The detection is based on identifying processes running outside of the standard C:\\ drive which are known to be used by the Mustang Panda APT.  The original detection logic was published on 2026-04-13. Defenders should be aware that this detection might require adjustments based on their specific system configurations and drive mappings. It highlights the importance of monitoring for suspicious process execution from removable media, a common initial access vector used by threat actors like Mustang Panda.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker gains initial access by delivering malware via a USB drive or other external storage device.
