of available Meltdown and Spectre security updates. “Stopped” indicates there will be no microcode patch to kill off Meltdown and Spectre.” ——- Title:  The EU’s General Data Protection Regulation, explainedURL:    https://www.cnet.com/how-to/gdpr-eu-general-data-protection-regulation-explained/Date:   4th April 2018Author: Justin Jaffe Excerpt:“The European Union is raising the standards — and stakes — of personal data privacy. In May 2018, the General Data Protection Regulation (GDPR), will take effect and change the rules of the road for companies that collect, store or process large amounts of user information. That means you, Facebook.” ——- Title:   GDPR is Not a Ticking Timebomb for Huge FinesURL:     https://www.infosecurity-magazine.com/opinions/gdpr-timebomb-huge-fines/Date:    5th April 2018Author:  Jason Coggins Excerpt:“One of the biggest misconceptions that organizations have is that if an incident occurs then you will automatically be faced with a fine. I was reading a blog written by Elizabeth Denham of the ICO recently, and she made the point that fines are a last resort. The point of GDPR is to ensure fair and proportionate (proportionate being the operative word here) action is taken against those that fail to meet the agreed standards. There are warnings, recommendations and finally fines for those worst-case scenarios.” ——- Title:  Facebook: It wasn’t 50M hit by Cambridge Analytica breach, but rather 87MURL:    https://arstechnica.com/tech-policy/2018/04/facebook-now-says-87-million-people-affected-by-cambridge-analytica-breach/Date:   5th April 2018Author: Cyrus Farivar and Sean Gallagher Excerpt:“At the end of a lengthy piece, authored by Facebook CTO Mike Schroepfer, the company said simply: “In total, we believe the Facebook information of up to 87 million people—mostly in the US—may have been improperly shared with Cambridge Analytica.” Last month, the British data analytics contractor which worked with Donald Trump’s presidential campaign retained private data from 50 million Facebook users despite claiming to have deleted it. The scandal has spawned numerous lawsuits, and it has put significant pressure on Cambridge Analytica and Facebook.” ——- Title:  CertUtil.exe Could Allow Attackers To Download Malware While Bypassing AVURL:    https://www.bleepingcomputer.com/news/security/certutilexe-could-allow-attackers-to-download-malware-while-bypassing-av/Date:   4th April 2018Author: Lawrence Abrams Excerpt:“Windows has a built-in program called CertUtil, which can  be used to manage certificates in Windows. Using this program you can install, backup, delete, manage, and perform various functions related to certificates and certificate stores in Windows. One of the features of CertUtil is the ability to download a certificate, or any other file for that matter, from a remote URL and save it as a local file using the syntax “certutil.exe -urlcache -split -f [URL] output.file”.”——- Title:  Researchers Hijack Over 2,000 Subdomains From Legitimate Sites in CloudFront ExperimentURL:    https://www.bleepingcomputer.com/news/security/researchers-hijack-over-2-000-subdomains-from-legitimate-sites-in-cloudfront-experiment/Date:   5th April 2018Author: Catalin Cimpanu Excerpt:“Experts found that CloudFront’s CDN routing mechanism that linked a site’s domain and subdomains to a specific server contained a flaw that allowed attackers to point misconfigured subdomains to their own endpoint instead, effectively hijacking the subdomain from legitimate CloudFront users.” ——- Here are this week’s noteworthy security bulletins (in no particular order): 1.    ASB-2018.0066 – [Win] Microsoft Windows: Administrator compromise – Existing account https://portal.auscert.org.au/bulletins/60506 Windows 7 and 2008 server ulnerable to a Windows Kernel Elevation of Privilege Vulnerability. 2.    ESB-2018.0999 – [Win] Microsoft Malware Protection Engine: Administrator compromise – Remote with user interactionhttps://portal.auscert.org.au/bulletins/60678 A remote code execution vulnerability patched in the Microsoft Malware Protection Engine. 3.    ESB-2018.0967 – [Mac] High Sierra: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/60546 A malicious application may be able to execute arbitrary code with kernel privileges. 4.    ESB-2018.1040 – [Appliance] Moxa MXview: Access privileged data – Remote/unauthenticatedhttps://portal.auscert.org.au/bulletins/60850 The private key of the web server is able to be read and accessed via an HTTP GET request. 5.    ESB-2018.1042 – [RedHat] python-paramiko: Execute arbitrary code/commands – Remote/unauthenticatedhttps://portal.auscert.org.au/bulletins/60862 A customized SSH client can simply skip the authentication step. — Wishing you the best from AUSCERT and hope to see you safe next week,Geoffroy

