Attack Analysis

Reconnaissance Behind Browser Disguise
This IP generated repeated HTTP 4xx errors (404/403) while spoofing a legitimate browser User-Agent (Chrome, Firefox). Real browsers do not repeatedly trigger 4xx errors in rapid succession — this is an automated scanner disguised as human traffic to evade bot detection.
