What is Juwon ransomware? And how does it execute its attack?
Juwon ransomware is a data-encrypting malware discovered in the second week of January 2019 captured in its early variants. Based on its initial code analysis, this crypto-virus is developed by a hacker or a group known as Seojuwon. Since the captured samples of this ransomware are early versions, they do not contain any code or components other than the ransomware engine.
Once it executes its attack, Juwon ransomware will drop its malicious payload in the system. This malicious payload is the one that connects the system to a remote server controlled by the attackers and from this server, Juwon ransomware will download its other components and place them on system folders. It also allows the attackers to spy on victims and take control of the machine. Following the infiltration, Juwon ransomware employs a data gathering module used to collect information in the system. The collected information is then used for the stealth protection module. This module is the one that bypasses any security programs, sandbox environment and antivirus programs that could interfere with the attack. Once it finds these aforementioned programs, Juwon ransomware will disable or remove them from the system. After that, it starts the encryption using the AES cipher. It then opens a program window which contains the following content:
Sorry. It can not be accessed. To recover, you must enter your password or purchase a decryptor. The moment you close this program, your computer will be a fool. Seojuwon is a computer genius. Failure to enter the password within 24 hours will destroy the computer. Typing juwon will display a password hint. And when you give up, your computer is instantly destroyed.
