LockBit Ransomware Strikes Again: Now Targeting Apple macOS Devices

Introduction of LockBit Ransomware

LockBit ransomware, known for targeting Windows systems, has now set its sights on macOS devices.
This article explores the recent development of LockBit targeting Apple’s macOS operating system and its implications for cybersecurity.

MalwareHunterTeam reports the emergence of LockBit’s macOS-based payload, a significant shift from its previous focus on Windows.
vx-underground identifies macOS variant samples dating back to November 11, 2022, previously undetected by anti-malware engines.

LockBit, a cybercrime group linked to Russia, has been operational since late 2019, rolling out significant updates in both 2021 and 2022.
Recent statistics from Malwarebytes reveal LockBit as the second most used ransomware, indicating its widespread impact.

Security researcher Patrick Wardle notes that while the macOS variant is still in development, it relies on an invalid signature, limiting its execution on Apple devices.
The payload contains artifacts suggesting its origin as a Windows-targeting ransomware, indicating ongoing development efforts.

Apple’s built-in security features such as System Integrity Protection (SIP) and Transparency, Consent, and Control (TCC) offer protection against unauthorized code execution and data access.
While the macOS LockBit variant lacks data exfiltration capabilities and persistence methods, it highlights the evolving threat landscape.

Despite limitations, LockBit’s development for macOS signals a growing trend of threat actors targeting macOS systems.
While macOS may offer some resilience against ransomware attacks, organizations should remain vigilant and implement additional security measures.

LockBit’s expansion to macOS underscores the need for heightened cybersecurity measures across all platforms.
Collaboration between security researchers, organizations, and law enforcement is crucial to mitigate the threat posed by ransomware groups like LockBit.
