What it detects

This rule detects reading a dotenv secrets file and posting its contents to a remote host using wget post-data, an exfiltration pattern observed after React2Shell RCE. Attackers grab application secrets from the .env file to pivot into connected cloud and database services. The combination of the .env path and an outbound HTTP post argument reflects deliberate credential theft rather than routine tooling.
