Kovasoh Ransomware is the brand-new addition to the ever-growing & infamous Stop Djvu Ransomware Family. Alike other variants it propagates its infection through various spread techniques.
It enters the system stealthily & does not require any manual help to install on the PC. Upon installation, it searches the entire system for certain targeted file extensions & types. When located, it employs highly-complex Encryption Algorithms to encrypt the files & generate a private unique key for each infected system. These keys are stored on the server controlled by hackers.
The encrypted files are renamed & .Kovasoh Extension is added as a suffix to the file names.
A file named image.jpg might be renamed as “image.jpg.kovasoh” after the encryption.
All the .kovasoh files are instantly made inaccessible due to significant modifications in their codes.
Some of the file extensions that .Kovasoh virus Ransomware is capable of encrypting are mentioned below:
A ransom demanding banner appears on the screen every time an encrypted file is accessed. This note is a text document named “_readme.txt”. The note contains the ransom amount & instructions on how victims can contact the hackers.
