Water Selkie’s operators have indicated a preference for victims in Europe who fear breaching EU’s General Data Protection Regulation (GDPR).

It considers external pressures and issues faced by its potential targets.

The threat group’s efforts to publicize their malware’s capabilities have established it as the ransomware with one of the fastest and most efficient encryption methods. The malware’s speed and capabilities are widely known because the group uses them as selling points.

The malware’s performance is a strong selling point.

Our investigation into the intrusion set behind LockBit, which we track as Water Selkie, reveals the effectiveness and impact of the tactics we have discussed. Additionally, this test build has some similarities with its Linux counterpart.

However, upon analysis, it appears that they are likely a test build and lack the functionality to run on Mac devices. It is believed that these encryptors have been active since December 2022. In April 2023, researchers from MalwareHunterTeam discovered LockBit ransomware encryptors targeting Mac devices.

LockBit’s timeline of notable activities Recent LockBit developments Moreover, the gang is seeking vulnerabilities in the Tor network to better ascertain their operation’s security and ensure that their root access servers are not compromised.įigure 1. They are looking for vulnerabilities related to TOX messenger, suggesting that the group relies heavily on the platform for communication.

Water Selkie is also offering compensation for ideas that can improve their software development and operation. The hefty reward incentivizes hackers to discover a vulnerability that the gang considers as a warning that their operation is at risk. The affiliate manager, referred to as LockBitSupp, has offered $1 million to anyone who can provide the identity of the members of the ransomware group. The group’s reward for the contribution of security researchers ranges from US$1,000 to $1 million. The gang urges security researchers to submit vulnerability reports to improve their operations in exchange for remuneration. (we link to the blog in development once published.) The malware observed from the samples were detected by Trend Micro as for LockBit 3.0 and for the unpacked sample provided by Twitter user release of LockBit 3.0 is significant because it also launched the group’s bug bounty program, the first initiative of its kind for ransomware operations.

While this is common for some ransomware, the code used in this case is very similar. Both BlackMatter and LockBit 3.0 also used the same method of identifying logical drives. It also has the same implementation of NtSetInformationThread to hide a thread from a debugger. The two variants show that they use the same codes to resolve its needed API functions. Our debugging process found that LockBit 3.0’s code is very similar to that of DarkSide and BlackMatter, which other researchers also noted. It also contains a command-line argument feature.

Twitter user found a sample of the LockBit 3.0 ransomware version and noted that the malware uses anti-analysis techniques to hide itself and does not execute without a password like BlackCat. In late June 2022, the LockBit ransomware gang reportedly launched LockBit 3.0, the latest known variant of the group’s ransomware, after two months of beta testing with the new malware deployed in the attacks. LockBit 3.0: Sharpening the saw with a bug bounty program LockBit also reportedly published a small part of the stolen data from the attack. Experts suspect that an insider helped the group gain access to the firm’s network.

The tactics we’ve enumerated are evident in their attack on Accenture in 2021.

Using such tactics, the LockBit group has built itself into one of the most professional organized criminal gangs in the criminal underground.

It has been known to hire network access brokers, cooperate with other criminal groups (such as the now defunct Maze), recruit company insiders, and sponsor underground technical writing contests to recruit talented hackers. This variant is capable of targeting Linux hosts and could have a big impact on targeted organizations.Īnother side of LockBit’s operations is its recruitment of and marketing to affiliates. In October 2021, LockBit also expanded to Linux hosts, specifically ESXi servers, in its release of Linux-ESXI Locker version 1.0. This tool was seen with the release of LockBit 2.0, which has been touted by its creators for having the fastest and most efficient encryption among its competition. One of its notable tactics was the creation and use of the malware StealBit, which automates data exfiltration. Its double extortion methods also adds more pressure to victims, raising the stakes of their campaigns. LockBit uses a ransomware-as-a-service (RaaS) model and consistently conceived new ways to stay ahead of its competitors.
