Microsoft's October Patch Tuesday marks this Windows Shell security feature bypass (CVSS 8.8) as 'Exploitation Detected'. CISA added it to KEV on Oct 13 (listed as a Windows command injection) with an Oct 16 federal due date. Patch Windows endpoints first.

Authentication bypass by spoofing leading to remote command execution (CVSS 8.6). Listed in CISA KEV on Oct 13 with an Oct 16 due date. Apply Ivanti's fix and review appliance integrity.

Not known exploited, but high-value: Exchange Server RCE CVE-2026-70571 (8.1) and AD Domain Services RCE CVE-2026-70229 (8.1), both 'Exploitation More Likely'; Outlook RCEs at 9.8 such as CVE-2026-70242; Message Queuing RCE CVE-2026-100202 (9.8); DHCP Server RCE CVE-2026-96934 and QUIC RCEs. Severity and exploitability labels are Microsoft's.

Both campaigns end in web-server-spawned shells and miners. Look for the web service process spawning cmd/powershell/sh, new script files in web roots, and outbound connections to mining pools.

Tune the parent list to your stack. Sketch only; validate before alerting.

Review SMA1000 access logs for unauthenticated requests to unusual Work Place paths, and investigate unexpected connections from the appliance to internal services. Rotate credentials for anything reachable through the appliance's trust context.

Built around Claude Code: recon, known-CVE scanning and attack-surface ranking. Caveats: third-party community project, not audited by us; needs Claude Code or API access and won't run fully on local models without changes; only point it at targets you're authorized to test.

Open-source taskflows for the seclab-taskflow-agent framework that use an LLM to plan, build and triage fuzzing harnesses. Caveats: needs model API access and real compute; LLM-written harnesses still need human review, and crashes are not vulnerabilities until triaged.
