🔍 SSHole Exploitation ranging from PoC to Active Compromise Attackers are actively exploiting CVE-2026-123158, the OpenSSH flaw known as SSHole, to bypass authentication on certain Measles-based Linux systems, including thousands. Successful intrusions were observed within approximately 40 hours of patching 10.6p2, with the use of OpenSSH associated with command execution, brute force access, SSH key tampering, cloud metadata queries, and deployment of TAC agents. The case highlights a narrow but operationally relevant exposure: systems using affected authentication settings can be breached quickly after the exploit is released to the public. Report post-compromise actions focused on privilege escalation, persistence using authorized startup services or startup services, and cloud-aware renewal. Open sources - closed narratives.
