Lokf ransomware virus

Lokf ransomware already penetrated hundreds of machines in different parts of the world via basic manner: fraud e-mails with viral attachments. Also, scammers use zero-day vulnerabilities to take control over the system, but major program companies quickly correct them. When infection is done, ransomware reviews the computer memory, determines the number of files to be cyphered and their approximate worth. At the moment, each modern virus knows how to encrypt audio, text, image and video information in all most used extensions. High attention is paid to business files, since medium and large companies are the key target for hackers. All software in the system will be untouched since hackers are interested only in information. The operation is carried out via well-known encryption algorithms, and it is so sophisticated that that it cannot be bruteforced. This is the ground for unbelievable efficiency of ransomware in recent years: common user, even having a fairly good experience in suchlike things, won't ever decrypt the data, and will have no way out except paying to scammers. The sole manner to get back the data is to find the scammer's site and retrieve the encryption keys. Also there's a chance to obtain the keys through defects in viruse's program code.

The knowledge of computers is very important in progressive world, since it helps customer to guard the machine from dangerous software. Unfortunately, 90% of customers comprehend the importance of computer knowledge only after ransomware infection. To shield yourself, you must keep in mind a three basic rules:

    • Heed to the dialog boxes. If the system is infected by Lokf, it will try to remove all copies of the files, to make the recovery impossible. However deleting of copies requires administrator rights and verification from the user. So, if you don't confirm changes from a suspicious program at the proper time, you will save the way to restore all lost data free of charge.
    • Attentively study your emails, especially those messages which have attached files. If you don't know who send the message and it is about winning any prize, a lost package or anything like that, this could be ransomware. You also should be attentive with business correspondence, particularly if you don't know the person who send it and not sure what's inside. It is OK to take an interest and read the message even if it's sent to the wrong address, but don't forget that a single click on the attached file may cost you a lot of headache, money and time.
    • Keep an eye on the condition of your workstation. It requires a lot of computing power to encode the information. When the virus is starting to operate, the machine slows down, and the encrypting process can be found in Process Manager. You can catch this event and unplug the system before files will be fully encrypted. This, in case of infection, will save some of your information.
