How to remove WannaRen Ransomware

Tips for WannaRen Ransomware removal

Petrovic discovered WannaRen Ransomware is a ransomware type infection. It is designed to encrypt stored data and demand ransom payment for the decryption. During the encryption process, it appends the filenames of the encrypted files with .WannaRen extension. For example, it renames the file named 1.jpg as 1.jpg.WarrenRen. After the encryption process is completed, the ransomware displays a pop-up window that contains a ransom note. The text within this page is written in Chinese language.

On approximate translation, the ransom demanding message informs the victims that their data have been encrypted. The encrypted files include archives, executables, documents, images, audios, videos and other files. As per the note, the only way to recover the compromised data is to purchase a unique decryption key from the criminals. To get the key, the users are asked to pay 0.05 BTC, which is approximately equal to 340 USD at the current exchange rate. Further, it is written in the note that if the payment is not paid within the week the decryption will no longer be available. The note says, the users who are interested in purchasing the tool should have to write an email to the WannaRen Ransomware developers via the provided email address and provide the ID number given on it. At the last, the message warns the users that closing the pop-up window, deleting the malware or failing to prevent any antivirus program from doing so can lead to permanent data loss. The full text presented on the pop-up window is given below:

Unfortunately, in the case with any ransomware infection, the files decryption is not possible without the involvement of the crooks behind them. Such people manage to create a unique decryption key during the encryption processes and store that key on some remote server and then start blackmailing the users to pay the money. We recommend avoid paying/contacting to the crooks –the reason is that these people are typically there to scam the novice users. In other word, these people will never provide the decryption key even if all their demands are met.

The safest way to deal with this situation is to remove WannaRen Ransomware and then think of data recovery using data recovery alternatives. The malware removal is necessary to prevent it from further files encryptions and avoid various possible risks that can be caused by the WannaRen Ransomware due to the longer presence on the device. For its removal, use some reputable antivirus tool or follow manual malware removal guide provided below the post. After the virus removal process is done, you can consider about the data recovery. At current, there is no official decryption tool available for this ransomware and thus the only option left for you is to use any existing backup for the data recovery. However, data recovery tools that are nowadays designed with special functionality added can help you in recovering the damaged or locked files to the device.

How did ransomware infect my computer?

Spam campaigns, Trojans, dubious software download channels, fake software updates and unofficial software activation tools are some common channels that lead ransomware infection. In scam email campaigns, cyber criminals send various emails that contain attachments or web links, if opened- the attached/downloaded files infect computers with malware. Trojans are malicious programs that cause additional installation of malware. Third party downloaders, free file hosting websites, p2p networks, and etc spread malware by presenting it as legit software. Fake software updaters infect systems by exploiting bugs, flaws of already installed, outdated software or directly download malware instead of providing any software upadtes. Cracking tools infect the devices by supposedly providing activation for paid software.

How to protect yourself from ransomware infections?

Do not open any irrelevant attachments or the emails having unknown senders’ addresses. Use official websites and direct download links for any software download. Avoid using any untrustworthy sources or tools mentioned above.  Rely on those tools/functions from official software developers for any software updating and activation. For betterment, employ some reputable antivirus tool that provides adequate protection to the device.
