CALUM ransomware encryption process.
Once the virus gets into the system it immediately begins to encrypt files. The encryption process can be subdivided into two steps, that occurs one by one. At first, the virus looks for the files that can be encrypted in the all folders on the hard drive. it can encrypt only definite file formats, such as media files and documents, as it’s very difficult to encrypt all files on the computer. Then it begins to modify file structures and makes the unreadable. The result of it the new extension .id[*random*].[keysfordecryption@airmail.cc].Calum. The renaming of file doesn’t help and it requires to use file decryptor in order to restore them. That’s why the virus creates the ransom note, that’s called info.txt.
