Detects a sequence of actions often used to bypass macOS Gatekeeper protections: removing the quarantine extended attribute using 'xattr -c' on a file in the /tmp directory, followed by making that file executable with 'chmod +x', and finally executing the file. This behavior is indicative of malicious software attempting to evade Apple's security checks for downloaded files.

This rule detects the presence of ZigCryptoStealer malware deployed via a NativeAOT-compiled Windows executable. The detection relies on identifying specific hardcoded infrastructure strings, such as a BNB Smart Chain RPC endpoint and a specific contract address used to resolve C2 domains. It also looks for common sideloading hosts associated with the malware's delivery.

Sweeps DeviceFileEvents, DeviceProcessEvents, and DeviceNetworkEvents over a rolling 30-day window for known RevStealer indicators: exact SHA-256 matches against all 13 published file hashes, and exact-host matches (via parsed URL host, not substring) against the confirmed C2 domain meta7.archscreen68.one. An empty, extensible IP list is included for when a malicious IP is published.

This rule monitors for indicators of compromise (IOCs) associated with the threat actor SideCopy and their associated malware, such as ReverseRAT. It hunts for specific malicious SHA256 file/process hashes, connections to known malicious C2 infrastructure (IPs and domains), requests to known malicious URLs, and user interaction with these URLs via email clicks.
