This rule detects potential execution of malicious files from removable media (e.g., USB drives). It monitors for a sequence of events where a removable drive is mounted, a file is subsequently created on that drive, and then that same file is executed within a short time window.
This rule detects potentially malicious activity associated with removable media (USB drives) by identifying two distinct patterns: first, the creation of an 'autorun.inf' file on a removable drive followed by the execution of a script or executable from that same drive shortly after. Second, it identifies executables appearing on removable media that are launched across multiple distinct hosts within a one-hour window, which may indicate worm-like spreading or mass-malware distribution via portable storage.

Detects file creation on a removable drive followed by process execution from that drive shortly after mounting.

Detects the NetworkShareScanner SMB/USB worm by known hash or by unsigned-executable propagation to remote shares/removable drives.
Detects the StopAndProtect VBS spreader (RegisterRC6inPlace.vbs / Payloadvbs.b64) propagating via removable media and/or WMI remote process creation.
Detects CountLoader's taskType 9 USB-worming behavior: a recently created/modified .lnk file on a non-system drive followed by mshta.exe execution referencing that .lnk with a remote HTTP(S) URL.
Detects the execution of wscript.exe, msiexec.exe, or cmd.exe initiated with command lines pointing to script files (.js, .vbs) or shortcut files (.lnk) located on removable drives (d-z drive letters). This behavior is characteristic of the Raspberry Robin worm spreading via infected USB media.
Detects LCRYX ransomware behavior involving the creation of autorun.inf files on removable drives combined with the execution of VBScripts from removable media using wscript.exe, indicative of a worm propagating via USB devices.
This rule detects two common persistence techniques: the modification of Windows Registry Run keys with paths referencing temporary or application data directories, and the creation of autorun.inf files on removable or non-system drives to facilitate potential code execution upon media insertion.
Detects the creation of executable files (.exe or .dll) on a removable drive followed by the execution of a process from that same drive within a 30-second window. This behavior is indicative of an adversary using removable media to stage and execute malicious payloads.
Detects the creation of executable files (.exe or .dll) on a removable drive followed by the execution of a process from that same drive within a 30-second window. This behavior is indicative of an adversary using removable media to stage and execute malicious payloads.
Detects the execution of wscript.exe, msiexec.exe, or cmd.exe initiated with command lines pointing to script files (.js, .vbs) or shortcut files (.lnk) located on removable drives (d-z drive letters). This behavior is characteristic of the Raspberry Robin worm spreading via infected USB media.
Detects anomalous file activity on removable media drives characteristic of the Gamaredon group's PteroOdd/PteroSetup malware. The rule identifies PowerShell, wscript.exe, or cscript.exe writing autorun.inf or .lnk files to removable drive letters (D-Z), which is a common technique for lateral movement and propagation via USB drives.
