How to remove Allock Ransomware and decrypt .allock8 files

What is Allock Ransomware

While inspecting new submissions to VirusTotal, researchers identified Allock Ransomware, a member of the MedusaLocker ransomware family. It renames files with a specific extension, notably .allock8, which can vary with the virus iteration. The ransomware employs sophisticated RSA+AES encryption, making file recovery difficult without the attackers’ involvement. Upon completion of the encryption process, it creates a ransom note named how_to_back_files.html and places it prominently on the desktop. This note informs victims of the data breach and demands payment for the decryption tools, along with the threat of leaking or selling stolen data if payment isn’t made.

To date, there are no publicly available decryption tools for Allock Ransomware. This lack of tools is due to the strong encryption algorithms employed by the malware, which are nearly impossible to crack without the unique keys held by the attackers. Victims are advised against paying the ransom, as there is no guarantee that attackers will provide the decryption keys. Instead, experts recommend isolating the infected machine to prevent further data loss and using data recovery tools to attempt retrieval of compromised files. The most reliable method for recovering from an .allock8 ransomware attack remains restoring data from up-to-date backups stored offline or on a cloud service, unaffected by the malware.

How Allock Ransomware infects computers

Allock Ransomware primarily infiltrates computers through phishing tactics and social engineering schemes. Cybercriminals often disguise malicious files as legitimate email attachments or bundle them with seemingly benign software downloads from untrustworthy sources. Once a user inadvertently opens these infected files, the malware executes and begins its encryption process, appending a unique .allock extension to the compromised files. Additionally, drive-by downloads from compromised websites and malicious advertisements can also serve as infection vectors. Users may unknowingly invite the ransomware into their systems by clicking on deceptive links or downloading software from peer-to-peer networks and unofficial sites. To mitigate such risks, it is crucial to maintain robust cybersecurity practices, including regularly updating software, avoiding suspicious emails, and employing reliable antivirus solutions.

2. Back up your files

As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. Allock 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. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox

Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
