What is Kali ransomware? And how does it execute its attack?
Kali ransomware is a file-locking malware discovered recently. It extorts users into paying $500 in BTC in exchange for file recovery. It uses the AES 256 encryption algorithm in encrypting its targeted files. Once its malicious payload is activated in a targeted system, it starts to execute its attack by establishing a connection to a remote Command and Control server controlled by the attackers.
After it establishes a connection, Kali ransomware will download its malicious components from this remote server and places them to system folders. This allows the crypto-malware to control system processes. It then employs a data gathering module which is used to gather information from the infected computer. The harvested data will then be used for the next module called stealth protection used to scan digital signatures of security and antivirus programs installed in the system. Once it finds these programs, it either disables them or completely removes them from the computer to keep them from interfering with the attack. Moreover, Kali ransomware also alters some registry keys and sub-keys in the Windows Registry which allows it to run on every system startup automatically. Once all the system changes are applied, it starts encrypting its targeted files using the AES 256 encryption algorithm. Following data encryption, it appends the .kali extension to every file affected and releases a text file named “HOW TO DECRYPT FILES.txt” which contains the following message:
“ATTENTION ! ! !
