Pcqq Virus – Details

Pcqq is a harmful software functioning as common ransomware. Michael Gillespie, the well-known virus researcher, very first discovered this new name in the DJVU ransomware family.

Pcqq was developed for the sole function to encrypt all popular file types. Rationally, as quickly as the file encryption is effectively achieved, the users are not able to get access to them. Pcqq virus includes its own “.pcqq” to all the encrypted files. For instance, the file “price_list.xls”, when modified by Pcqq, will be entitled as “price_list.xls.pcqq”. Once the encryption is achieved, Pcqq puts its own distinct text document (_readme.txt) into all the folders that keep the encrypted files.

The message specified by document requesting the random os really comparable to the notifications provided by other ransomware threats belonging to the DJVU family. The caution generally indicates that the data has been encrypted and the only service to get access to it is to use a distinct standalone key. Regretfully, this statement is absolutely real.

The technique to secure the files used by Pcqq is not totally looked into. However, there is no doubt that each computer system owner may be released an unique decryption key, which is absolutely unique. It is exceptionally hard to recover the data without the appropriate key in location.

“Don’t worry, you can return all your files!”, from text file message:

One more peculiarity of the Pcqq virus is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have actually launched the Pcqq virus into the internet. In order to acquire the key and restore the crucial information, the users are told to connect with the frauds through email or by telegram and to pay the ransom in the amount of $980.

The message also states that individuals must get in touch with the Pcqq authors within 72 hours upon the moment of the information encryption. The alert suggests that by doing so the people will obtain a 50% discount rate, for that reason, the ransom quantity drops down to $490.
