Amazon: Threat Actor Exploited Cisco and Citrix Zero-Days

⚠️ Amazon's threat intelligence team disclosed that it observed an advanced threat actor exploiting two zero-day vulnerabilities in Citrix NetScaler ADC (CVE-2025-5777) and Cisco Identity Services Engine (CVE-2025-20337) to deploy a custom web shell. The backdoor, disguised as an IdentityAuditAction component, operates entirely in memory, uses Java reflection to inject into running threads, and registers a Tomcat listener to monitor HTTP traffic. Amazon observed the activity via its MadPot honeypot, called the actor highly resourced, and noted both flaws were later patched by the vendors.

Microsoft fixes Windows Task Manager bug hurting performance

⚠️ Microsoft released a fix for a Windows 11 Task Manager issue introduced by the optional preview update KB5067036 that could leave multiple taskmgr.exe processes running after the window was closed. The defect, blamed for stuttering and CPU hangs on affected systems, is resolved in the November cumulative security update KB5068861. Microsoft recommends installing KB5068861, and users who cannot immediately update can temporarily terminate lingering Task Manager processes by running an elevated Command Prompt and executing taskkill.exe /im taskmgr.exe /f.

Microsoft Patches 63 Flaws Including Kernel Zero‑Day

🔒 Microsoft released patches for 63 vulnerabilities, four rated Critical and 59 Important, including a Windows Kernel zero-day (CVE-2025-62215) that Microsoft says is being exploited in the wild. The flaws span privilege escalation, remote code execution, information disclosure and DoS, with notable heap-overflow issues in Graphics Component and WSL GUI. Administrators are urged to prioritize updates where exploits are known or where vulnerabilities permit privilege escalation or remote code execution.

Microsoft Fixes Windows Kernel Zero Day in November

🔒 Microsoft released its November Patch Tuesday updates addressing over 60 CVEs, including an actively exploited Windows kernel zero-day (CVE-2025-62215). The flaw is a race-condition and double-free that can let low-privileged local attackers corrupt kernel memory and escalate to system privileges, though exploitation requires precise timing and local code execution. Administrators should also prioritise a critical GDI+ RCE (CVE-2025-60724, CVSS 9.8) that can be triggered by parsing specially crafted metafiles. Microsoft additionally issued an out-of-band update (KB5071959) to resolve Windows 10 Consumer ESU enrollment failures.

Pixnapping vulnerability: Android screen-snooping risk

🔒 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 patches critical hardcoded credentials in SQL Anywhere

🔒 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.

Attackers Exploit Critical Triofox Flaw for Code Execution

⚠️ 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.

CISA Adds Samsung Zero-Day Used to Deploy LandFall Spyware

🛡️ 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.

Triofox Authentication Bypass Leads to Remote Access

🔒 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.
