Attack Analysis

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.

FireHOL level2 — FireHOL level2 lists addresses seen attacking in the last 48 hours across many sensors. It is large and volatile: addresses enter and leave quickly, so on its own this is weaker, recent-activity evidence.

Only short-lived or context lists match, so this is weak evidence on its own.
