What happened
SANS ISC reports on CVE-2024-40766 noting that while a patch addresses the underlying software bug, affected deployments remain insecure because configurations were not corrected. The diary emphasizes that patching code alone is insufficient without configuration hardening and offers broader context across other recent incidents (webshells, phishing using IPv4-mapped IPv6 addresses, coordinated SSH brute force activity, and a VHDX-to-Remcos malware case). Operators should verify applied patches, audit and remediate insecure configuration settings, and review related telemetry for signs of post
