The North Korean risk actor often known as the Lazarus Group has been noticed leveraging a “web-based administrative platform” to supervise its command-and-control (C2) infrastructure, giving the adversary the flexibility to centrally supervise all elements of their campaigns.
“Each C2 server hosted a web-based administrative platform, built with a React application and a Node.js API,” SecurityScorecard’s STRIKE group mentioned in a brand new report shared with The Hacker Information. “This administrative layer was consistent across all the C2 servers analyzed, even as the attackers varied their payloads and obfuscation techniques to evade detection.”
The hidden framework has been described as a complete system and a hub that permits attackers to prepare and handle exfiltrated information, preserve oversight of their compromised hosts, and deal with payload supply.
The online-based admin panel has been recognized in reference to a provide chain assault marketing campaign dubbed Operation Phantom Circuit concentrating on the cryptocurrency sector and builders worldwide with trojanized variations of reliable software program packages that comprise backdoors.
The marketing campaign, which passed off between September 2024 and January 2025, is estimated to have claimed 233 victims the world over, with most of them recognized in Brazil, France, and India. In January alone, the exercise focused 110 distinctive victims in India.
The Lazarus Group has turn into one thing of a social engineering skilled, luring potential targets utilizing LinkedIn as an preliminary an infection vector below the guise of profitable job alternatives or a joint collaboration on crypto-related tasks.
The operation’s hyperlinks to Pyongyang stem from using Astrill VPN – which has beforehand been linked to the fraudulent info expertise (IT) employee scheme – and the invention of six distinct North Korean IP addresses which have been discovered initiating connections, which have been routed by Astrill VPN exit nodes and Oculus Proxy endpoints.
“The obfuscated visitors finally reached the C2 infrastructure, hosted on Stark Industries servers. These servers facilitated payload supply, sufferer administration, and information exfiltration,” SecurityScorecard mentioned.
Additional evaluation of the admin part has revealed that it permits the risk actors to view exfiltrated information from victims, in addition to search and filter of curiosity.
“By embedding obfuscated backdoors into legitimate software packages, Lazarus deceived users into executing compromised applications, enabling them to exfiltrate sensitive data and manage victims through command-and-control (C2) servers over port 1224,” the corporate mentioned.
“The campaign’s infrastructure leveraged hidden React-based web-admin panels and Node.js APIs for centralized management of stolen data, affecting over 233 victims worldwide. This exfiltrated data was traced back to Pyongyang, North Korea, through a layered network of Astrill VPNs and intermediate proxies.”
