Obliterate Jokeroo Ransomware (Crypto-Malware/Ransomware)

What is Jokeroo ransomware? And how does it execute its attack?

Jokeroo ransomware is a new “Ransomware-as-a-Service” or RaaS file-encrypting virus discovered recently. Although there are no reported victims yet, it is currently being promoted on underground hacking sites as well as on Twitter that allows cyber criminals to allegedly gain access to a fully functional ransomware and payment server. According to security experts, creators of Jokeroo ransomware first promoted this RaaS as a GandCrab Ransomware RaaS on the underground hacking forum at Exoloit.in. Soon after that, its creators changed the name to Jokeroo RaaS for some reason. Since then, its creators has begun promoting it on Twitter claiming that they have nothing to do with GandCrab ransomware. The creators of this crypto-virus promotes it with the following statement:

Jokeroo ransomware is written in the C++ programming language using WinAPI. According to the cyber crooks behind this threat, Jokeroo ransomware can removes all static detections of security programs to prevent them from interrupting the attack. It encrypt all the files in a targeted computer using a combination of the AES 256 and RSA 2048 encryption algorithm except for the system files. It uses AES 256 cipher for file encryption while it uses RSA 2048 to encrypt the decryption key. It also modifies the Windows Registry so that every time you start your computer, it will automatically start searching and encrypting new files as well as removable media. At the time of writing, Jokeroo ransomware is yet to be decrypted by malware experts so there is no free decryption tool available.
