The persistent menace of Lockbit ransomware continues to wreak havoc on organizations worldwide. A Security advisory, issued by esteemed cybersecurity agencies, sheds light on the alarming rise of Lockbit as the most prevalent ransomware variant in 2022 and its continued prevalence in 2023, with recent activity reported as recently as late May. The National Cyber Security Centre (NCSC), in collaboration with agencies from the United States, Australia, Canada, France, Germany, and New Zealand, has released this advisory to equip organizations with the necessary tools and knowledge to mitigate the likelihood and impact of future Lockbit incidents.

Lockbit’s Impact and Target Sectors: Since January 2020, Lockbit affiliates have launched attacks on organizations of all sizes across critical infrastructure sectors, including finance, agriculture, education, and healthcare. The NCSC confirms Lockbit as the most deployed ransomware strain in the UK during 2022, posing a significant threat to organizations within the country. This joint advisory aims to provide valuable insights into Lockbit’s operational techniques, the tools employed by its affiliates, and recommended mitigation strategies for network defenders.

Understanding Lockbit’s Operation: The advisory reveals that Lockbit operates under a ‘Ransomware-as-a-Service’ model, wherein cybercriminals sell access to their ransomware variant to unaffiliated affiliates while offering support for executing attacks. It also highlights the pervasive risk of double extortion, a tactic often employed by ransomware actors, where they encrypt victim systems and exfiltrate sensitive information, threatening to release it unless a ransom is paid.

Guidance and Mitigation Measures: The NCSC emphasizes the severity of ransomware attacks and their potential consequences on operational efficiency, financial stability, and reputation. With this advisory, the NCSC, along with its international partners, underscores the urgency for network defenders to implement recommended actions to establish robust protections against Lockbit and similar ransomware threats. Moreover, the NCSC’s ransomware hub provides comprehensive guidance and advice to assist organizations in understanding, mitigating, and responding to ransomware attacks. It’s important to note that the NCSC, in alignment with law enforcement, does not endorse, promote, or encourage ransom payments.

Conclusion: Lockbit ransomware poses a persistent and significant threat to organizations globally, and the joint advisory serves as a critical call to action for network defenders. By understanding Lockbit’s operational mechanisms, employing recommended mitigation strategies, and staying informed through the NCSC’s resources, organizations can fortify their defenses and safeguard against the detrimental impacts of ransomware attacks. The collaboration between international agencies underscores the shared responsibility in combating cyber threats and protecting the global digital landscape.
