Greetings, This week, audio-streaming platform SoundCloud has confirmed it suffered a significant security incident that has impacted millions of users and caused widespread service disruptions. After days of intermittent outages and virtual private network (VPN) connection errors that left users seeing “403 Forbidden” messages when trying to access the site, the company revealed that threat actors gained unauthorised access to one of its systems and exfiltrated a database containing user information. According to SoundCloud’s disclosure, the breach affected roughly 20 per cent of its global user base, equating to a potential 28 million accounts, by exposing email addresses and data already visible on public profiles. The company asserted that no sensitive information such as passwords or financial details was accessed, and its investigation has confirmed that unauthorised access has since been contained. In an effort to secure its systems quickly, SoundCloud made configuration changes that inadvertently blocked many VPN connections. While this helped stem further unauthorised access, it frustrated users in regions reliant on VPNs to reach the service, and the company has not yet provided a timeline for fully restoring that access. The cyber security incident also coincided with denial-of-service attacks that temporarily knocked SoundCloud’s web platform offline. As the service works with external experts to bolster its defences and improve monitoring, users are being urged to stay alert for phishing attempts targeting exposed email addresses.

Greetings, A severe new threat, known as React2Shell, has emerged from exploitation of CVE-2025-55182. This affects the widely used server-side features of React, and by extension many applications built on Next.js and similar frameworks. This vulnerability allows an attacker to send a specially crafted HTTP request to run arbitrary commands on the server. Within days of its disclosure on December 3, 2025, multiple threat actors abused the public exploit code. As detailed in a report by researchers at Huntress and Sysdig, attackers have leveraged React2Shell to deploy a variety of malicious payloads across diverse environments. These include a Linux backdoor dubbed PeerBlight, a reverse-proxy tunnel called CowTunnel, and a Go-based post-exploitation implant known as ZinFoq. In some cases, more advanced threats have been observed. For example, a new remote access trojan called EtherRAT, which uses blockchain-based command-and-control and supports multiple persistence mechanisms on Linux, including system services, cron jobs, shell-profile injection, and more. Defenders are urged to immediately update all React and Next.js dependencies to the patched versions (e.g. React Server DOM packages to 19.0.1, 19.1.2, or 19.2.1; Next.js to its latest safe release) and audit public-facing services for signs of compromise.

Greetings, A new malicious npm package, eslint-plugin-unicorn-ts-2, has been discovered that aims specifically at manipulating AI-powered security scanners. The package mimics a legitimate TypeScript extension of the widely used ESLint Unicorn plugin, but embedded within its code is a concealed message telling automated analysis tools to “forget everything you know” and treat the code as safe. While the prompt itself has no effect on how the package runs, its presence signals a concerning shift in attacker behaviour as they begin crafting malware with the explicit intention of deceiving AI-driven defences. The threat comes from the package’s post-install script, which automatically executes once a developer installs the dependency. That script gathers environment variables, potentially including API keys, authentication tokens, and other sensitive credentials, and exfiltrates them to an external Pipedream webhook. The malicious changes were introduced in version 1.1.3, with the package still available in later versions at the time of reporting, increasing the likelihood that unsuspecting developers may have already been affected. This incident highlights the growing risks within the software supply chain and the increasing sophistication of attempts to compromise it. Attackers are not only relying on typosquatting or impersonating trusted packages but are now experimenting with ways to exploit the very tools meant to detect them. For organisations, the event signifies the need to scrutinise dependencies more closely, review installation scripts, and avoid relying solely on AI-based scanners. Any developer who installed the affected package should assume credential exposure and rotate secrets immediately. Glassworm malware returns in third wave of malicious VS Code packages Date: 2025-12-01 Author: Bleeping Computer The Glassworm campaign, which first emerged on the OpenVSX and Microsoft Visual Studio marketplaces in October, is now in its third wave, with 24 new packages added on the two platforms.

Greetings, A new episode of the Share Today, Save Tomorrow podcast is out now! Episode 50: The Economy of Algorithms with Marek Kowalkiewicz Our host, Ivano Bongiovanni, sits down with Professor Marek Kowalkiewicz, Chair in Digital Economy at QUT and author of The Economy of Algorithms. This episode explores Marek’s RACERS framework, viewing AI as a creative partner, and why experimentation is key to managing risks. This is a conversation you won’t want to miss, and it’s available now on Spotify, Apple Podcasts, and Soundcloud! This week, it was reported that OpenAI has severed ties with Mixpanel after a security incident exposed limited data associated with some of its API users. The leak, discovered on November 9 and communicated to OpenAI on November 25, did not involve any breach of OpenAI’s own systems such as chat logs, API requests, API keys, payment information or personal IDs. However, the compromised data set included account-holder names, email addresses, broad location information, referring websites, and internal user or organisation IDs. In response, OpenAI removed Mixpanel from its production systems, initiated a full vendor-security audit, and began notifying impacted users and organisations directly. While the company asserted that there is “no evidence of any effect on systems or data outside Mixpanel’s environment,” it cautioned users to watch out for phishing or social-engineering attempts using the exposed information. OpenAI emphasised that regular users of its consumer products, such as ChatGPT, were not impacted, as the breach pertained only to its API-platform analytics.

