Once, Krusop virus sneaks in your system, it scans every inch to locate the targeted files. With the allocation of files, the execution of mal intention begins. The disaster begins with file encryption by appending .krusop extension with filenames. It eventually makes the encrypted files unreadable!

As a result, blackmailing comes into picture! Cyber crooks demands hefty ransom in exchange of Krusop decrypter. The victims are asked to make the transaction in bitcoins – a crypto currency.

If in case, victim users fail to make the payment successfully, they are been threatened for permanent data loss. Hence, with the fear of losing the data, they get ready to pay any asked amount.

The ransom-demanding message is delivered to you in a text file – _readme.txt. It is basically a notification that informs you about the crypto virus attack.
