ViiperWare ransomware had penetrated thousands of computers around the world with help of basic method: fraud messages with viral attachments. Occasionally scammers use zero-day vulnerabilities to get into the computer, but major software developers quickly correct them. When infection takes place, ViiperWare inspects the hard disc, determines the quantity of folders to be encrypted and their approximate worth. Nowadays, each modern virus knows how to cypher audio, text, video and image information in all known extensions. ViiperWare corrupts all files, but the ones that could be business documents go first. Ransomware encrypts only files with information, and doesn't touch the programs, so that the victim can use his machine to pay the ransom. Encryption is executed with the help of famous encryption algorithms, and it is so complicated that that decipherment of files without a key is impossible. This is the root for unbelievable efficiency of this type of viruses in recent years: common user, even if he has a fairly high experience in suchlike things, will never be able to restore the files, and will have to pay ransom. The single way to restore files is to find the scammer's site and obtain the master key. Some skilled hackers can retrieve encryption keys via flaws in viruse's program code.

For ransomware it's very relevant, as, unlike normal malicious software, after removing ransomware from the PC, the effects of its doings do not vanish anywhere. It's very easy to reduce the chances of getting encrypting virus if you'll follow these principles:

    • Heed to the dialog boxes. If the workstation is infected by ViiperWare, it will seek to delete the shadow copies of your data, to make the recovery impossible. Anyway, deleting of copies requires administrator rights and your acceptance. The moment of thinking before verifying the changes might save your data and your money.
    • Keep an eye on the performance of your PC. It requires a big part of computing power to encode the data. When the ransomware starts to work, the PC slows down, and the encrypting process can be found in Process Manager. You may anticipate this moment and switch off the PC before data will be fully encoded. Surely, the certain amount of files will be damaged, but you will protect the rest of them.
    • Carefully study your e-mails, specifically those messages which have attached files. The #1 pattern of scam letters is the story about prize winning or parcel receiving. The second most popular type of fraud letters is a "business letters". Invoices for goods and services, lawsuits, claims, summaries and similar important files don't be sent accidentally, and you, as a minimum, should know the person who sent it.
