Paas – General Info
Paas is a destructive software application functioning as typical ransomware. Michael Gillespie, the well-known malware researcher, very first found this new name in the DJVU ransomware family.
Paas was created for the sole purpose to encrypt all popular file types. Rationally, as soon as the encryption is effectively achieved, the users are unable to get access to them. Paas ransomware includes its own “.paas” to all the encrypted data. For example, the file “price_list.xls”, when crypted by Paas, will be titled as “price_list.xls.paas”. As soon as the file encryption is accomplished, Paas puts its own unique text document (_readme.txt) into all the folders that store the encrypted files.
The alert mentioned by _readme.txt asking for the random os really comparable to the notices provided by other ransomware threats coming from the DJVU family. The caution basically indicates that the information has been encrypted and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely real.
The technique to secure the files utilized by Paas is not completely researched. However, there is no doubt that each computer system owner may be issued an unique decryption key, which is definitely unique. It is very difficult to recuperate the data without the appropriate key in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Paas ransomware is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the scoundrels who have actually introduced the Paas infection into the web. In order to obtain the key and bring back the essential information, the users are told to contact the frauds via email or by telegram and to pay the ransom in the amount of $980.
The message also states that individuals must contact the Paas authors within 72 hours upon the minute 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 falls to $490.
No matter what the amount of the ransom is, we strongly encourage that you do not pay the ransom. There is no guarantee that these online scoundrels will keep their guarantees, so they might not care at all what the victims feel about the file encryption, even when the amount of the ransom is gotten into their accounts. Hence, paying ransom typically does not result in a successful recovery. So, the users might simply lose their money for absolutely nothing.
Likewise, we prompt you not to call the frauds as they advise. Do not transfer loan into their wallets. There are no applications that could crack the Paas virus or bring back the data at no cost. For that reason, the only appropriate choice is to restore the data from possible backups (if offered).
