APCERT 2017 AGM and Conference: A Window into the CERT community

21 Nov 2017

APCERT 2017 AGM and Conference: A Window into the CERT community Introduction This year’s APCERT Annual General Meeting and conference has just concluded, being hosted by CERT-In in New Delhi, India. Each year AUSCERT sends a representative to the APCERT conference to collaborate and cooperate with the rest of the APCERT community. This year, I was lucky enough to be selected to attend. APCERT is a community of CERT and CSIRT organisations located in the Asia-Pacific area. Originally formed in 2003, its membership has now grown to 30 organisations representing 21 economies, as well as a number of supporting partner organisations. APCERT’s goals include information sharing and cooperation between its members and the public. Arriving in New Delhi This was my first visit to India, and although I had some knowledge of Indian culture and life, I was amazed to experience it first-hand. I arrived one day before the conference began, and spent the day shopping and taking in the local sights. The bustling streets, chaotic traffic, and the sheer scale of the country are a sight to see, and offer a sharp contrast to the quiet suburban life I am used to back in Brisbane. Delhi itself is a massive city, with a population that rivals that of all of Australia. The conference itself was hosted at the Ashok hotel, in Chanakyapuri, New Delhi. This five-star hotel is located in the heart of a diplomatic and government district, close to many foreign embassies, and as a result is very accommodating to foreign guests. The APCERT Community When the conference registration opened on Sunday morning, I began meeting delegates from other APCERT members. I noticed immediately that everyone was friendly, relaxed, and very welcoming. The APCERT community is small and close-knit, and for some long-time members, the conferences are just as much of a catch-up session as they are a business trip. Apparently some of AUSCERT’s staff are quite famous in the APCERT community, as I received quite a few queries regarding some of my colleagues! All of the APCERT members are working towards the same goal – to protect their economies or industry sectors from new and existing cyber threats. As we are largely government-funded or non-profit organisations, there is no pressure to create profits or sell products, and the focus is entirely on providing the best possible service to our jurisdictions. Some of the teams that participate in APCERT are quite small and do not have the resources to analyse all new threats, so collaboration amongst teams is extremely beneficial. In addition to the welcoming atmosphere among APCERT members, the hospitality and kindness shown by CERT-In was second-to-none. This year was the first time they had hosted the APCERT conference, but the experience was extremely smooth and well-thought out. During the afternoon of the first day, we were taken on a guided tour of local sights by the CERT-In staff, before being presented with a welcome dinner. Having helped run the AUSCERT conference in the past, I know how difficult and stressful it can be to run such an event, and I commend CERT-In on their performance. Conference Proceedings and Talks The conference began with updates from the various working groups within APCERT. This is a great way to share progress with other members, and some of the work presented by teams this year was extremely impressive. One such example is the TSUBAME project, which collects network traffic data from passive “sensors” situated in many networks across the Asia-Pacific region, and compiles that data into statistics that can be used to observe trends in network scans across the internet. Other talks focused on issues such as automated malware analysis, in particular the need for non-commercial options that can be used with potentially sensitive information. A talk given by Wen-Ling Lo from TWCERT/CC brought up an excellent point: many people use services such as VirusTotal or VirScan to check suspicious email attachments, but if the attachment is legitimate and contains confidential information, uploading it to a commercial company’s services could result in an information leak. TWCERT/CC are currently developing a tool that can be used by businesses and governments in Taiwan to examine files without fear that samples will be sent to external or commercial companies. AUSCERT is very impressed with their efforts and will be tracking their progress closely. Not all talks were technical, though, and an unexpectedly impactful presentation by Nurul Husna of MyCERT, the national CERT for Malaysia, described the governance and management workflows required to operate a CERT efficiently. As a technical person, it was refreshing to see a presentation on governance that made sense and showed real value. There is a real need for efficient management of resources at CERTs, due to the quick turnaround time required in order to serve our jurisdictions effectively. Additionally, some external speakers were