How to remove BackLock Ransomware and decrypt .backlock files

What is BackLock Ransomware

BackLock Ransomware is a sophisticated malware strain identified by security researchers during investigations on VirusTotal, categorically falling into the file-encrypting ransomware family. Once it infiltrates a system, it proceeds to lock access to valuable data by encrypting files and appending a unique file extension—original filenames are altered with an identifier string followed by .backlock, for example, photo.jpg becomes photo.jpg.{victim's_ID}.backlock. The ransomware employs advanced encryption algorithms, typically based on asymmetric (public/private key) cryptography, which renders files inaccessible without a unique decryption key created during the attack and stored on remote cybercriminal servers. Users quickly notice the compromise, as they are unable to open their files, and every folder containing encrypted files includes a newly dropped README.TXT ransom note, instructing victims on how to establish contact with the attackers and pay for the promised decryption key. This message commonly warns users against using third-party recovery tools, threatening permanent data loss if external help is sought or encrypted files are altered.

Currently, no free or legitimate decryption tools are available for BackLock ransomware. Security experts advise victims not to pay the ransom, as there are no guarantees that paying will result in file recovery—cybercriminals may ignore payment requests altogether or provide faulty tools. If already affected, the only reliable course of action is to remove the ransomware using a reputable antivirus solution to prevent further encryption and system compromise. Decrypting .backlock files independently is not feasible without the attacker’s decryption key, since the underlying encryption mechanism is robust and professionally implemented. Victims are urged to check trusted resources like the No More Ransom Project for any emerging decryptors, but as of now, BackLock’s encryption is uncrackable. For future protection, daily system-wide data backups and rigorous cybersecurity hygiene are essential. It is also crucial to keep all software and operating systems up to date to close potential security loopholes that ransomware like BackLock exploits.

How BackLock Ransomware infects computers

BackLock Ransomware infiltrates computers primarily through deceptive tactics such as phishing emails and malicious attachments, where unsuspecting users are tricked into downloading and opening infected files. These files often come disguised as legitimate documents or software, exploiting common formats like ZIP archives, executables, and even seemingly harmless PDFs. Additionally, cybercriminals leverage drive-by downloads, where malware is automatically downloaded when users visit compromised or malicious websites, often without their knowledge. Unreliable download sources, such as peer-to-peer networks and third-party websites, are also notorious for bundling ransomware with seemingly innocent software. Another vector includes exploiting vulnerabilities in outdated software or operating systems, making it crucial for users to maintain regular updates and patches. By understanding these infection methods, users can take preventive measures to safeguard their systems against BackLock and similar ransomware threats.

How to protect computer from viruses, like BackLock Ransomware, in future

1. Get special anti-ransomware software

Use ZoneAlarm Anti-Ransomware

Famous antivirus brand ZoneAlarm by Check Point released a comprehensive tool, that will help you with active anti-ransomware protection, as an additional shield to your current protection. The tool provides Zero-Day protection against ransomware and allows you to recover files. ZoneAlarm Anti-Ransomware is compatible with all other antiviruses, firewalls, and security software except ZoneAlarm Extreme (already shipped with ZoneAlarm Anti-Ransomware) or Check Point Endpoint products. The killer features of this application are: automatic file recovery, overwrite protection that instantly and automatically recovers any encrypted files, file protection that detects and blocks even unknown encryptors.

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. BackLock 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.