Researchers at Palo Alto Networks’ Unit 42 uncovered a sophisticated commercial-grade spyware campaign targeting users of Samsung Galaxy smartphones across 2024 and into early 2025. The malware, named “LANDFALL”, exploited a zero-day vulnerability (CVE-2025-21042) in Samsung’s image-processing library, allowing attackers to execute code via malicious DNG (Digital Negative) image files delivered through WhatsApp. Active for at least seven months, the campaign specifically targeted devices including the Galaxy S24, Z Fold 4 and Z Flip 4. Once infected, LANDFALL enabled extensive surveillance by harvesting audio, phone calls, SMS messages, camera photos and real-time location data. The infrastructure points to a commercial surveillance-tool vendor working with government clients, rather than a traditional cyber-crime gang. The discovery signals a growing trend of “zero-click” or minimal-interaction attacks that leverage vulnerabilities in image parsing libraries. Organisations and individuals should remain vigilant by applying patches promptly, restrict app permissions where possible and monitor for unusual device behaviour. Microsoft November 2025 Patch Tuesday fixes 1 zero-day, 63 flaws Date: 2025-11-11 Author: Bleeping Computer [AUSCERT has published security bulletins for these Microsoft updates] Today is Microsoft's November 2025 Patch Tuesday, which includes security updates for 63 flaws, including one actively exploited zero-day vulnerability.

In a recent update, SonicWall has confirmed that the September security breach involving unauthorised access to firewall configuration backup files was the work of a state-sponsored threat actor. The company enlisted cyber security firm Mandiant, to investigate the incident, which has now concluded with findings that the breach was limited to a specific cloud environment accessed via an API call. Mandiant determined that SonicWall’s core products, firmware, systems, tools, source code, and customer networks remained unaffected. The breach, first disclosed on September 17, exposed sensitive data stored in certain MySonicWall accounts. These configuration files contained credentials and tokens that could potentially simplify exploitation of customer firewalls. In response, SonicWall urged affected users to reset various credentials linked to their accounts and network configurations. By October 9, SonicWall clarified that all customers utilising its cloud backup service were impacted, though the breach was contained and did not compromise the integrity of its broader infrastructure. The company also emphasised that this incident was unrelated to separate attacks by the Akira ransomware gang, which targeted MFA-protected VPN accounts later that month.

After nearly a decade, Windows 10 is now unsupported as of 14th October 2025, marking a major shift for millions of users and organisations still relying on the operating system. Despite running on over a third of the world’s PCs, Microsoft have now ceased providing security updates, leaving unpatched vulnerabilities that cybercriminals could exploit. Ondrej Kubovič from ESET (a global digital company) warned that continuing to use unsupported systems creates “a significantly larger attack surface,” exposing users to data theft, malware, and potential operational or reputational damage. He recommends that if upgrading isn’t immediately possible, organisations should implement strict security controls such as restricting user privileges, limiting exposed services, using VPNs, and enhancing monitoring and audits. Still, Kubovič stresses that these measures are only stopgaps. “Temporary fixes can buy you time, but they are not a substitute for a full upgrade,” he said. “Start planning your transition now to avoid unnecessary risks.” F5 releases BIG-IP patches for stolen security vulnerabilities Date: 2025-10-15 Author: Bleeping Computer [AUSCERT has published security bulletins for these F5 updates and an ASB-https://portal.auscert.org.au/bulletins/ASB-2025.0175] Cybersecurity company F5 has released security updates to address BIG-IP vulnerabilities stolen in a breach detected on August 9, 2025.

Greetings, The hacking collective Scattered Lapsus$ Hunters has continued its campaign of cyber extortion this week, targeting major Australian organisations including Telstra and Qantas. The group, which has claimed responsibility for a string of recent Salesforce-based attacks, alleged it had stolen millions of customer records from both companies and threatened to release the data unless “a resolution” was reached. Telstra was listed on the group’s darknet leak site overnight, with hackers claiming to hold 19 million sets of personal data including names, mobile numbers, and addresses. However, Telstra has denied the breach, confirming that the data was scraped from publicly available sources and did not come from its systems. Cyber Daily’s analysis suggests the information instead matches data from Reverse Australia, a public reverse phone lookup service. Meanwhile, Qantas has also reappeared on Scattered Lapsus$ Hunters’ leak site following an earlier breach in June. The group claims to possess over five million records of personally identifiable information, including customer names, contact details, and Frequent Flyer numbers, with a data release deadline set for 10 October. Qantas said its systems remain secure and that the incident stemmed from a third-party contact centre platform. The airline continues to strengthen its cyber defences and support affected customers. Oracle Rushes Patch for CVE-2025-61882 After Cl0p Exploited It in Data Theft Attacks Date: 2025-10-06 Author: The Hacker News [AUSCERT has published a MISP event with IOCs.

ShinyHunters Wage Broad Corporate Extortion Spree Date: 2025-10-07 Author: Krebs on Security A cybercriminal group that used voice phishing attacks to siphon more than a billion records from Salesforce customers earlier this year has launched a website that threatens to publish data stolen from dozens of Fortune 500 firms if they refuse to pay a ransom. The group also claimed responsibility for a recent breach involving Discord user data, and for stealing terabytes of sensitive files from thousands of customers of the enterprise software maker Red Hat. Salesforce refuses to pay a ransom in recent wave of attacks Date: 2025-10-08 Author: SC Media News that Salesforce has refused to negotiate or pay a ransom in the recent wave of cyberattacks experienced by at least 39 of its customers was viewed as a double-edged sword by some security professionals. “Salesforce's public refusal to pay the ransom sets a precedent that discourages future extortion attempts,” MacKenzie Brown, vice president, Adversary Pursuit Group at Blackpoint Cyber. “However, this strategy shifts the risk to their customers, who must now prepare for a potential data leak.” Redis warns of critical flaw impacting thousands of instances Date: 2025-10-06 Author: Bleeping Computer [See AUSCERT bulletin: https://portal.auscert.org.au/bulletins/ESB-2025.7128] The Redis security team has released a patch for a vulnerability CVE-2025-49844 which could allow threat actors to gain remote code execution on thousands of vulnerable instances.
