Attack Analysis

Webshell Filename Probe
This IP requested a filename commonly used by webshells and backdoors (c99.php, wp_filemanager.php, and similar) — hoping a previous compromise, on this site or elsewhere, already dropped one at this exact path. A hit would hand the attacker a ready-made remote-control panel with no exploitation needed.

Webshell Upload Scan
This IP rapidly probed multiple non-existent PHP paths in under 60 seconds — a hallmark of automated webshell scanning tools hunting for previously uploaded backdoors or vulnerable file-upload endpoints. If successful, a webshell grants the attacker full remote code execution on the server.
