As the most well-known name in ransomware attacks, LockBit has now been linked to other attacks in the past. In this article, we look at all you need to know about LockBit’s operation.
What is Ransomware?
Ransomware is a piece of malware or malicious software that is frequently introduced into the computer network of an organization through a phishing attempt. This entails deceiving the recipient into downloading the malicious file, usually by clicking on an email’s link or attachment. By tricking the target into believing they are logging on to the network in question, phishing attempts can also attempt to obtain the target’s username and password.
After that, the malware encrypts affected PCs, preventing content access. In order to unlock or decrypt those machines, the rogue actor behind the assault then demands money from the impacted entity, which is usually a business or government agency.
What is LockBit Ransomware?
LockBit ransomware is a ransomware group that has recently gained media attention. LockBit, once referred to as ABCD ransomware, has evolved into a distinct danger within the context of these extortion tools.
Furthermore, LockBit ransomware targets businesses via email attachments and trickling file system infestations. In contrast to previous ransomware strains that target individuals and businesses, LockBit primarily targets government agencies and businesses.
LockBit has been used in major worldwide attacks, most notably in September 2019. At that time, it was called the “.abcd virus.” The name was a reference to the file extension used by LockBit when encrypting a victim’s files.
LockBit operates as a ransomware-as-a-service platform where interested parties can pay a deposit to utilize customized assaults and earn revenue through an affiliate network.
How does LockBit Ransomware work?
LockBit ransomware follows these phases in its operation;
#1. Exploitation:
The original LockBit ransomware intrusion resembles previous malicious attacks. It might make use of social engineering techniques like phishing, in which hackers pose as reputable individuals or authorities in order to get login credentials. Brute-force attacks on the network systems and intranet servers of a company are also possibilities.
LockBit prepares the system to release its encrypting payload on every device it can after infiltrating a network. However, an attacker might have to carry out a few additional tasks before making their final move.
#2. Infiltration:
LockBit will distribute the ransomware’s encryption component after taking all required security measures. This includes disabling any additional infrastructure that enables system recovery as well as security software. The goal of infiltration is to render recovery without assistance impossible or so slow that the only way out is to pay the ransom that the attacker requests. The victim will pay the ransom when they are in a desperate attempt to get back to their normal activities.
#3. Deployment:
Once the network is sufficiently ready for LockBit, the ransomware will start infecting every machine it comes into contact with. Every system file will be “locked” while the encryption is being done. The only way to unlock the computers of the victims is by using a unique key produced by LockBit’s in-house decryption tool. Every system folder also contains copies of a simple text file that contains a ransom letter. In certain LockBit versions, it has even included threats of blackmail and instructions for the victim to restore their system.
Types of LockBit Ransomware
Some of the most noteworthy variations to be aware of are listed below:
#1. Variant 1: . abcd extension:
The encrypted files in the original LockBit version had the suffix “.abcd” added to them. Then, it puts a ransom note called “Restore-My-Files.txt” with payment and data recovery instructions within each folder.
#2. Variant 2: . LockBit extension:
The most recent version of LockBit stores encrypted data with the “.LockBit” file extension. With a few changes to the backend code, it has many of the same traits as its predecessor.
#3. Variant 3: LockBit version 2:
The necessity to download the Tor browser is lessened by the latest version of the LockBit ransomware. Rather, it sends victims to a webpage where they can see how to retrieve files and make fees.
#4. Variant 4: LockBit version 3.0:
LockBit 3.0, also referred to as “LockBit Black,” functions according to the Ransomware-as-a-Service (RaaS) concept. Attcakers use it to attack important infrastructure and enterprises using a variety of strategies. It is quite adjustable and can be changed while it is being used to fit the goals of the attacker. Only computers without language settings that match a specified exclusion list—which is ascertained by a configuration flag provided during compilation—will be infected. Initial access is obtained via a number of techniques, including the abuse of legitimate accounts, phishing campaigns, RDP exploitation, and public-facing application exploitation.
Furthermore, LockBit 3.0 encrypts files, modifies the host’s background and icons, and has the ability to transmit encrypted data to a command and control server. It also leaves a ransom note.
In addition, it might erase itself from the hard drive and reverse any Group Policy changes that were done. Before encrypting important company data, LockBit 3.0 affiliates use openly accessible file-sharing sites and bespoke exfiltration tools like Stealbit.
How to protect against LockBit ransomware
The following exercises can assist you in becoming ready:
#1. Use secure passwords whenever possible.
Easy-to-guess passwords—those that are straightforward enough for an algorithmic program to figure out within a few days of probing—are the cause of many account breaches. Make sure you select secure passwords by using longer ones with different characters and creating passphrases according to the standards you’ve defined for yourself.
#2. Turn on two-factor verification.
By adding layers to your initial password-based logins, you can prevent brute-force attacks. When feasible, implement security safeguards on every system you use, such as physical USB key authenticators or biometrics.
#3. Review the permissions for user accounts.
Strict permission requirements prevent such dangers from getting through unabated. Particular attention should be paid to those endpoint users and IT accounts with administrator-level access. Enterprise databases, online meeting services, collaborative platforms, and web domains should all be protected.
#4. Delete unused and out-of-date user accounts.
There may be accounts from former employees in certain older systems that were never closed or canceled. Eliminating these possible weak spots should be part of a thorough system check-up.
#5. Verify that all security protocols are being followed by system configurations.
Reexamining current configurations may take some time, but doing so could disclose fresh problems and out-of-date guidelines that expose your company to danger. Regular reviews of standard operating procedures are necessary to keep them up to date and protect against emerging cyber threats.
#6. Always keep clean local machines and backups of the entire system on hand.
Accidents may occur, and having an offline copy is your only real defense against irreversible data loss. Your company has to periodically create backups in order to stay current on any significant system modifications. Consider keeping several rotating backup locations with the ability to choose a clean period in case a backup becomes polluted with a virus infection.
#7. Make sure you’ve implemented a thorough corporate cybersecurity solution.
Enterprise cyber security protection software will assist you in catching file downloads throughout the full corporation with real-time protection, even if LockBit can attempt to eliminate protections once in a unit.