AUSCERT Week in Review for 29th March 2018

AUSCERT Week in Review for 29th March 2018 AUSCERT Week in Review29 March 2018 Greetings, As Thursday the 29th of March closes, there are a few things on the AUSCERT’s team’s mind.First and foremost is the two (2) days of AUSCERT Conference at the Gold Coast on Thursday May 30, and Friday June 1st.  Equally important is that the registration for the AUSCERT tutorials that precede the conference is out and remember that tutorials are complimentary for anyone who holds a Full Conference Registration. You can find further information on each of the tutorials via https://conference.auscert.org.au/conference-program/  The conference is a big event but there is also another big event at the Gold Coast which may draw unwanted interest from spammers. This is the GC2018 Commonwealth Games.  So making your users aware that spammers may make the most of events and craft emails in ways that entice them to open attachments or follow link, could be worth the while. And to make a difference, on the first hour of the last day of the week, instead of the last hour of the last day of the week, Drupal Core has a patch available where by they expect the PoC to come out “hours or days” after the disclosure.  So I do hope you got the SMS from AUSCERT’s Bulletin service this morning.   As for news, here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: ——- Title:  Drupal Fixes Drupalgeddon2 Security Flaw That Allows Hackers to Take Over SitesURL:    https://www.bleepingcomputer.com/news/security/drupal-fixes-drupalgeddon2-security-flaw-that-allows-hackers-to-take-over-sites/Date:   March 28, 2018Author: Catalin Cimpanu Excerpt:“The Drupal CMS team has fixed a highly critical security flaw that allows hackers to take over a site just by accessing an URL.Drupal site owners should immediately —and we mean right now— update their sites to Drupal 7.58 or Drupal 8.5.1, depending on the version they’re running.The Drupal team pre-announced today’s patches last week when it said “exploits might be developed within hours or days” after today’s disclosure” ——- Title:  Don’t get hacked during the Games  URL:    https://www.technologydecisions.com.au/content/security/news/don-t-get-hacked-during-the-games-634148475Date:   March 23, 2018 Author: Technology Decisions Excerpt:“It is expected that the Gold Coast Commonwealth Games will attract high levels of cybercrime, with businesses urged to stay alert for the possibility…Potential attacks to be aware of during the 2018 Commonwealth Games include: o hacks through public Wi-Fi hotspots that will be available throughout the Games; o email-based spear phishing campaigns that trick people into divulging personal information or clicking on links that release malware into their systems; o hacked social media and business websites; o point-of-sale attacks that let cybercriminals obtain credit card details; o ransomware attacks that prey on the time-sensitive nature of Games-related activities to force victims to pay higher ransoms, fast; o fraudulent invoices and payment details.”“——- Title:  In-Browser Cryptojacking Is Getting Harder to DetectURL:    https://www.bleepingcomputer.com/news/security/in-browser-cryptojacking-is-getting-harder-to-detect/Date:   March 27, 2018Author: Catalin Cimpanu Excerpt:“Cyber-criminals aren’t stupid. If you find a way to block their code, they’re going to find a way to around your block.That’s how it’s been for decades in the antivirus business, and this is exactly what’s happening right now on the in-browser cryptocurrency mining (cryptojacking) scene…” ——- Title:  Intel CPUs Vulnerable to New ‘BranchScope’ AttackURL:    https://www.securityweek.com/intel-cpus-vulnerable-new-branchscope-attackDate:   March 27, 2018 Author: Eduard Kovacs Excerpt:“Researchers have discovered a new side-channel