Detects the execution of staged payloads from the Windows %TEMP% directory. This rule monitors for suspicious activity often associated with loader-style C2 execution, including direct execution of randomly named files, proxy execution via rundll32 or regsvr32, silent MSI installations, and the execution of payloads extracted from archives in temporary locations.

Detects execution of rnpkeys.exe from the C:\ProgramData\keyroll\ directory, which is indicative of Sauron Loader side-loading activity, followed by an outbound network connection on port 443 within a 5-minute window. This behavior is consistent with the initial bot registration beaconing phase of the malware.

Detects potential JWT algorithm-confusion or authentication-bypass attempts
targeting WSO2 API Manager components through JWTs specifying unsupported,
downgraded, or unexpected signing algorithms such as "none" or HS256 where
asymmetric signing is expected. Matching events should be investigated to
determine whether the request represents exploitation of CVE-2026-5430.
