Convert indexed Sigma rules into analyst-ready detections.
This studio is built around Phoenix's own rule corpus, not a blank editor. Search by title or rule id, choose a local pySigma backend, then reveal pipelines only when you actually need them.

description: |
Detects post-exploitation access to the wp2shell webshell plugin dropped after successful
exploitation of CVE-2026-63030 and CVE-2026-60137. After the pre-auth SQLi-to-admin bridge is established,
the attacker can upload a malicious plugin (wp2shell) to the target WordPress instance.
At this phase, the attacker accesses the webshell for command execution and persistence.