attack method that can be launched against devices with Intel processors, and the patches released in response to the Spectre and Meltdown vulnerabilities might not prevent these types of attacks.The new attack, dubbed BranchScope, has been identified and demonstrated by a team of researchers from the College of William & Mary, University of California Riverside, Carnegie Mellon University in Qatar, and Binghamton University.” ——- Title:  Crooks infiltrate Google Play with malware in QR reading utilitiesURL:    https://nakedsecurity.sophos.com/2018/03/23/crooks-infiltrate-google-play-with-malware-lurking-in-qr-reading-utilities/Date:   March 23, 2018Author: Paul Ducklin Excerpt:“…First, the apps were, at least on the surface, what they claimed: six were QR code reading apps; one was a so-called “smart compass”.In other words, if you were just trying out apps for fun, or for a one-off purpose, you’d be inclined to judge them by their own descriptions.Second, the crooks didn’t fire up the adware part of their apps right away, lurking innocently for a few hours before unleashing a barrage of ads.Third, the adware part of each app was embedded in what looks at first sight like a standard Android programming library that was itself embedded in the app.” ——- Title:  Thousands of etcd installations are currently leaking 750MB worth of passwords, keys, and sensitive data.URL:    http://securityaffairs.co/wordpress/70611/hacking/etcd-installs-data-leak.htmlDate:   March 25, 2018Author: Pierluigi Paganini Excerpt:“Thousands of servers belonging to private businesses and organizations are leaking credentials and potentially sensitive data.It is quite easy for hackers to use the credentials to access the servers and steal sensitive data or use the machines to power cyber attacks.According to the researcher Giovanni Collazo, querying the popular Shodan search engine he found almost 2,300 servers exposed online that were running etcd, which is a distributed key value store that provides a reliable way to store data across a cluster of machines.” ——- Title:  Facebook Collected Call and SMS Metadata From Some Users’ SmartphonesURL:    https://www.bleepingcomputer.com/news/technology/facebook-collected-call-and-sms-metadata-from-some-users-smartphones/Date:   March 24, 2018Author: Catalin Cimpanu Excerpt:“Several Facebook users who downloaded an archive of their Facebook data in the wake of the Facebook-Cambridge Analytica scandal discovered this week that the social network’s mobile applications have been recording —in some cases— much more information than most people were expecting. Logged information includes data on all phone calls made on the phone, the start time o each call, its duration, and the contact’s name. The Facebook app did not log phone calls to and from numbers not saved in the phone’s address book.” ——- Here are this week’s noteworthy security bulletins (in no particular order): 1.    ESB-2018.0844 – [SUSE] kernel: Multiple vulnerabilities https://portal.auscert.org.au/bulletins/60038 The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.120 to receive various security and bugfixes including executing code. 2.    ESB-2018.0863 – [Win][UNIX/Linux][RedHat] slf4j: Execute arbitrary code/commands – Remote/unauthenticated https://portal.auscert.org.au/bulletins/60114 Deserialisation vulnerability in EventData constructor can allow for arbitrary code execution. 3.    ESB-2018.0883 – [SUSE] LibVNCServer: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/60198 Heap-based buffer overflow in rfbproto.c allowed remote servers to cause a denial of service (application crash) or possibly execute arbitrary code. 4.    ASB-2018.0063 – [Win][UNIX/Linux] Mozilla Firefox: Execute arbitrary code/commands – Remote with user interactionhttps://portal.auscert.org.au/bulletins/60158 Use-after-free in compositor results in a potentially exploitable crash. 5.    ESB-2018.0888 – [Win][UNIX/Linux][Debian][Apple iOS][Android] mupdf: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/60218 Two vulnerabilities were discovered in MuPDF, a PDF, XPS, and e-book viewer, which may result in denial of service or remote code execution. —And lastly for an even more up-and-coming event, a long four (4) day weekend looks nice, but beware little emails bearing easter eggs, and please get your Drupal site patched.   Wishing you the best from AUSCERT and hope to see you safe next week,Geoffroy

