It states:

All your files are encrypted by LockBit
for more information see Restore-My-Files.txt that is located in every
encrypted folder

No other changes are observed at this time, but more aggressive malvertising campaigns are expected this month, pushing this variant of the LockBit ransomware.

LockBit Ransomware – How Did I Get It and What Does It Do?

The newly reported .abcd LockBit ransomware is a dangerous malware which is being run by an unknown hacking group. There is no information available about the identity of the criminals at this moment. At a later date more information will probably be uncovered. What we know so far is that the attacks are not targeting a certain region.

Viruses like this one can be spread to the intended users using a variety of the common distribution techniques. Usually they will focus on carrying out phishing campaigns that will manipulate the victims into believing that the shown contents is legitimate and safe. The hackers will impersonate the contents, domain names and layout of well-known companies and services and present the virus code to the users. A common strategy is to send out email messages that are sent in a bulk-like manner that may also remind the users of SPAM notifications. The hacking group can also create and maintain such scam sites.

The malware infection can also be caused by the interaction with virus-infected files. They can be either documents of all popular formats which when opened will display a prompt asking the victims to enable the built-in scripts. The reason quoted is that this is required in order to display the contents. If this is done the virus will be delivered. The other popular mechanism is to create malicious app installers — they are made by taking the original setup packages and modifying them to include the relevant virus code. All files can then be easily spread over different file-sharing networks.

What we know is that the origins of this .abcd LockBit virus are from a Russian-speaking country. Not a lot of samples have been captured which gives us reasons to believe that the sent malware samples are probably early versions or test releases. The behavior can change depending on the local machine conditions or the exact hacker instructions.

A common action which is undertaken by similar threats is the initial data harvesting which will hijack personal information that can expose the identity of the users. The gained intelligence can be used for other crimes like identity abuse and financial abuse. Along with a report on the installed hardware components an unique infection ID can be generated.

The next step in the process will probably be a security bypass function. It starts after the data harvesting has completed as it may use the information. This module will search for any installed programs and services that may block the proper running of the ransomware. Commonly this module will act against firewalls, intrusion detection systems, anti-virus programs and others.

File-encrypting viruses like this one may also lead to widespread system changes. Common actions will include the following malware activities:

  • Boot Options Changes — The virus can edit out the configuration settings so that the ransomware will start every time the computer is powered on. Advanced samples can also disable access to the recovery boot options thereby making it very difficult to remove the active infections.
  • Data Removal — Many viruses like the .abcd LockBit malware contain instructions that will deliberately delete sensitive user data. This can include not only user data, but also backups and Shadow Volume Copies.
  • Windows Registry Changes — Changes to the Windows Registry can lead to the creation of new strings related to the virus or the modification of already installed ones. Consequences of these actions can be severe performance problems, data loss and unexpected errors.
  • Virus Infections With Other Malware — Having already compromised the security of the computers the .abcd LockBit virus can also be used to deploy other threats such as Trojans and cryptocurrency miners.

The encryption engine will work as expected by processing user files with a strong cipher and making them inaccessible. Example data which will be affected includes the most popular user files:

  • Archives
  • Backups
  • Documents
  • Multimedia Files

All encrypted files will receive the .abcd extension and will be extorted to pay a ransomware decryption fee. The instructions to do so are found in a text files that will be automatically created by the engine called Restore-My-Files.txt.
