What is BuLock Ransomware

BuLock Ransomware is a type of malicious software, or malware, that encrypts files on a victim’s computer or network, rendering them inaccessible. The attackers then demand a ransom from the victim in exchange for the decryption key to unlock the files. The ransomware is also known as a Crypto Virus or Files Locker due to its encryption capabilities. BuLock Ransomware adds the .bulock16 extension to the files it encrypts. The digit in the extension may vary depending on the ransomware variant. BuLock Ransomware uses a combination of RSA and AES cryptographic algorithms to encrypt files. These are robust encryption methods that make it challenging to decrypt the files without the specific decryption key. BuLock Ransomware creates a ransom note named HOW_TO_BACK_FILES.html. This note informs the victim that their network has been compromised and their files encrypted. It also warns that the attackers have exfiltrated confidential data from the network, which they threaten to sell or leak online if the ransom is not paid. The note also offers the victim the chance to test decryption on 2-3 files before paying the ransom.

Decrypting .bulock16 files is challenging due to the robust encryption used by BuLock Ransomware. Without a specific decryption key, it’s nearly impossible to decrypt the files. The best course of action is to restore the files from a backup if one is available. It’s also recommended to keep backups in multiple different locations, such as remote servers and unplugged storage devices, to ensure data safety.

How BuLock Ransomware infects computers

Ransomware like BuLock can infect computers through various methods. The most common include phishing emails using social engineering, malvertising, fileless attacks, remote desk protocol, drive-by downloads, pirated software, and network propagation. For instance, an attacker might spoof a CEO’s email and trick employees into clicking a link in a fake email, thereby infecting the company’s network. As of the current date, there are no free decryption tools available for BuLock Ransomware. However, it’s always worth checking resources like the No More Ransom Project or Avast’s free ransomware decryption tools for updates.

BuLock Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface.
