🔒 Microsoft released its November 2025 Patch Tuesday addressing 63 vulnerabilities across Windows, Office, Visual Studio and other components, including five labeled Critical. One important kernel elevation flaw, CVE-2025-62215, has been observed exploited in the wild. Critical issues include RCE in GDI+, Office, and Visual Studio, plus a DirectX elevation-of-privilege; Microsoft rates several as less likely to be exploited. Cisco Talos published Snort and Snort 3 rules and advises customers to apply updates and rule packs promptly.

🔒 A newly disclosed exploit named Pixnapping (CVE-2025-48561) allows a malicious Android app with no special permissions to read screen pixels from other apps and reconstruct sensitive content. The attack chains intent-based off-screen rendering, translucent overlays, and a GPU compression timing side channel to infer pixel values. Google issued a September patch but researchers bypassed it, and a more robust fix is planned.

🔒 SAP released November security updates addressing a maximum-severity (10.0) hardcoded credentials flaw in the non-GUI component of SQL Anywhere Monitor (CVE-2025-42890) and a critical code-injection issue in SAP Solution Manager (CVE-2025-42887). The embedded credentials could allow attackers to access administrative functions and potentially execute arbitrary code. Administrators should apply updates and follow SAP mitigation guidance promptly.

⚠️ Mandiant and Google GTIG observed UNC6485 exploiting a critical improper access control flaw, CVE-2025-12480, in Gladinet Triofox versions prior to 16.7.10368.56560. Attackers spoofed a localhost Host header to reach setup pages, create a native 'Cluster Admin' account and upload payloads. They abused the product's anti‑virus configuration to execute arbitrary scripts as SYSTEM, then deployed remote access tools, escalated privileges and exfiltrated credentials. Users are urged to update, audit admin accounts and hunt for indicators of compromise.

🛡️ US federal agencies have been directed to patch a critical Samsung zero-day exploited to deploy spyware on mobile devices. The out-of-bounds write flaw CVE-2025-21042 (CVSS 9.8) was patched by Samsung in April, but Palo Alto Networks reports it has been used in a campaign since mid-2024. Commercial spyware LandFall was embedded in malicious DNG images and distributed via WhatsApp, with possible zero-click remote code execution. CISA added the bug to its KEV catalog and requires mitigation or discontinuation by December 1.

🔒 Google's Mandiant reported active n‑day exploitation of a critical authentication bypass in Gladinet's Triofox (CVE-2025-12480, CVSS 9.1) that lets attackers access configuration pages and execute arbitrary payloads. Adversaries abused the product's antivirus executable path to run a malicious batch, installing Zoho UEMS and remote‑access tools such as Zoho Assist and AnyDesk. Operators created admin accounts, escalated privileges, and established SSH tunnels for inbound RDP. Triofox customers should apply the vendor patch, remove unauthorized admins, and verify antivirus executable paths cannot run untrusted scripts.

🔒 CISA has ordered U.S. federal agencies to patch a critical Samsung vulnerability, CVE-2025-21042, which has been exploited to deploy LandFall spyware via malicious DNG images sent over WhatsApp. The flaw is an out-of-bounds write in libimagecodec.quram.so affecting devices on Android 13 and later; Samsung issued a patch in April after reports from Meta and WhatsApp security teams. CISA added the bug to its Known Exploited Vulnerabilities catalog and requires Federal Civilian Executive Branch agencies to remediate by December 1 under BOD 22-01. The spyware can exfiltrate data, record audio, and track location.

⚠️ A critical remote code execution vulnerability (CVE-2025-12735) has been disclosed in the popular expr-eval JavaScript expression parser, which sees over 800,000 weekly downloads on NPM. Reported by Jangwoo Choe and rated 9.8 by CISA, the flaw stems from insufficient validation of the variables/context object passed to Parser.evaluate(), allowing attacker-supplied function objects to be invoked during evaluation. Both the original project and its maintained fork are affected; the fork provides a fix in v3.0.0. Developers should migrate to the patched fork and republish dependent packages immediately.

🔒 Security researcher Secure Annex discovered a malicious extension in the Microsoft Marketplace that embeds "Ransomvibe" ransomware for Visual Studio Code. Once the extension activates, a zipUploadAndEcnrypt routine runs, applying typical ransomware techniques and using hard-coded C2 URLs, encryption keys and bundled decryption tools. The package appears to be a test build, limiting immediate impact, but researchers warn it can be updated or triggered remotely. Microsoft has removed the extension and says it will blacklist and uninstall malicious extensions.

