North Korean Group Adopts EtherHiding for Malware Campaign

🔐 Google Threat Intelligence has linked a campaign to UNC5342, a cluster tied to North Korea, that now uses EtherHiding to distribute malware via smart contracts on public blockchains such as BNB Smart Chain and Ethereum. The attackers lure developers through LinkedIn recruitment ruses, move conversations to Telegram or Discord, and deliver npm-package downloaders that chain into BeaverTail, JADESNOW, and the Python backdoor InvisibleFerret. By embedding payloads in on-chain contracts, the group turns blockchains into tamper-resistant dead-drops that are hard to takedown and easy to update, enabling sustained cryptocurrency theft and long-term espionage.

DPRK Actor UNC5342 Employs EtherHiding for Crypto Theft

🧩 GTIG reports that DPRK-linked UNC5342 has adopted EtherHiding, using smart contracts on public blockchains to store and deliver malicious JavaScript payloads. The actor leverages social engineering—fake recruiter lures and technical interviews—to deploy the JADESNOW downloader, which fetches and decrypts on-chain payloads and stages the Python backdoor INVISIBLEFERRET. Google recommends enterprise controls and Chrome management policies to disrupt this resilient, decentralized C2 method.

DPRK Hackers Adopt EtherHiding to Conceal Malware Campaigns

🔒 Google Threat Intelligence Group (GTIG) reports that a DPRK-aligned threat actor tracked as UNC5342 has employed EtherHiding since February to host and deliver malware via smart contracts on Ethereum and the BNB Smart Chain. Campaigns begin with fake technical interviews that trick developers into running a JavaScript downloader named JADESNOW, which fetches a JavaScript build of InvisibleFerret for in-memory espionage and credential theft. The method offers anonymity, takedown resistance, and low-cost, stealthy payload updates.
