The Teslarvng mean a ransomware-type infection. The infection comes from the Ouroboros ransomware family. Teslarvng was elaborated particularly to encrypt all major file types. When the file is encrypted people are not able to use them. Teslarvng adds the “.[de-crypt@foxmail.com].teslarvng” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Teslarvng, will be renamed into “myphoto.jpg.[de-crypt@foxmail.com].teslarvng“. As soon as the encryption is completed, Teslarvng places a special text file into every folder containing the encrypted data.

The message given by Teslarvng text file asking for the ransom is definitely the like the statements given by other ransomware representatives belonging to the Ouroboros clan. It actually mentions that the info is encrypted which the only way to restore it is to use a an unique decryption key. Regretfully, this is definitely true. The kind of cryptography mechanism used by Teslarvng is still not appropriately examined. Still, it is absolutely particular that each victim may be given the specific decryption key, which is absolutely distinct. It is impossible to bring back the files without the key available.

Another technique of Teslarvng is that the victims cannot get to the key. The key is saved on a particular server run by the frauds associated with Teslarvng ransomware. To get the key and recover the important information people need to pay the ransom.

Nevertheless, regardless of the requested quantity, people should keep away from paying the virus. Cyber frauds are unfair, so they tend to completely disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom usually does not provide any positive result and people just lose their money for absolutely nothing.

It is said to admit that there are no utilities able to crack Teslarvng ransomware and to recover the information data free of charge. Thus, the only right decision is to recover the lost data from the available backup.
