Tirp was created for the sole function to encrypt all popular file types. Rationally, as quickly as the file encryption is effectively accomplished, the users are unable to get access to them. Tirp ransomware adds its own “.tirp” to all the encrypted data. For instance, the file “price_list.xls”, when modified by Tirp, will be entitled as “price_list.xls.tirp”. When the file encryption is accomplished, Tirp puts its own distinct text document (_readme.txt) into all the folders that keep the encrypted files.
The alert stated by _readme.txt requesting for the random os really similar to the notices offered by other ransomware risks coming from the DJVU family. The caution essentially indicates that the information has been encrypted and the only solution to get access to it is to use a distinct standalone key. Regretfully, this statement is absolutely true.
The approach to encrypt the files utilized by Tirp is not completely investigated. However, there is no doubt that each computer owner may be provided an unique decryption key, which is definitely special. It is incredibly hard to recuperate the data without the proper type in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Tirp infection 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 criminals who have actually introduced the Tirp infection into the world wide web. In order to get the key and bring back the essential data, the users are told to connect with the scams by means of e-mail or by telegram and to pay the ransom in the amount of $980.
The message also says that the people need to contact the Tirp authors within 72 hours upon the moment of the information encryption. The alert indicates that by doing so individuals will obtain a 50% discount rate, therefore, the ransom amount drops down to $490.

For this reason, paying ransom often does not result in a successful healing. So, the users might merely lose their money for absolutely nothing.

There are no applications that could split the Tirp virus or bring back the data at no cost. For that reason, the only appropriate decision is to restore the information from possible backups (if readily available).
