Attack Analysis

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.
Backup & Database File Probe
This IP requested common backup file paths (.bak, .sql, .zip, wp-config.bak), hunting for database dumps or config files containing plaintext credentials. A single exposed wp-config.bak can hand an attacker full database access. This attack is automated and deliberate.
Bad Bot Flood
This IP generated over 20 HTTP 4xx errors in 60 seconds using a User-Agent identified as a bad bot (scraper, headless browser, or attack proxy). The high error rate indicates automated probing for vulnerabilities while trying to appear as generic traffic. Legitimate services respect robots.txt and do not flood servers with errors.
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.
