The dangers of Rokku virus

Rokku virus is another cyber criminals’ creation, deemed by security experts as extremely dangerous. It is ransom-based program which stealthily enters the victims’ computers and encrypt the containing files. You may have heard of such notorious programs as Locky virus, CryptoLocker and CryptoWall, which have already infected hundreds of thousands of computers all across the world. Rokku works virtually by the same principle as the mentioned well-developed and widespread viruses. It is spread through spam emails, as PDF, picture or some other attachment file, posing as an important document, featuring some important-looking. If the user is tricked by the emails deceptive information and downloads the infected file, the Rokku virus is unleashed and begins its malicious processes on the victim’s computer.

Rokku bears its name of the file extension .rokku, which replaces the regular ones after the files are encrypted. This virus can lock tour regular photo, video files, documents, archives and other data you store on your computer. To achieve that, it uses a very complex RSA-3072 algorithm, which cannot be unlocked without a decryption key which is stored on some remote server out of the victim’s reach. After the files are encrypted the virus creates .txt or HTML file named README_HOW_TO_UNLOCK.TXT in which the victim can find the information about what happened to the PC and instructions on how to unlock the files. To retrieve the data, you must purchase the decryption the virus creators. This is how this fraudulent profit-making technique earns its name as a ransom-based virus. The ransom Rokku demands for the decryption key is not extremely large, compared, for instance with Locky virus, which has swindled over $17,000 from one unlucky hospital in Hollywood. You may be granted access to the file decryptor for only 0,2408 BTC virtual money, which equals around $100. However, it is not advisable to purchase anything from these cyber crooks because you might be scammed and lose not only your files but your money as well. What is more, you also risk contaminating your system with even more viruses if you decide to visit the suggested zvnvp2rhe3ljwf2m.onion website, since it can only be accessed through the anonymous Tor network, favoured by hackers, scammers and other internet criminals. If you are not willing to pay the ransom and rather keep your computer’s system healthy, you should remove Rokku virus from your computer as soon as possible. To delete the virus, please use reputable antivirus tools like Reimage to ensure the most effective removal.

How can this virus hijack your computer?

As we already mentioned, this virus spreads through the infected email attachments, so you have to be careful when opening newly received emails. Especially, look out for emails from unknown senders, possibly containing some spelling mistakes or other unusual features. If you have accidentally downloaded this malicious virus, you must remove it ASAP before it encrypts all of your files. However, it is rather difficult to notice it infiltrating the system. You may notice minor changes in computer’s speed, but apart from that, the virus makes sure that the encryption process remains stealthy. The only way to really ensure the safety of your files is to keep a backup of your files and store them in some external storage. However, we must warn you not to connect your external storage drives to the computer until you take care of the complete Rokku removal from the system because this virus may also be capable of infiltrating and locking the files on these platforms as well. So, the key methods to keep your files safe is to be careful with new suspicious emails and keeping backups of your files.
