Threats Tagged 'usb'

Tangerine Turkey is a cryptomining campaign that propagates via VBScript worms spread through USB drives, leveraging legitimate system binaries for execution and persistence. The malware employs advanced defense evasion techniques such as registry modification and masquerading malicious files as legitimate system components. It establishes persistence through malicious services and scheduled tasks while attempting to disable Windows Defender. Although its primary objective is unauthorized cryptocurrency mining, its capabilities for persistence and lateral movement pose broader security risks. The campaign uses living-off-the-land binaries and creates mock directories to conceal its activities. No known CVEs or exploits are currently associated with this threat. The medium severity rating reflects the financial motivation and potential for system compromise without immediate destructive impact. European organizations using Windows systems with USB access are at risk, especially those with lax endpoint security controls and high-value targets. Mitigation requires targeted controls beyond generic advice, including USB device management, monitoring for living-off-the-land abuse, and registry integrity checks.
