New TONTOU CPU attack bypasses Spectre v2 fixes, leaks Linux password hashes
August 6, 2026
Back to all postsA new cyber threat named TONTOU has emerged, targeting Linux systems. This attack exploits a vulnerability in modern CPUs that was previously thought to be fixed following the Spectre v2 incident. TONTOU can bypass these fixes and leak password hashes of running processes, posing a significant security risk for Canadian businesses utilizing Linux servers or workstations. The attacker can gain unauthorized access to sensitive data and system configurations, potentially leading to data breaches or system takeovers. To protect their systems, SMB owners and IT managers in Canada should prioritize updating and patching their Linux systems regularly, implementing multi-factor authentication, and employing robust security measures such as intrusion detection and prevention systems.
