# SKILL: Unauthorized Access to Common Services — Expert Attack Playbook

> **AI LOAD INSTRUCTION**: Expert techniques for exploiting unauthenticated or weakly authenticated management services. Covers Redis write-to-RCE, Rsync data theft, PHP-FPM code execution, Ghostcat AJP file read, Hadoop YARN job submission, and H2 Console JNDI. These are infrastructure-level findings distinct from web application vulnerabilities.
