Detects HTTP traffic from internal hosts to the 'gapidriver.com' domain, specifically identifying the GapiUpdate stager behavior. The rule looks for authenticated GET requests to '/api/get.php' using a specific Bearer token and User-Agent, as well as status reporting to '/api/rest.php'.
This rule detects processes accessing sensitive credential, configuration, or environment files typically stored in locations like .aws, .ssh, .kube, or application user directories. It alerts when a non-standard or unexpected process touches multiple sensitive folders, or when specific suspicious process names or known malicious tools (such as 'NeedleStealer') are observed interacting with these files. This is indicative of potential credential harvesting or reconnaissance activities.

Detects established raw-TCP C2 communication sessions associated with the GapiUpdate Go-based RAT, identifying both known malicious infrastructure and behavioral anomalies characteristic of long-lived, encrypted C2 persistence.

This rule detects potential command-and-control beaconing activity associated with the Go RAT used in the GapiUpdate campaign. It monitors for outbound network connections over TCP port 5556 to a known malicious C2 IP address, or alternatively, detects persistent outbound activity to other external (non-RFC1918) IP addresses characterized by multiple successive connections within a 10-minute window, which mimics the behavior of persistent beaconing.