invited to give talks at the conference. Some highlights included a talk by Akamai representative Amol Mathur on attacks that target API services directly, bypassing many of the protections that are built into front-end applications, and an overview on using machine learning to analyse malware samples by Rajesh Nikam of Quick Heal. As malware campaigns grow in both size and number, we need to move away from manual analysis in order to process as many samples as possible, making use of technologies such as machine learning to automate the process. On the final day of the conference, attendance was opened to external members of the IT industry, and the National Minister for IT & Electronics gave an address to the audience. During the conference I began to see just how large and important the IT industry in India is. With a population of over 1 billion people, internet-based solutions are essential to interacting with the government and businesses, and ensuring these interactions are protected and non-fraudulent is a problem at the forefront of the industry. The conference also served as a focus point for the local government to draw attention to emerging threats, especially as they begin to move towards more digital payment solutions. The full schedule for the APCERT Annual General Meeting and Conference may be found here: https://apcert2017.in/schedule.html The APCERT AGM Another important part of the conference is the Annual General Meeting, or AGM. At the AGM, proposals for changes and amendments to APCERT frameworks and guidelines are put forward and voted upon by members. Proposals for new working groups are also heard, and lastly, the membership of the steering committee and leadership positions are voted upon. This year, CERT-In was accepted as a new member of the steering committee, and after recognising the hard work of JPCERT/CC, MyCERT, and CERT Australia in their positions as Secretariat, Deputy Chair, and Chair respectively, the members of APCERT voted to re-appoint them to their previous positions. AUSCERT would like to thank the steering committee and leadership positions for their hard work in the past year, and congratulate them on their continued appointments. We also welcome CERT-In to the steering committee and look forward to their input in the future! Closing Remarks Attending the APCERT conference and AGM was an eye-opening experience. In the fast-moving world of Information Security, we are facing attacks in greater numbers and greater complexity. It can be difficult to sift through the vast amounts of information distributed throughout the internet, trying to find advice that is truthful, accurate, and relevant to your organisation. CERT and CSIRT organisations offer an increasingly important role in these times, distributing threat intelligence efficiently and with the goal of national/sectorial security in mind. As well, the challenges faced by each CERT are often similar, and there is great value in being able to speak freely with other organisations that share your goals. I would like to thank all of the members, partners, and guests at the conference, for welcoming me to the APCERT community. I’ve made many new friends over the last week, and hearing other analysts describe their experiences, challenges and achievements has re-invigorated my love for information security. I hope AUSCERT can continue to provide value to other APCERT members and look forward to some new collaborations in the future.I would also like to offer a special thank-you to the staff of CERT-In, for being such hospitable hosts. My first stay in India was a great experience, and I hope to return in the future.   Anthony Vaccaroanthony@auscert.org.au

AUSCERT Week in Review for 3rd November 2017 AUSCERT Week in Review03 November 2017 Greetings, As Friday 3rd of November closes, a tally of the root compromises is more than I have seen this past year.  Let’s hope that the reason why we are indeed seeing an up tick in this type of vulnerability is only because security teams and their capabilities are indeed expanding. Well, at least this is the silver lining to be seen as this cloud of root compromise bulletins rolls over.  As for news, here’s a summary (including excerpts) of some of the more interesting stories we’ve seen this week: Title:  If your websites use WordPress, put down that coffee and upgrade to 4.8.3. Thank us laterURL:    http://www.theregister.co.uk/2017/10/31/wordpress_security_fix_4_8_3/Date:   31st October 2017Author: Iain Thomson Excerpt:“The fix addresses a flaw that can be potentially exploited by hackers to hijack and take over WordPress-powered websites, by injecting malicious SQL database commands. The core installation of WordPress is not directly affected, we’re told, rather the bug is in a security function provided by the core to plugins and themes. In other words, a bug in the core leaves plugins and themes potentially at risk of being hacked, leading to whole sites being commandeered by miscreants.” ——- Title:  Just one day after its release, iOS 11.1 