AUSCERT Week in Review for 23rd March 2018

AUSCERT Week in Review for 23rd March 2018 Greetings! This week Cambridge Analytica and Facebook were a hot topic, so all I’d like toadd is a link to this Facebook blocklist that some may find useful: https://github.com/jmdugan/blocklists/blob/master/corporations/facebook/all Here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: —- Title: ‘I made Steve Bannon’s psychological warfare tool’: meet the data war whistleblower Date Published: Sun, 18 Mar 2018 Author: Carole Cadwalladr Excerpt: “For more than a year we’ve been investigating Cambridge Analytica and its links to the Brexit Leave campaign in the UK and Team Trump in the US presidential election. Now, 28-year-old Christopher Wylie goes on the record to discuss his role in hijacking the profiles of millions of Facebook users in order to target the US electorate.” —– Title: Don’t waste the Cambridge Analytica scandal: it’s a chance to take control of our data Date Published: Fri, 23 Mar 2018 Author: Scott Ludlam Excerpt:  “The real question is whether we are ready, collectively, to draw a line under surveillance capitalism itself, and start taking back a measure of control.” —– Title: 15-Year-old Finds Flaw in Ledger Crypto Wallet Date Published: Tues, 20 Mar 2018 Author: Brian Krebs Excerpt: “Rashid discovered that a reseller of Ledger’s products could update the devices with malicious code that would lie in wait for a potential buyer to use it, and then siphon the private key and drain the user’s cryptocurrency account(s) when the user goes to use it.” —– Title: Hackers ‘led warplanes to Syrian hospital’ after targeting British surgeon’s computer Date Published: Tues, 20 Mar 2018 Author: Hayley Dixon, Aisha Majid, and Steven Swinford Excerpt: “Now the International Committee of the Red Cross is to hold a meeting with staff to warn about the dangers of hacking, using Mr Nott’s fears as an example, it is understood. “Mr Nott said on Tuesday: “The thing that gets me is that we now cannot help doctors in war zones, if somebody is watching what we are doing and blows up the hospital then that is a war crime.” —– Title: Driverless cars and the 5 ethical questions on risk, safety and trust we still need to answer Date Published: Wed, 21 Mar 2018 Author: Ariel Bogle Excerpt: “Car manufacturers need to decide whether they want to reveal how cars are ethically programmed. Or whether their customers should even have a choice.” —– Title: Nine years on, Firefox’s master password is still insecure Date Published: Tue, 20 Mar 2018 Author: John E Dunn Excerpt: “Choosing an iteration count is a matter of balancing the inconvenience you’re prepared to inflict on users when they log in against the amount of obstruction you want to put in a password cracker’s way. “The good news is you don’t have to pick one iteration count and stick to it –you can increase the iteration count over time to keep pace with improvements in hardware. “Unfortunately, Palant noticed, Firefox performs just one iteration.” —– Title: What’s your availability? DoS attacks and more Date Published: Mon, 19 Mar 2018 Author: Mike Bursell Excerpt: “The attacks we’re talking about here are those most often overlooked: attempts to degrade the availability of a service. There’s an overlap with the related discipline of resilience here, but I think that the key differentiator is that in security we’re generally talking about intentional degradation of availability, whereas resilience also covers (and maybe focuses on) unintentional degradation.” —– Here are this week’s noteworthy security bulletins: 1) Drupal: Reduced security – Unknown/unspecified Drupal have announced a highly critical security release for Drupal 7 and 8 core. 2) Mozilla Firefox, Firefox ESR: Multiple vulnerabilities An out of bounds memory write in libvorbis and libtremor has caused critical vulnerabilities in Mozilla Firefox. 3) Tenable Nessus : Increased privileges – Existing account Installing Nessus to a directory outside of the default location could potentially allow local privilege escalation. 4) Geutebruck IP Cameras: Multiple vulnerabilities Several vulnerabilities in the firmware of Geutebruck IP Cameras have been patched.

