WanaCry4 is a new variant of CryptoWire. Nevertheless, it uses the name of WannaCry; they are not related. This recent cyber threat is an open-source ransomware that is executed from WanaCry6.4.exe.

According to the latest research data, the WanaCry4 virus seems to use AES encryption algorithm and append .encrypted file extension. Malware renames files by following this pattern :[original-filename].encrypted[extension].

Following data encryption, WanaCry4 ransomware delivers a program window that informs about encrypted files and notes that the only way to get back access to them is to pay $1000 in Bitcoins within 72 hours. To obtain the virtual currency, victims have to click “Buy Bitcoins: button and follow the instructions there.

Once the transaction is made, they have to contact authors of the ransomware via email shadowbroker_1@protonmail.com. However, you may never receive a decryption key from them. Therefore, you should not risk loosing your money.

Instead of paying the ransom, obtain a reputable antivirus or malware elimination software, such as FortectIntego or SpyHunter 5Combo Cleaner. It will help to remove WanaCry4 from the PC safely.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
