139.59.173.250 has a very high threat confidence level of 98%, originating from Slough, United Kingdom, on the DigitalOcean, LLC network (14061). It has been observed across 107 sessions targeting SSH, HTTP, with detected attack patterns including ssh hardened host profiling and shell rc immutability bypass, First observed on February 17, 2026, most recently active March 10, 2026.
Identifies SSH post-auth activity combining resilient multi-source CPU enumeration (explicit /usr/bin/nproc fallback) with removal of the immutable flag from ~/.shellrc via chattr, indicating host profiling followed by shell configuration tampering for persistence preparation.
Identifies HTTP requests targeting the web server root path ("/"), typically used for initial service discovery, host validation, or baseline content inspection prior to deeper enumeration.