AUSCERT Week in Review for 16th March 2018

AUSCERT Week in Review for 16th March 2018 AUSCERT Week in Review16 March 2018 Greetings, Another week is coming to a close and this week brought us many new vulnerabilities to remediate and patch. Samba released fixes for two vulnerabilities, one of which is terrifying if you run Samba as your AD as unprivileged authenticated users are able to change any other users’ passwords, including admin users, over LDAP. Microsoft fixed 74 security vulnerabilities, Mozilla fixed 18 vulnerabilities with their update to Firefox 59, and Adobe also fixed vulnerabilities in Flash player (as usual), Connect and Dreamweaver CC. The first public disclosure under the new Australian Mandatory Data Breach Notification scheme has been made public, shipping company Svizter Australia, revealed that details of its employees were leaked by email. According to OAIC it has received 31 notifications in the first three weeks of the scheme being in operation. To make this post a bit less grimm: The AUSCERT2018 Cyber Security Conference program is now live!! Be sure to register as soon as possible in order to secure your spots for the Tutorials! Many of them sell out extremely quickly. The Hak5 workshop is extremely popular, Darren and Sebastian always do an amazing job. https://conference.auscert.org.au/conference-program/ Here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: Title: First data breach publicised under Australian notice scheme Date: 16/03/2018 Author: Staff Writers @ itnews Excerpt: “Svizter reveals email leak. Shipping company Svizter Australia has revealed a data breach that saw the personal information of half of its employees leaked outside the company. Yesterday it revealed that up to 60,000 emails from three accounts in finance, payroll and operations were secretly auto-forwarded to two external accounts between May 27 2017 and March 1 this year.” ———– Title: Chinese Intelligence Agencies Are Doctoring the Country’s Vulnerability Database Date: 10/03/2018 Author: Catalin Cimpanu Excerpt: “Chinese intelligence agencies are doctoring the Chinese National Vulnerabilities Database (CNNVD) to hide security flaws that government hackers might have an interest in, according to a report released on Friday by US threat intelligence firm Recorded Future. The US company says it noticed in recent months mass edits to the CNNVD website. Recorded Future says CNNVD operators have been backdating the publication dates for hundreds of vulnerabilities.” ———– Title: Necurs and Gamut Botnets Account for 97% of the Internet’s Spam Emails Date:  Catalin Cimpanu Author: 12/03/2018 Excerpt: “Just two botnets accounted for 97% of all spam emails in the last three months of 2017, according to a McAfee report released earlier today. For most of these months, Necurs has spent its time churning out “lonely girl” spam lures for adult websites, pump-and-dump schemes [1, 2], and delivering ransomware payloads. Overall, nearly two out of three spam emails sent in the last quarter of 2017 were sent from the infrastructure of this mammoth botnet.” ———– Title: One in Five Healthcare Employees Would Be Willing to Sell Sensitive Data, Reveals Survey Date: 09/03/2018 Author: David Bisson Excerpt: “A new survey reveals that nearly one in five healthcare employees would be willing to sell confidential data to an unauthorized party. According to Accenture’s 2018 Healthcare Workforce Survey on Cybersecurity, 18 percent of employees that work at healthcare providers and payers would be willing to sell sensitive data to unauthorized individuals. Respondents from providers were more open to the idea of a sale than payers at 21 percent and 12 percent, respectively. Those willing to sell would generally expect to receive between $500 and $1,000 in the process. The threat of an unauthorized data sale is not theoretical in nature, either. Almost a quarter (24 percent) of respondents know of someone in their organization who has already sold off confidential information.” ———– Title: On AMD Flaws from CTS Labs Date: 13/03/2018 Author: Kevin Beaumont Excerpt: “On AMD Flaws from CTS Labs You may have seen media reports about flaws in AMD chipsets. AMD are currently reviewing the report, as they were given less than a day notice of vulnerabilities that CTS Labs claim put lives at risk (via their website, AMDflaws.com). This is a highly unusual and reckless disclosure of security flaws.” ———– And lastly, here are this week’s noteworthy security bulletins (in no particular order): ESB-2018.0731 – ALERT [Win][UNIX/Linux] samba: Multiple vulnerabilities On a Samba 4 AD DC any authenticated user can change other users’ passwords over LDAP, including the passwords of administrative users and service accounts.

