The North Korean APT group Hidden Cobra is using new variants of malware, dubbed ELECTRICFISH and BADCALL.
ELECTRICFISH:
The malware continuously attempts to reach out to the source and the designation system, which allows either side to initiate a tunneling session. The malware can be configured with a proxy server/port and proxy username and password. This feature allows connectivity to a system sitting inside of a proxy server, which allows the actor to bypass the compromised system’s required authentication to reach outside of the network.
BADCALL:
The sample files discovered for BADCALL variant are 32-bit Windows executable files that function as proxy servers and implement a “Fake TLS”.
Another Android Package Kit (APK) file designed to run on Android platforms is also found, that works as a fully functioning Remote Access Tool (RAT).
