Trick, Treat, Repeat: Patch Trends and Tooling for Q3

🎃 Microsoft’s free Windows 10 updates have largely ended, with EEA consumers receiving free Extended Security Updates through Oct 14, 2026, while most other users must pay. Q3 telemetry shows roughly 35,000 CVEs through September, averaging about 130 new entries per day, and a rising set of Known Exploited Vulnerabilities (KEV) that widen vendor and network impact. Talos also launched the Tool Talk series, offering a hands-on guide to dynamic binary instrumentation with DynamoRIO for malware analysis and runtime inspection.

North Korean Hackers Merge BeaverTail and OtterCookie

🔐 Cisco Talos reports that a North Korean-linked threat cluster has blended features of its BeaverTail and OtterCookie JavaScript malware families, with recent OtterCookie variants adding keylogging, screenshot capture, and clipboard monitoring. The intrusion chain observed involved a trojanized Node.js application called Chessfi and a malicious npm dependency published on August 20, 2025 that executed postinstall hooks to launch multi-stage payloads. Talos tied the activity to the Contagious Interview recruitment scam and highlighted continued modularization and abuse of legitimate open-source packages and public Git hosting to distribute malicious code.

Merged BeaverTail and OtterCookie Tooling Observed in Attacks

🔍 Talos uncovered a campaign linked to the DPRK-aligned cluster Famous Chollima that used a trojanized Node.js package and a malicious VS Code extension to deliver merged BeaverTail and OtterCookie tooling. The combined JavaScript payloads include a newly observed keylogger and screenshot module alongside clipboard theft, targeted file exfiltration, remote shell access, and cryptocurrency extension stealing. Indicators, C2 addresses, Snort/ClamAV detections, and mitigation guidance are provided.

OpenPLC and Planet WGR-500: Multiple Vulnerabilities

⚠️ Cisco Talos disclosed vulnerabilities affecting OpenPLC and the Planet WGR-500 industrial router, including a ModbusTCP denial-of-service and multiple critical flaws in HTTP-handling functions. The OpenPLC issue (TALOS-2025-2223 / CVE-2025-53476) can be triggered by a crafted series of TCP connections to exhaust the ModbusTCP server. Planet WGR-500 vulnerabilities (TALOS-2025-2226–2229 / CVE-2025-54399–54406, CVE-2025-48826) include stack-based buffer overflows, format string, and OS command injection flaws that may lead to memory corruption or arbitrary command execution.

ReVault: Deep Analysis of Dell ControlVault3 Firmware

🔒 This deep-dive by Philippe Laulheret (Talos) dissects Dell's ControlVault3 ecosystem, exposing firmware decryption, memory-corruption flaws, and exploit chains that cross the device/host boundary. The researchers recovered hardcoded keys, reverse-engineered the SCD/SMAU update mechanism, and achieved arbitrary code execution in firmware, enabling persistence and a demonstrated Windows Hello bypass. Practical attacks include forging SCD blobs, backdooring firmware to escalate to SYSTEM, and physically extracting the USH board over USB for rapid compromise.