AUSCERT Week in Review for 2nd March 2018

AUSCERT Week in Review for 2nd March 2018 Greetings, This week saw Trustico revoke more than 20,000 SSL certificates it issued, gaining them the attention of the infosec community, who were quick to offer unsolicited, complimentary penetration testing services for their website. GitHub has achieved the dubious (but well-handled) honour of being the biggest DDoS recipient, taking the crown from Dyn – dealing with 1.35Tbps of traffic at its peak. This attack was made possible by a memcached UDP amplification attack. Here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: The UK and Australian Governments Are Now Monitoring Their Gov Domains on Have I Been PwnedDate Published: 02 March 2018Author: Troy HuntExcerpt: “As of now, all UK government domains are enabled for centralised monitoring by the National Cyber Security Centre (NCSC) and all Australian government domains by the Australian Cyber Security Centre (ACSC).”   ——- 23,000 HTTPS certs will be axed in next 24 hours after private keys leakDate Published: 01 March 2018Author: John LeydenExcerpt: “This is allegedly due to a security blunder in which the private keys for said certificates ended up in an email sent by Trustico. Those keys are supposed to be secret, and only held by the cert owners, and certainly not to be disclosed in messages. In the wrong hands, they can be used by malicious websites to masquerade as legit operations.” ——- Financial Cyber Threat Sharing Group PhishedDate Published: 01 March 2018Author: Brian KrebsExcerpt: “The Financial Services Information Sharing and Analysis Center (FS-ISAC), an industry forum for sharing data about critical cybersecurity threats facing the banking and finance industries, said today that a successful phishing attack on one of its employees was used to launch additional phishing attacks against FS-ISAC members.” ——- GitHub hit with largest ever DDoS attackDate Published: 02 March 2018Author: Allie CoyneExcerpt: “Developer platform Github has been hit with the most powerful distributed denial of service attack on record, managing to survive 1.35 Tbps of traffic flooded to its website relatively unscathed.” ——- Memcrashed – Major amplification attacks from UDP port 11211Date Published: 27 February 2018Author: Marek MajkowskiExcerpt: “Amplification attacks are effective, because often the response packets are much larger than the request packets. A carefully prepared technique allows an attacker with limited IP spoofing capacity (such as 1Gbps) to launch very large attacks (reaching 100s Gbps) “amplifying” the attacker’s bandwidth.” ——- Here are this week’s noteworthy security bulletins: 1) ESB-2018.0571 – ALERT [Win][UNIX/Linux][Apple iOS][Android] SAML libraries: Multiple vulnerabilitiesSAML signature generation and parsing libraries did not standardise behaviour, and thus it was possible to use comments to gain valid SAML assertions they were not authorised for. 2) ESB-2018.0538.2 – UPDATE [Win][UNIX/Linux] Drupal Core: Multiple vulnerabilitiesA number of vulnerabilities in Drupal’s core modules have been fixed, including XSS vectors. 3) ESB-2018.0603 – [Linux][Debian] freexl: Multiple vulnerabilitiesA library for manipulating Excel data is vulnerable to RCE if given a maliciously malformed document.   Stay safe, stay patched and have a good weekend!Tim

AUSCERT Week in Review for 9th February 2018

