If we defraud even one client, other clients will not pay us. In 5 years, not a single client has been left dissatisfied after making a deal with us.

Technical Analysis of LockBit 5.0

The LockBit 5.0 Windows version was found to have a better user interface with clean formatting for affiliates compared to previous versions.

It describes various options and settings for executing the ransomware, including basic options like specifying directories to encrypt or bypass, operation modes such as invisible mode and verbose mode, notes settings, encryption settings, filtering options and examples of usage.

"The detailed commands and parameters illustrate the flexibility and customization available to the attacker," the researchers commented.

Upon execution, the ransomware generates its signature ransom note and directs victims to a dedicated leak site. The infrastructure maintains LockBit's established victim interaction model, featuring a streamlined "Chat with Support" section for ransom negotiations.

Notably, the variant adds randomized 16-character file extensions to files following encryption, further complicating recovery. LockBit 5.0 also omits traditional markers at file endings, making analysis harder.

The malware deploys other anti-forensic techniques. This includes patching the EtwEventWrite API by overwriting it with a 0xC3 (return) instruction, disabling Windows Event Tracing capabilities.

As with previous LockBit versions, the new iteration uses geolocation checks, terminating execution when detecting Russian language settings or Russian geolocation.

The features observed in the Windows version were similar to those in the Linux and ESXi variants analyzed.

The ESXi variant specifically targets VMware virtualization infrastructure, which the researchers said represents a "critical escalation" in LockBit's capabilities.

This is because ESXi servers typically host multiple virtual machines, allowing attackers to encrypt entire virtualized environments with a single payload execution.
