104.28.156.67 has a threat confidence score of 67%. This IP address from Russia (AS13335, Cloudflare, Inc.) has been observed in 2 honeypot sessions targeting SSH protocols. Detected attack patterns include ssh shell history tampering via environment reload. First observed on April 8, 2026, most recently active April 8, 2026.
Identifies an SSH session where the actor manipulates shell environment variables (such as HISTFILE, HISTSIZE, HISTCONTROL, or related variables) and reloads or reinitializes shell history in order to suppress, overwrite, or control command logging. The combination of explicitly setting environment variables and triggering a history reload indicates deliberate command history tampering rather than normal shell usage.
