LockBit is a cybercriminal group proposing ransomware as a service (RaaS), which means they provide their ransomware to other threat actors through an affiliate model. This allows different cybercriminals to use their ransomware toolkit in exchange for a percentage of the ransom payments.
The group emerged around 2019 and has since gained notoriety for its sophisticated and impactful ransomware attacks.
Here are some key points about the LockBit cybercriminal group:
- Ransomware Development:
LockBit is associated with the development and deployment of the LockBit ransomware. This ransomware strain is designed to encrypt files on a victim’s system and, like many other ransomware variants, is known for demanding payment in exchange for the decryption key. - Double Extortion:
LockBit, like some other advanced ransomware groups, employs a tactic known as “double extortion”. In addition to encrypting files, the attackers exfiltrate sensitive data from the victim’s network. They threaten to release this data publicly unless the victim pays the ransom. - Targeted Attacks:
LockBit has been known to target organizations, including businesses and enterprises. These attacks are often financially motivated, seeking a significant ransom payment.
The group conducts thorough reconnaissance to identify and exploit vulnerabilities within high-value targets. - Delivery Methods:
Ransomware like LockBit is typically delivered through phishing emails, malicious attachments, or exploiting vulnerabilities in software and systems. Once inside a network, the ransomware moves laterally, encrypting files on multiple systems. - Advanced Techniques:
LockBit utilizes advanced evasion techniques to avoid detection and escalate privileges within compromised networks. Living-off-the-land tactics involve using legitimate tools within the target environment for malicious activities, contributing to the group’s ability to navigate and exploit systems effectively. - Affiliate Model:
LockBit operates on an affiliate model, collaborating with other cybercriminals who play a role in the distribution and deployment of the ransomware. Affiliates are typically responsible for gaining initial access to target networks, and they receive a share of the ransom payments. - Ransom Payments:
The group typically demands payment in cryptocurrency, such as Bitcoin, to make it more challenging to trace transactions. However, paying the ransom does not guarantee that the attackers will provide the decryption key, and there are ethical and legal concerns associated with making ransom payments. - Evolution and Updates:
The LockBit cybercriminal group continually evolves its tactics, techniques, and procedures (TTPs) to adapt to cybersecurity defenses and law enforcement measures. Updates to the ransomware strain may include new evasion techniques, encryption algorithms, or methods for lateral movement within a network. - Global Impact:
LockBit’s activities have had a global impact, causing data breaches, operational disruptions, and significant financial losses for victimized organizations.
