Remove LASAN Virus (+Decrypt .lasan files) – DRV Ransomware

LASAN – Ransomware

The LASAN stands for a ransomware-type infection. The infection comes from the DRV ransomware family. LASAN was elaborated particularly to encrypt all major file types. When the file is encrypted people are not able to use them. LASAN adds the “.lasan” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by LASAN, will be renamed into “myphoto.jpg.lasan“. As quickly as the encryption is finished, LASAN places a special text file into every folder containing the encrypted data.

The message given by LASAN text file requesting the ransom is definitely the same as the statements given by other ransomware virus representatives coming from the DRV family. It actually mentions that the information is encrypted which the only way to bring back it is to use a a special decryption key. Unfortunately, this is definitely true. The kind of cryptography mechanism used by LASAN is still not appropriately examined. Still, it is absolutely specific that each victim may be given the specific decryption key, which is absolutely unique. It is difficult to bring back the files without the key available.

Another trick of LASAN is that the victims cannot gain access to the key. The key is kept on a particular server run by the frauds connected with LASAN ransomware. To get the key and recover the important info people have to pay the ransom.

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

We strongly recommend that you do not contact these crooks and definitely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack LASAN ransomware and to recover the information data totally free. Thus, the just best decision is to recover the lost information from the available backup.
