Bufas ransomware virus

Bufas is the undesired program infecting workstations mainly with help of Trojans and scam e-mails.

After penetration, the virus reviews the computer memory, defines the quantity of folders for encryption and their approximate price. Currently, any new virus can encrypt text, video, image and audio information in all known formats. Extra attention is paid to businesslike files, since medium and large companies are the key target for fraudsters. Ransomware encrypts only files with information, and does not affect the programs, so that the victim can pay the ransom with help of his PC. The process is carried out through world-known AES and RSA algorithms, and it is so sophisticated that that decryption of data without a key is impossible. Such complexity creates base for such an incredible success of this sort of viruses in last years: usual user, even if he has a very good experience in suchlike things, won't ever be able to restore the data, and will have to pay ransom. The sole manner to recover files is to hack the scammer's site and withdraw the encryption keys.

It's sad to say, but most people understand the significance of computer knowledge just when ransomware penetrates their computers. It's very easy to minimize the chances of getting ransomware if you'll follow these advices:

    • Keep an eye on the status of your machine. It takes a lot of CPU power to encrypt the information. If you see a sudden decline in system capacity or notice a unwanted string in the Process Manager, you should shut down the PC, start it in safe mode, and scan for malware. This, in case of penetration, will guard some of your files.
    • Heed to the pop-up windows. One of the basic manners of information recovery is the restoration from Shadow Copies, and fraudsters have included the elimination of those copies into the default features of viruses. Anyway, deletion of shadow copies needs administrator rights and acceptance from the user. If you'll think for a moment before accepting the dialogue box, it may save your files and your money.
    • Carefully study your mailbox, especially those messages which have files attached to them. If you don't know the person who send the message and it tells about earning any prize, a lost parcel or something like that, this might be ransomware. Also you should keep an eye on business-related messages, especially if you don't know the sender and not sure what's inside. lawsuits, summaries, Bills for services or goods, complaints and similar sensitive information do not come without warning, and the receiver should know the person who sent it. Otherwise, it is a fraud.
