This guide provides a structured methodology for hypothesis-driven threat hunting focused on detecting web shell deployment (T1505.003) on internet-facing servers. It analyzes file creation in web directories, suspicious child-process generation from web server processes, and anomalous HTTP request patterns. Use this during incident response, proactive security assessments, or when EDR/SIEM alerts indicate web server process anomalies.

Scans web server roots for high-entropy files, suspicious PHP/JSP/ASP payloads, and recent modifications to flag obfuscated webshells via entropy thresholds, regex signatures, and file metadata.
