Vulnerability: Weak Hardcoded Credentials
Vuln ID: MVID-2022-0625
Description: The malware listens on TCP port 6210 and authentication is required. However, the backdoor accepts any USER name for authentication and the password "R-M" is weak and hardcoded within the PE file. Unpacking the UPX packed executable, easily reveals the cleartext hardcoded password.
