Attack Analysis

IDS: Blocklist — Spamhaus DROP
This IP is on the Spamhaus DROP list — a dataset of netblocks hijacked or leased by professional spam and cybercrime operations with no legitimate users. Traffic from DROP-listed ranges is considered hostile by design. Blocking is unconditional.
Port 22 Honeypot Probe
This IP connected to a fake SSH honeypot — a port 22 listener that is not a real SSH server. This is an automated scanner fingerprinting targets before launching a brute-force campaign. Legitimate systems never probe port 22 without a specific reason; this activity is virtually 100% malicious.
Suricata IDS Alert
Suricata intrusion detection flagged this IP for malicious network behaviour — including port scanning, exploit attempts, botnet activity, or known attack signatures. The specific signature is shown in the report list below.
PHP Stream Wrapper Exploitation Attempt
This IP's request contained a php://, data://, or expect:// stream wrapper — techniques used to read arbitrary server files, execute injected code, or bypass input filters via PHP's own I/O stream handling. An advanced exploitation technique, not accidental traffic.
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.
