What it detects

This rule detects execution of the .dev-env/config.sh helper script through bash, the staging and exfiltration routine dropped by the Shai-Hulud worm. The script bundles harvested secrets and pushes them to attacker infrastructure, so its execution indicates active collection and exfiltration on a compromised developer or build host.
