What is Onelock Ransomware
Onelock is a ransomware infection developed by the Medusa ransomware family. Its purpose is to encrypt access to potentially important data (using RSA and AES encryption algorithms) and extort money from victims for full decryption. While rendering files inaccessible, the virus adds the new .onelock extension, which would make a file like
1.pdf change to
1.pdf.onelock and reset its original icon. The same pattern applies to other files that get targeted by the infection. After successful completion, Onelock creates the how_to_back_files.html file to feature decryption instructions.

Overall, it is said that ransomware developers are the only figures able to decrypt victims’ data. For this, victims are therefore instructed to contact cybercriminals using a chat link in Tor Browser (or e-mail) and pay some specified amount of ransom. In case victims decide to resign from paying for the decryption, extortionists promise they will publish the collected data, which may become a threat to the privacy of individuals or the reputation of businesses. Before paying the ransom, cybercriminals also offer to test if their decryption actually works – victims are allowed to send 2-3 non-important files and get them decrypted for free. The note also warns against using third-party tools for data decryption as this may lead to permanent damage. Unfortunately, much of what cybercriminals claim in terms of decryption is true – usually, initial ransomware developers are the only figures able to provide full and flawless decryption of data. Although paying a ransom is usually the only way to decrypt your data and prevent the publication of data, there is still a risk that cybercriminals may fool you and not send any decryption tools or even publish your data regardless of payment. Therefore, the necessity of paying the ransom should be evaluated by each person experiencing ransomware infections. Regardless of whether a working third-party decryptor exists or not, victims can also recover their data using backup copies (if such are available). Even so, the publication of data will still remain a threat if victims refuse to collaborate with cybercriminals. Below, you will find some recommendations of reputable third-party decryptors, however, please note that none of them has been successful in decrypting .onelock files at this moment. You can give them a try if no other alternative is left to consider. Please note that prior to trying any recovery/decryption that does not include the participation of cybercriminals, it is important to delete the infection from your computer so that it does not continue its malicious activity. Read our guide below to learn how to do this and also establish protection against such threats in the future.
How Onelock Ransomware infected your computer
Ransomware and other infections are commonly spread via e-mail spam letters, trojans, deceptive third-party downloads, fake software updates/installers, backdoors, keyloggers, botnets, system exploits, and some other distribution channels as well. Such channels employ social engineering/phishing techniques designed to fool inexperienced users into opening some malicious content (usually attachments or links). For instance, ransomware or trojans can be disguised as some legitimate file (.DOCX, .XLSX, .PDF, .EXE, .ZIP, .RAR, or .JS extensions) and distributed through e-mail letters that imitate names of legal companies/entities (e.g., delivery companies, tax authorities, banks, and so forth). In order to trick inexperienced users into executing the attached content, cybercriminals may name files in clickbait ways and claim it is “important” or “urgent” to read them. If the attached content ends up opened according to cybercriminals’ guidelines, the contained infection will be deployed for installation on the targeted system. To prevent drive-by (stealth) installations of malware, it is important to avoid downloading software from unofficial resources (Peer-to-Peer websites, torrent pages, landing pages, etc.) and beware of opening content that looks suspicious. We also encourage you to read our guide below and learn how one can protect his PC against threats like ransomware (or other malware) in the future.

How to protect computer from viruses, like Onelock 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. Onelock 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.