AUSCERT Week in Review for 9th February 2018 Greetings, The revolving door of information security continues, as Flash receives a patch for the 0day reported last week, while WordPress breaks auto-updating. Cisco has observed attacks against its Adaptive Security Appliance in the wild, and released a follow up patch for the RCE – noting that the first release didn’t entirely fix the problem. In non-security news, SpaceX has launched the 4th electric car to be sent into space (See: LRV-001 through 003). While they didn’t medal, their competition had a 44 year head start, so it remains impressive never the less. Here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: Title: Hackers Pounce on Cisco ASA Flaw (CVE-2018-0101)Date Published: 08/02/2018Author: Catalin CimpanuExcerpt: “Five days after details about a vulnerability in Cisco ASA software became public, hackers have now started exploiting this bug in the wild against Cisco ASA devices.” —– Title: WordPress Holds “Epic Fail Week” – Devs Break Background Updates, Ignore Zero-DayDate Published: 08/02/2018Author: Catalin CimpanuExcerpt: “A basic maintenance version released on Monday – WordPress 4.9.3 – a release meant to fix basic bugs caused huge problems for WordPress site owners by breaking the automatic update mechanism that upgrades WordPress sites in the background, without user interaction.” —– Title: How Long is Long Enough? Minimum Password Lengths by the World’s Top SitesDate Published: 06/02/2018Author: Troy HuntExcerpt: “I’ve been giving a bunch of thought to passwords lately. Here we have this absolute cornerstone of security – a paradigm that every single person with an online account understands – yet we see fundamentally different approaches to how services handle them. Some have strict complexity rules. Some have low max lengths. Some won’t let you paste a password. Some force you to regularly rotate it. It’s all over the place.” —– Title: Chrome will mark all HTTP sites ‘not secure’ from JulyDate Published: 09/02/2018Author: IT NewsExcerpt: “The company is on a long-term drive to stamp out unencrypted web connections, having begun to demote unencrypted sites in search results in 2015. Last year it started labelling HTTP login pages and credit card forms as ‘not secure’.” —– Title: Cybersecurity job fatigue affects many security professionalsDate Published: 06/02/2018Author: Jon OltsikExcerpt: “No one is talking about it, but I believe cybersecurity job fatigue is a real, growing, and troubling problem, exacerbated by the global cybersecurity skills shortage and the increasingly dangerous threat landscape. To address this, CISOs must assess the state of mind of key staff members, create work schedules to rotate personnel off the front lines, and provide the right levels of support, stress relief programs, and career counselling.” Here are this week’s noteworthy security bulletins: 1) ESB-2018.0326.2 – UPDATED ALERT [Win][Linux][Mac] Adobe Flash Player: Execute arbitrary code/commands – Remote with user interaction Flash 28.0.0.161 fixes last week’s 0day. 2) ESB-2018.0284.4 – UPDATE [Cisco] Cisco Adaptive Security Appliance: Execute arbitrary code/commands – Remote/unauthenticated Cisco has released a follow up patch for the ASA RCE, as the first was insufficient. 3) ASB-2018.0041 – [Win][UNIX/Linux] WordPress: Reduced security – Existing account WordPress’ auto-update may have just broken auto-update if it has auto-updated itself to 4.9.3. Manually update to 4.9.4 to remedy the issue. 4) ESB-2018.0404 – [Appliance] Kaspersky Secure Mail Gateway: Multiple vulnerabilities Kaspersky has patched several vulnerabilities in its Secure Mail Gateway.

