Lockbit ransomware is a creation of hackers that works in the underground network and therefore, identifying the culprit for the spread of this hazardous virus is quite not possible. Including the computer, servers, and internet connection they are using are passing through hidden channels that do not disclose their location. Lockbit ransomware spread campaign utilizes this concealed platforms in order to distribute copies of the virus to random victims without a trace.
How Lockbit Virus Reaches the Computer?
The fact is, Lockbit ransomware has no specific target in the majority of attacks and the virus is spread throughout the internet and those who can catch it becomes the prey. For example, attackers incorporates Lockbit ransomware to spam email messages and sends it to a collection of email addresses, which they have gathered from previous malware infection, or may have bought from the underground network of hackers. Lockbit ransomware usually arrives in the inbox as normal letter from prominent organization and the subject as well as the sender does not appear suspicious at all. Furthermore, it holds an influential message that can easily persuade the recipients to open the attached file. That is the period when Lockbit ransomware will start the initial infection.
Next to phishing scam, hackers also find success to distribute the virus using maliciously modified freeware as well as infected pirated copies of commercial software. Because these files are already executable, it is much easier for the virus to initialize during the setup process. Computer users are totally unaware of the infection proceedings because Lockbit ransomware cleverly conceals its malicious activities on the system.
Links from website comments, forums, and social media sites are also helpful in the propagation of Lockbit ransomware. These malicious links will open a browser page or redirect the current window to an infected website that will download the payload carrier.
.Lockbit File Encryption/Decryption
After infecting the computer, Lockbit ransomware do not proceed with the file encryption at once. It may still gather basic computer and network information that it will send to a remote server. Then, it waits for a command and public key. Once obtained Lockbit ransomware performs file-locking actions and applies the public key along with the high-level encryption method. In addition, the virus inserts .lockbit file extension to encrypted data. That being said, the normal billing.doc converts to billing.doc.lockbit.
Subsequently, a ransom note file is generated on the computer informing victims on the file encryption occurrence. It also gives a warning that any unnecessary modifications on the encrypted file will permanently cause damage. Here is an excerpt from the ransom note Restore-My-Files.txt.
All your important files are encrypted!
Any attempts to restore your files with the third-party software will be fatal to your files!
Restoring your data is possible only when buying private key from us…
As of this moment, there is no free way to decrypt all .lockbit files. Hence, we will update this page once the dedicated decryption software is on hand.

How to protect the computer from Lockbit ransomware?
After the removal of the ransomware, it is important to prevent similar incident from happening again. In order to protect the computer effectively, computer user must know how Lockbit ransomware was able to infect the computer. To minimize the possible infection, staying away from the common sources of this virus is crucial.
How Lockbit ransomware can infect your computer?
The method of infecting the computers was found to be similar as other common viruses. Though, ransomware like Lockbit is seen to have efficient deployment via spam email messages, web injectors, malicious software installers, misleading online advertisements, and through another virus infection.
Once the virus is executed, it immediately infects the system. Then, Lockbit ransomware communicates to remote server so that unique key can be generated for the specific computer. After acquiring the key, it starts to decrypt target files using a complex method that is almost unbreakable. On the last stage of the attack, Lockbit ransomware demands for ransom money as payment for the decryption tool. To further understand the attack scheme, we have included an infographic below.
Securing the computer against ransomware attack
Do a Regular File Back-up - Always backup your data on a separate storage devices such as external hard drives, optical discs, or online backup services.
Keep Your Software Updated - Make sure that you have the latest software updates especially on the operating system. Recent updates often contain vital security patches to help protect the computer against all forms of threats.
Install a Security Program - Protect the computer with effective anti-virus application using efficient real-time scanning. Regularly run a complete scan to check the computer for presence of malware.
Protect your files with Controlled Folder Access (Windows 10)
For Windows 10 users, aside from protecting the computer using anti-virus or anti-malware programs, one way to protect against ransomware attack is by using Controlled Folder Access. This feature of Windows Defender Security Center may not prevent the Lockbit ransomware infection, but it can protect the folder and files in general. Follow the steps to enable Controlled Folder Access in Windows 10.
