How to remove 7even Security Ransomware and decrypt your files

What is 7even Security Ransomware

Recent forum discussions have shown some users got a ransomware attack on PCs connected to NAS (Network Attached Storage). The virus encrypts NAS-stored data, wraps it in archives, and puts up a password on them. This prevents victims from accessing artificially created archives and viewing what files have been affected by the infection. Unlike many other ransomware infections, 7even Security does not use any extension to modify file appearance. It does though create a text note called Please Read Me !!!.txt containing instructionы on how to return the encrypted data.

According to the above-mentioned note, cybercriminals demand 0.04 BTC for file decryption. This amount has to be sent to the attached crypto address. Victims are also guided to notify swindlers about successful payment through their e-mail address (team.seven@zohomail.eu) and include a personal ID. Should victims refuse or ignore to pay the demanded ransom, cybercrooks threaten to sell all important data to interested figures. Because the infection is recent, there is not a lot of information on whether files can be decrypted or not. At the moment, the only best way to recover data completely is via backup copies of files. Otherwise, attempts to decrypt data alone are likely to turn in permanent damage of data and therefore loss. Since this iteration of 7even Security is new, we advise you to keep track of further discussions and updates related to this infection on this forum. You can use our guide to delete the infection and explore some third-party tools generally used in recovering data.
