Description

Detects the first time a Python process accesses sensitive credential files on a given host. This behavior may indicate post-exploitation credential theft via a malicious Python script, compromised dependency, or malicious model file deserialization. Legitimate Python processes do not typically access credential files such as SSH keys, AWS credentials, browser cookies, Kerberos tickets, or keychain databases, so a first occurrence is a strong indicator of compromise.

Detection logic

Its licence does not clear it for publishing here

Sunturai publishes a detection's own text where the licence it arrived under has been reviewed and permits it, and Elastic License 2.0 has not. The query as its source wrote it, its canonical form and the hash that pins this revision are in the workspace record.
