As usual the hackers behind the Viki virus make the victims pay a ransomware fee. Unlike some other popular malware of this type they do not specify a fixed sum. Instead the criminal operators have supplied a contact e-mail address hosted on freely hosted Gmail service. It is very likely that this is used as a relay and decoy for another email inbox.

Computer hackers use the popular tactic of evaluating the needed sum to restore the files based on their contents. If it contains private and sensitive information then a high fee may be quoted. Ransomware viruses like Viki almost exclusively request the money to be paid in the Bitcoin digital currency. The transactions are made anonymous and cannot be traced to a specific individual.

In addition the Viki ransomware virus deletes all found Shadow volume copies. This means that data recovery is impossible without the use of a quality solution.

Viki Virus Distribution Tactics

The collected Viki ransomware virus samples have been found to infect computer users via different strategies. One of the main ones is the use of phishing emails. They use social engineering tricks that make the targets infect themselves with the binary. Depending on the used template the Viki virus may be directly attached to the messages or linked in the body contents.

Hackers may also opt to use infected software installers or office documents. They contain the Viki ransomware in a covert way and resemble legitimate content. Such files can be found on hacked or hacker-controlled download sites and P2P networks like BitTorrent.

Advanced ransomware strains and payload droppers, as well as web redirect scripts can also lead to a Viki virus infection.