hacked by security researchersURL:    http://www.zdnet.com/article/ios-11-hacked-by-security-researchers-day-after-release/Date:   2nd November 2017Author: Zack Whittaker Excerpt:“A day after iOS 11.1 was released, security researchers have already broken the software. News of the exploits came from Trend Micro’s Mobile Pwn2Own contest in Tokyo, where security researchers found two vulnerabilities in Safari, the mobile operating system’s browser. “ ——- Title:  AI will not solve your security analytics issuesURL:    https://www.csoonline.com/article/3236025/artificial-intelligence/ai-will-not-solve-your-security-analytics-issues.htmlDate:   2nd November 2017Author: Alexander Poizner Excerpt:“Managing SOC is not pretty. Constant stress due to avalanche of tickets and vast amounts of data to analyze using often underpowered and sometimes outdated tools, combined with high turnover and low morale staff. It is understandable that in such environment everybody is looking for a miracle. Any new technology that has a capability to automate an analysis and detect anomalies gets attention of operations security. With an amount of hype surrounding AI, the temptation is great to jump into early adoption.” ——- Title:  Security Think Tank: Three areas of web security challengesURL:    http://www.computerweekly.com/opinion/Security-Think-Tank-Three-areas-of-web-security-challengesDate:   1st November 2017Author: Peter Wenham Excerpt:“Very few companies these days are without a website and those websites provide a portal from the internet that the bad people can exploit to attack a company’s infrastructure including the website itself. The security challenges posed by a web presence fall into the three broad categories of legal, technical and operational. On the legal side you need to have a privacy policy identifying what personal data is collected, how that data will be used and who that data might be shared with and why. The policy should be made compliant with the General Data Protection Regulation (GDPR) for which the compliance deadline is 25 May 2018, but this will require you to track GDPR guidance as it becomes available.” ——- Title:  Facebook pledges to double its 10,000-person safety and security staff by end of 2018URL:    https://www.cnbc.com/2017/10/31/facebook-senate-testimony-doubling-security-group-to-20000-in-2018.htmlDate:   31st October 2017Author: Anita Balakrishnan     Excerpt:“Facebook, under intensifying pressure from legislators and consumers to clean up its site, is pledging to double the number of people it has working on issues related to safety and security. Colin Stretch, a vice president and general counsel at Facebook, testified before senators on Tuesday alongside executives from Twitter and Google. He told them that Facebook’s staff focused on sensitive security and community issues will grow to 20,000 by the end of next year.” ——- And lastly, here are this week’s noteworthy security bulletins (in no particular order): 1.    ESB-2017.2778 – [OSX] Apple macOS: Multiple vulnerabilities https://portal.auscert.org.au/bulletins/54342 An application may be able to execute arbitrary code with system privileges. 2.    ESB-2017.2766 – [Mobile] Apple Watch: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/54294 An application may be able to execute arbitrary code with kernel privileges. 3.    ESB-2017.2763 – [Ubuntu] kernel: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/54282 A local attacker could exploit this vulnerability to cause a denial of service (system crash) or possibly execute arbitrary code with administrative privileges. 4.    ESB-2017.2782 – [Cisco] Cisco Firepower 4100 Series Next-Generation Firewall (NGFW): Root compromise – Existing accounthttps://portal.auscert.org.au/bulletins/54358 An authenticated, remote attacker to inject arbitrary commands that could be executed with root privileges. 5.    ESB-2017.2790 – [Appliance] F5 Products: Multiple vulnerabilitieshttps://portal.auscert.org.au/bulletins/54390 An authenticated attacker may be able to cause an escalation of privileges through a crafted application that uses the fork or close system call. — Wishing you the best from AUSCERT and hope to see you next week,Geoffroy

AUSCERT Week in Review for 6th October 2017 AUSCERT Week in Review06 October 2017 Greetings, As Friday 6th of October closes, the Equifax event highlights the need to have a patch management program in your organization.  In that patch management program it is important to ensure that the risks of not patching gets transferred as high up as possible and as soon as possible. So, should you not have a patch management program in place at this moment, next Monday may be a good time to set one up.  It may be better to point the finger at best practices and frameworks for patch management now, then have the finger pointed at your staff later. The above reflection came out of one of the news articles that have capped off a solid week in bulletins, and we have included a few more articles of interest that have grabbed our attention.

