What it detects

This rule detects curl uploading an archive named out.zip on macOS. The SHAMOS stealer delivered by COOKIE SPIDER collects credentials and wallet files and exfiltrates them in an out.zip archive via curl. A curl invocation referencing this archive name is a high-fidelity exfiltration indicator.
