When a PHP server is compromised, a systematic response is critical. This workflow starts with webshell detection, using file integrity checks and scanning for suspicious PHP files. Next, it traces the root cause of RCE vulnerabilities, often through log analysis and patch review. Finally, it ensures complete removal of backdoors and trojans, including persistence mechanisms. The approach emphasizes documentation and verification at each step. For DevOps and security teams, having a repeatable incident response plan reduces downtime and prevents recurrence. This guide is a practical reference for both emergency response and proactive hardening.
