📡 Detection & Monitoring

Log Indicators:

  • Unusual POST requests containing serialized PHP objects
  • Unexpected file creation/modification in WordPress directories
  • Suspicious process execution from web server user

Network Indicators:

  • HTTP requests with serialized data payloads to WordPress admin-ajax.php or similar endpoints
  • Outbound connections from web server to unknown external IPs

SIEM Query:

source="web_logs" AND (uri="*admin-ajax.php*" OR uri="*wp-admin*" OR uri="*dzs*" ) AND (data="*O:*" OR data="*C:*" OR data="*a:*" )