⚠️ Mandiant Threat Defense observed active exploitation of an unauthenticated access control vulnerability in Gladinet's Triofox (CVE-2025-12480) that allowed attackers to bypass authentication and reach administrative setup pages. By manipulating the HTTP Host header to impersonate localhost, attackers accessed protected admin workflows, created a native admin account, and configured the built-in anti‑virus engine to execute a malicious script as SYSTEM. The chain led to a PowerShell downloader, installation of a legitimate Zoho UEMS agent, and deployment of remote access tools; the vulnerability affected Triofox 16.4.10317.56372 and was mitigated in 16.7.10368.56560. Operators should upgrade immediately, audit admin accounts, and restrict anti‑virus engine paths.

🔒 A new low-cost hardware-assisted attack called TEE.fail undermines current trusted execution environments from major chipmakers. The method inserts a tiny device between a memory module and the motherboard and requires a compromised OS kernel to extract secrets, defeating protections in Confidential Compute, SEV-SNP, and TDX/SDX. The attack completes in roughly three minutes and works against DDR5 memory, meaning the physical-access threats TEEs are designed to defend against are no longer reliably mitigated.

🔔 CISA has added one vulnerability to its Known Exploited Vulnerabilities (KEV) Catalog: CVE-2025-21042, an out-of-bounds write in Samsung mobile devices that CISA reports is being actively exploited. This class of flaw can enable code execution or device compromise and poses a significant risk to the federal enterprise. Under BOD 22-01, Federal Civilian Executive Branch agencies must remediate listed KEVs by required due dates. CISA strongly urges all organizations to prioritize timely remediation and to apply vendor updates and mitigations without delay.

⚠ Three high-severity vulnerabilities in the runc container runtime allow attackers to escape containers and gain host-level privileges by abusing masked paths, console bind-mounts, and redirected writes to procfs. Aleksa Sarai of SUSE and the OCI described logic flaws that let runc mount or write to sensitive /proc targets, including /proc/sys/kernel/core_pattern and /proc/sysrq-trigger. Patches are available in runc 1.2.8, 1.3.3 and 1.4.0-rc.3; administrators should update promptly, favor rootless containers where feasible, and monitor for suspicious symlink behaviour.

⚠️ Three newly disclosed vulnerabilities in runC (CVE-2025-31133, CVE-2025-52565, CVE-2025-52881) could allow attackers to bypass container isolation and obtain root write access on the host. The issues involve manipulated bind mounts and redirected writes to /proc, and one flaw affects runC releases back to 1.0.0-rc3. Patches are available in recent runC releases; administrators should update, monitor for suspicious symlink/mount activity, and consider enabling user namespaces or running rootless containers as mitigations.

🔒 A threat actor exploited a Samsung Android image-processing zero-day, CVE-2025-21042, to deliver a previously unknown spyware called LandFall using malicious DNG images sent over WhatsApp. Researchers link activity back to at least July 23, 2024, and say the campaign targeted select Galaxy models in the Middle East. Unit 42 found a loader and a SELinux policy manipulator in the DNG files that enabled privilege escalation, persistence, and data exfiltration. Users are advised to apply patches promptly, disable automatic media downloads, and enable platform protection features.

🔒 A now-patched out-of-bounds write in libimagecodec.quram.so (CVE-2025-21042, CVSS 8.8) was used as a zero-click vector to deliver commercial-grade Android spyware known as LANDFALL. The campaign appears to have used malicious DNG images sent via WhatsApp to extract and load a shared library that installs the spyware. Unit 42 links activity to targets in Iraq, Iran, Turkey, and Morocco and notes samples dating back to July 2024. The exploit also deployed a secondary module to modify SELinux policy for persistence and elevated privileges.

⚠️ Cisco warned that two recently patched firewall vulnerabilities (CVE-2025-20362 and CVE-2025-20333) — previously leveraged in zero-day intrusions — are now being abused to force ASA and FTD devices into unexpected reboot loops, causing denial-of-service. The vendor issued updates on September 25 and strongly urged customers to apply fixes immediately. CISA issued an emergency 24-hour directive for U.S. federal agencies and ordered EoS ASA devices to be disconnected. Shadowserver still reports tens of thousands of internet-exposed, unpatched devices.

🔍 Unit 42 disclosed LANDFALL, a previously unknown commercial-grade Android spyware family that abused a Samsung DNG parsing zero-day (CVE-2025-21042) to run native payloads embedded in malformed DNG files. The campaign targeted Samsung Galaxy models and enabled microphone and call recording, location tracking, and exfiltration of photos, contacts and databases via native loaders and SELinux manipulation. Apply vendor firmware updates and contact Unit 42 for incident response.