AUSCERT Week in Review for 27th September 2017 AUSCERT Week in Review29th September 2017 Greetings, As Friday 29th of September comes to a close, the big news is AUSCERT is hiring https://www.seek.com.au/job/34448215 Here is our summary (including excerpts) of some of the more interesting stories we’ve seen this week: Title: Dark Web Drug Suspect Cuffed On Way to Beard ContestURL: https://www.infosecurity-magazine.com/news/dark-web-drug-suspect-cuffed-beard/Date: 28 September 2017 Author: Phil MuncasterExcerpt: “A suspected dark web drug kingpin has been arrested in the US on the way to a beard-growing contest, it has emerged. Gal Vallerius, 38, was cuffed in Atlanta International Airport at the end of August en route from his home in France to the competition in Austin, Texas. Searching his laptop, border officials apparently found hundreds of thousands of dollars in Bitcoin, a Tor browser, and PGP keys linked to an “OxyMonster”. That name is used by an administrator and senior moderator on Dream Market: a typical darknet drugs marketplace.” ——- Title: Mac High Sierra hijinks continue: Nasty apps can pull your passwordsURL: http://www.theregister.co.uk/2017/09/28/high_sierra_hijinks_continue_nasty_apps_can_pull_your_passwords/Date: 28 September 2017 Author: Shaun NicholsExcerpt: “Apple still hasn’t been able to seal up keychain access hole for unsigned applications.A security shortcoming in earlier versions of OS X has made its way into macOS High Sierra despite an expert’s best efforts to highlight the flaw. Patrick Wardle, of infosec biz Synack, found that unsigned, and therefore untrustworthy, applications running on High Sierra, aka macOS 10.13, were able to quietly access sensitive information – including stored passwords and keys – without any notification to the user. Normally, apps, even signed trusted ones, trigger a prompt to appear on screen when touching the operating system’s Keychain database of saved passphrases and other secrets.” ——- Title: Android unlock patterns are too easy to guess, stop using themURL: https://nakedsecurity.sophos.com/2017/09/28/android-unlock-patterns-are-too-easy-to-guess-stop-using-them/Date: 28 September 2017 Author: Lisa VaasExcerpt: “Let’s start with some things we knew already: people are really bad at creating and remembering secure passwords and PINs. We’re also bad at choosing and answering password recovery questions. Most of us can’t even cook up an unlock pattern for our Androids that’s not crazy easy to predict, be it by shoulder-surfing or the tell-tale streaks we leave with our greasy fingers. Now, a new report (PDF) from security researchers at the US Naval Academy and the University of Maryland Baltimore County has quantified just how absurdly easy it is to do an over-the-shoulder glance that accurately susses out an Android unlock pattern.” ——- Title: Deloitte Hit by Cyber-Attack Revealing Clients’ Secret EmailsURL: https://www.theguardian.com/business/2017/sep/25/deloitte-hit-by-cyber-attack-revealing-clients-secret-emailsDate: 25 September 2017 Author: Nick HopkinsExcerpt: “Deloitte, which is registered in London and has its global headquarters in New York, was the victim of a cybersecurity attack that went unnoticed for months. Deloitte provides auditing, tax consultancy and high-end cybersecurity advice to some of the world’s biggest banks, multinational companies, media enterprises, pharmaceutical firms and government agencies.
