What is Wesker ransomware?

Wesker ransomware is a cryptovirus that adds no extension to encrypted files and demands 0.75 Dash for the decryption tool

Wesker ransomwareWesker ransomware is a file locking threat that uses AES encryption for file encryption purposes

Wesker ransomware is a file locking malware that was first spotted mid-May 2019. The cryptovirus does encrypt data with the help AES cipher but does not append any extensions. Instead, the hex of the file is modified by adding WESKER_ENC mark at the end, which consequently prevents victims from opening pictures, music, video, and other personal data.

As soon as the encryption is complete, Wesker Encrypter ransomware drops a ransom message !!! INSTRUCTION_RNSMW !!!.txt which explains to users what to do next in order to regain access of all the encrypted files. Inside the note, victims are directed to the Tor browser link wesker7b27uikjn3.onion/index.php?6b1AAdbb9d737C529783cf7eec9703dA where cybercriminals demand 0.75 Dash[1] (which is approximately $100), and if the ransom is not paid within a week, the price is doubled.

Interestingly, Albert Wesker[2] is a captain of U.S. police team STARS from Capcom's Resident Evil series and is one of the main characters. Wesker Encrypter ransomware is not currently decryptable, although we provide alternative recovery methods at the end of this article.

Wesker ransomware is another dangerous ransom-demanding infection that was first discovered at the start of May this year. Its operating principle is the same – to encrypt files and demand money. However, things such as a unique ransom price and no identifiable appendix make the ransomware different from others of its kind.

There is a big variety of documents and files that can be touched and blocked by Wesker Encrypter ransomware. These components include Microsoft Word documents, Excel data, PowerPoint presentations, audio and video files, archives, etc. Once the data is locked, users are provided with this type of ransom-demanding message:

Wesker ransomware might include a big variety of damaging features that might not be recognized from the first view. However, these threats can not only encrypt targeted files but they also might inject other infections such as trojans or spyware into the computer system. This will just harden the elimination process.

Nevertheless, this cyber threat might be capable of eliminating Shadow Volume Copies of encrypted data to prevent users from trying to unblock their data. You need to immediately remove Wesker Encrypter ransomware from the infected computer system without postponing this process, otherwise, you will supposedly have to deal with unpleasant consequences.

Wesker ransomware removal is a very responsible thing to carry out so it should not be done on your own. We recommend downloading and installing a reputable computer tool such as ReimageIntego to scan the entire system and find all possible malware traces. Keep in mind that all infection sources need to be terminated, otherwise, the ransomware will return within the next computer reboot.

Distribution sources of ransomware cyber threats

According to cybersecurity experts from Virusai.lt,[3] ransomware infections can reach various operating systems, however, the most infected one is Windows. As more users have Windows computers, criminals mostly target this kind of OS. Ransomware infections are installed on the targeted machines by launching infectious executables.

These infected files come attached to spam email messages.[4] We recommend all users to stay careful and scan all received attachments with antivirus protection. If you do that, you will be warned about possible threats before opening the rogue message or file. Moreover, ransomware-related payload comes injected in suspicious hyperlinks that can be provided in the email message itself.

Last but not least, there is a big variety of unsafe websites lurking out in the cybersphere. Pages such as peer-to-peer ones often lack protection and are unsafe to visit. By clicking on them or downloading content that is posted there, you might accidentally start the installation of a ransomware infection or other type of malware.

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.

 

Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