AUSCERT Week in Review for 2nd February 2018

AUSCERT Week in Review for 2nd February 2018 Greetings, In pun-related security news this week, a literal cabinet was named as the source of some highly sensitive cabinet document leaks. Just goes to highlight the golden rule of security – know your assets. A 0day Flash exploit blamed on the North Koreans has been sighted targeting South Korean users. Adobe plans to have the vulnerability patched by next week, but until then turning it off is an option. Adaptive phishing kits are beginning to up their mimicry game. A newly discovered kit has been found that will download the favicon from the victim’s email domain and use that to help spoof the page. It’s all in the details. Here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: Title: Adaptive Phishing KitDate Published: 01/02/2018Author: Xavier MertensExcerpt: “Phishing kits are usually mimicking well-known big Internet players (eBay, Paypal, Amazon, Google, Apple, Microsoft…[add your preferred one here]). I found an interesting phishing kit which adapts itself to the victim. Well, more precisely, it adapts to the victim email address.” —– Title: The Cabinet Files reveal national security breaches, NBN negotiations, welfare reform plansDate Published: 31/01/2018Author: Ashlynne McGhee and Michael McKinnonExcerpt: “The documents were in two locked filing cabinets sold at an ex-government sale in Canberra. They were sold off cheaply because they were heavy and no-one could find the keys. A nifty person drilled the locks and uncovered the trove of documents inside.” —– Title: GoGet alleged ‘hacker’ revealed as infosec researcher Nik CubrilovicDate Published: 31/01/2018Author: Allie CoyneExcerpt: “According to the Illawarra Mercury, Cubrilovic had informed GoGet of vulnerabilities in its fleet booking system in 2016, for which GoGet rewarded him by waiving money owed on his account. But police reportedly allege that a year later he hacked into the system when his girlfriend’s account was suspended, creating more than 30 bookings on five different vehicles and each time charging the booking to a stranger’s account.” —– Title: North Koreans deploy zero-day Adobe Flash attacksDate Published: 02/02/2018Author: Juha SaarinenExcerpt: “North Korean hackers are believed to be behind a malware campaign targeting Windows users in South Korea, using a new zero-day vulnerability in Adobe’s Flash media player. The campaign was reported by security researcher Simon Choi, who said the North Koreans have been using the Flash zero-day since the middle of November last year.” —– Title: Critical Infrastructure More Vulnerable Than Ever BeforeDate Published: 01/02/2018Author: Tara SealsExcerpt: “‘Despite numerous incidents, reports and large-scale regulatory efforts, it is alarming that, overall, industrial systems aren’t more secure than they were 10 years ago,’ said Vladimir Nazarov, head of ICS Security at PT. ‘Today, anyone can go on the internet and find vulnerable building systems, data centers, electrical substations and manufacturing equipment. ICS attacks can mean much more than just blackouts or production delays – lives may be at stake. This is why it’s so important that before even writing the first line of code, developers design-in the security mechanisms necessary to keep ICS components secure. And when these mechanisms eventually become outdated, they need to modernize them in a timely manner.'” Here are this week’s noteworthy security bulletins: 1) ASB-2018.0039 – [Win][UNIX/Linux] Mozilla Firefox: Execute arbitrary code/commands – Remote with user interaction Firefox 58.0.1 fixes some unsanitised browser UI output that could lead to an RCE. 2) ASB-2018.0038 – [Win][UNIX/Linux] Mozilla Thunderbird: Multiple vulnerabilities Thunderbird 52.6 fixes a slew of vulnerabilities, including some potential RCEs. 3) ESB-2018.0326 – [Win][Linux][Mac] Adobe Flash Player: Execute arbitrary code/commands – Remote with user interaction Shockingly, a 0day has been discovered in Flash. Patch is expected out next week, so stay safe until then! 4) ESB-2018.0317 – [Linux][RedHat] systemd: Denial of service – Existing account In its rush to init, systemd contains a race condition in automount requests which can cause a DoS for any processes who need them. Stay safe, stay patched and have a good weekend! Tim
