The W2tnk virus was originally discovered by virus analyst Tomas Meskauskas, and belongs to the Hive ransomware family. This ransomware encrypts all user’s data on the PC (photos, documents, excel tables, music, videos, etc), adds its specific extension to every file.
W2tnk Virus
☝️ W2tnk can be correctly identify as a Hive ransomware-type infection.
After the encryption process files will be renamed according to the pattern w2tnk, which is laid in ransomware. Your photo, named an example “me.jpg” will be altered to “me.jpg.KtUB5y9YUIkhr-nE5uQFND-LsaLA025U9cGyRLCb1y-qJC4Fb46kGCqxHHef6dlu.w2tnk” after the encryption.
Inside of the ransom note, there is usually an instruction saying about purchasing the decryption tool. This decryption tool is created by ransomware developers.
Here is a summary for the W2tnk:

How did I get W2tnk ransomware on my computer?
That was a huge number of different ways of ransomware injection.
However, nowadays there are only two ways of W2tnk injection – email spam and trojans. You may see a lot of messages on your email, stating that you need to pay different bills or to get your parcel from the local FedEx department. But all such messages are sent from unknown email addresses, not from familiar official emails of these companies. All such letters contain the attached file, which is used as a ransomware carrier. If you open this file – your system will get infected by W2tnk.
In case of trojans presence, you will be offered to download and install ransomware on your PC under the guise of something legit, like a Chrome update, or update for the software you are storing on your computer. Sometimes, trojan viruses can be masked as legit programs, and ransomware will be offered for download as an important update, or a big pack of extensions which are essential for proper program functioning.
There is also the third way of ransomware injection, however, it becomes less and less popular day-to-day. I am talking about peering networks, such as torrents or eMule. No one can control which files are packed in the seeding, so you can discover a huge pack of different malware after downloading. If circumstances force you to download something from peering networks – scan every downloaded folder or archive with antivirus software.
How to remove W2tnk virus?
In addition to encode a victim’s files, the W2tnk virus has also started to install the Azorult Spyware on computer to steal account credentials, cryptocurrency wallets, desktop files, and more.
To ensure the user that ransomware distributors really have the decryption tool, they may offer to decrypt several encrypted files. And they are the single owners of this decryption program: W2tnk ransomware is a completely new type, so there is no legit program from anti-malware vendors, which can decrypt your files. But such a situation is in momentum: decryption tools are updating every month.
However, paying the ransom is a bad decision, too. There is no guarantee that W2tnk ransomware developers will send you the decryption tool and a proper decryption key. And there are a lot of cases when ransomware distributors deceived their victims, sending the wrong key or even nothing. In the majority of cases, there is a way to recover your files for free. Search for available backups, and restore your system using it. Of course, there is a chance that the backup you found is too old, and does not contain a lot of files you need. But, at least you will be sure that there is no malware in your system. However, to ensure that there are no malicious programs in your system after the backup, you need to scan your PC with anti-malware software.
W2tnk ransomware is not unique. There are more ransomware of this type: Tohnichi, Cvuch, Axiom. These examples of ransomware act in a similar way: encrypting your files, adding a specific extension, and leaving a great number of ransom money notes in every folder. But there are two things which make difference between these ransomware – cryptography algorithm, which is used for file encryption, and ransom amount . In some cases, victims are able to decrypt their files without any payments, just using free solutions produced by several anti-malware vendors, or even with the decryption tool which is offered by ransomware creators. The last scenario is possible when ransomware distributors have typed your decryption key inside of a ransom money note. However, as you can already guess, such luck is a very rare thing. Ransomware is created for money gaining, not for jokes or scaring.

Frequently Asked Questions
No way. These files are encrypted by W2tnk ransomware. The contents of .w2tnk files are not available until they are decrypted.
If your data remained in the .w2tnk files are very valuable, then most likely you made a backup copy.
If not, then you can try to restore them through the system function – Restore Point. All other methods will require patience.

You need GridinSoft Anti-Malware to remove active system infections. The virus that encrypted your files is most likely still active and periodically runs a test for the ability to encrypt even more files. Also, these viruses install keyloggers and backdoors for further malicious actions (for example, theft of passwords, credit cards) often.
In this situation, you need to prepare the memory stick with a pre-installed Trojan Killer.
You can try to find a copy of an original file that was encrypted:
- Files you downloaded from the Internet that were encrypted and you can download again to get the original.
- Pictures that you shared with family and friends that they can just send back to you.
- Photos that you uploaded on social media or cloud services like Carbonite, OneDrive, iDrive, Google Drive, etc)
- Attachments in emails you sent or received and saved.
- Files on an older computer, flash drive, external drive, camera memory card, or iPhone where you transferred data to the infected computer.
Also, you can contact the following government fraud and scam sites to report this attack:
- In the United States: On Guard Online;
- In Canada: Canadian Anti-Fraud Centre;
- In the United Kingdom: Action Fraud;
- In Australia: SCAMwatch;
- In New Zealand: Consumer Affairs Scams;
- In France: Agence nationale de la sécurité des systèmes d’information;
- In Germany: Bundesamt für Sicherheit in der Informationstechnik;
- In Ireland: An Garda Síochána;
To report the attack, you can contact local executive boards. For instance, if you live in USA, you can have a talk with FBI Local field office, IC3 or Secret Service.
How сan I avoid ransomware attack?
W2tnk ransomware doesn’t have a superpower.
You can easily protect yourself from its injection in several easy steps :
- Ignore all emails from unknown mailboxes with a strange unknown address, or with content that has likely no connection to something you are waiting for (can you win in a lottery without taking part in it?). If the email subject is likely something you are waiting for, check carefully all elements of the suspicious letter. A fake email will surely contain a mistake.
- Do not use cracked or untrusted programs. Trojans are often distributed as a part of cracked software, possibly under the guise of “patch” which prevents the license check. But untrusted programs are very hard to distinguish from trustworthy software, because trojans may also have the functionality you need. You can try to find information about this program on the anti-malware forums, but the best solution is not to use such programs.
- And to be sure about the safety of the files you downloaded, use GridinSoft Anti-Malware. This program will surely be a perfect shield for your personal computer.
