Officials at the US Department of Homeland Security (DHS) have issued another warning about North Korean malware, this time a new variant dubbed “Hoplight.”

The backdoor trojan malware is linked to the notorious Hidden Cobra group, also known as the Lazarus Group.

“This artifact is a malicious PE32 executable. When executed the malware will collect system information about the victim machine including OS version, volume information, and system time, as well as enumerate the system drives and partitions,” the alert warned.

“The malware is capable of the following functions: Read, Write, and Move Files; Enumerate System Drives; Create and Terminate Processes; Inject into Running Processes; Create, Start and Stop Services; Modify Registry Settings; Connect to a Remote Host; Upload and Download Files.”

The malware uses a public SSL certificate for secure communications from South Korean web giant Naver, and employs proxies to obfuscate its activity.

“The proxies have the ability to generate fake TLS handshake sessions using valid public SSL certificates, disguising network connections with remote malicious actors,” the report claimed.

U.S. Government Details ELECTRICFISH Malware Used by North Korea | SecurityWeek.Com
ELECTRICFISH is a command-line tool that accepts arguments for configuring the destination and source IPs and ports, a proxy IP, and a username and password for authenticating with a proxy server.

“The malware continuously attempts to reach out to the source and the designation system, which allows either side to initiate a funneling 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,” the malware report reads.
