What is BuLock Ransomware

BuLock ransomware is a virus that encrypts files on victims’ computers and asks them to pay ransom money in return for the decryption key. This dubious threat is data locker malware, created by hackers to blackmail innocent users and make an illegal profit. It is capable of infecting any Windows PC very easily. It mostly intrudes on the targeted machine in disguise and users don’t even suspect the presence of this malware until their files are locked. This nasty BuLock Ransomware uses a powerful encryption algorithm to lock files on an infected computer which can only be unlocked by a private decryption key.

BuLock File Virus

After encrypting files on the targeted machine, it appends the “.BuLock” file virus extension to the original file names. This is a way of marking files as inaccessible and the extension usually refers to the name of the virus. All the files encrypted by this virus can allegedly be opened by a decryption key which hackers are offering for a price. A ransom note is also left on the infected PC with instructions for how to pay ransom money, how much, and when to pay. Hackers usually demand ransom money through Bitcoin which cannot be tracked.

Working of bulock16 File Virus

Ransomware threats are created with the sole motive of making an illegal profit online. They cipher all the files stored on the infected PC whether it is a video, audio, picture, database, backup, or any other personal file type. Such viruses are capable of encrypting almost all types of files that normally users store on their computers. So if your system gets infected by Ransomware then all your files will still be there but you lose their access.

Every time you try to open your files, you will get an error. The only reason is that the extension of your files is changed. Now your system cannot decide the type of file and thus it cannot open the file for you. This BuLock File Virus uses a military-grade encryption algorithm that makes your files unreadable. According to the ransom note left on the compromised PC, buying a decryption key is the only way to restore those files in their original format.

How BuLock Ransomware Infects Your PC

Cybercriminals use different methods to spread their creation online to target a mass audience. Spam email campaigns are one the most used methods to spread threats like BuLock File Virus on a massive level. Hackers create and send fake emails to a bunch of people using bulk emailing software.
