CILLA – Ransomware
The CILLA mean a ransomware-type infection. The virus comes from the GlobeImposter ransomware family. CILLA was elaborated specifically to encrypt all major file types. Once the file is encrypted people are unable to use them. CILLA adds the “.CILLA” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by CILLA, will be renamed into “myphoto.jpg.CILLA“. As quickly as the encryption is completed, CILLA places a special text file into every folder containing the encrypted data.The message given by CILLA text file requesting for the ransom is definitely the like the statements given by other ransomware virus representatives coming from the GlobeImposter type. It literally points out that the information is encrypted and that the only way to bring back it is to use a an unique decryption key. Unfortunately, this is definitely true. The kind of cryptography mechanism used by CILLA is still not properly examined. Still, it is definitely specific that each victim might be given the specific decryption key, which is absolutely unique. It is impossible to bring back the files without the key available.
Another trick of CILLA is that the victims cannot access to the key. The key is stored on a specific server run by the frauds related to CILLA ransomware. To get the key and recover the important info people have to pay the ransom.
CILLA encrypted your documents, but that might not be the only damage done to you. The ransomware might still be hidingon your computer. To identify whether this holds true, we suggest downloading GridinSoft Anti-Malware.

However, regardless of the asked for quantity, people should keep away from paying the virus. Cyber frauds are not fair, so they tend to completely ignore what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom generally does not give any positive result and people just waste their money for nothing.
