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.

Detects DNS queries to attacker-controlled infrastructure used by the Mini Shai-Hulud campaign targeting TanStack npm packages along with other packages such as mistralai, uipath and so on.
The domain git-tanstack.com (registered May 9, 2026) hosted secondary payloads including transformers.pyz.
The filev2.getsession.org endpoint was used for credential exfiltration via the Session protocol.
