Cybersecurity researchers have discovered a cluster of seven malicious npm packages targeting the Vite frontend tooling ecosystem as part of a software supply chain attack.
The malicious package campaign, codenamed ViteVenom by Checkmarx, marks an expansion of ChainVeil, which was observed using an "unprecedented" four-tier blockchain-based command-and-control (C2) infrastructure spanning Tron, Aptos, and Binance Smart Chain to deliver a remote access trojan (RAT) capable reverse shell, credential harvesting, file exfiltration, and persistent backdoor injection.
"This tactic makes disabling or destroying the C2 infrastructure extremely difficult," Checkmarx researcher Pavan Gudimalla said in an analysis published last month. The activity has been attributed to a threat actor named SuccessKey, with evidence of malicious activity detected as far back as February 27, 2026, when cryptocurrency wallets linked to ViteVenom were activated.
While the typosquats published to npm in connection with ChainVeil masqueraded as libraries for Tailwind, Sass, ORM, and rate-limiting tools, the latest iteration specifically focuses on developers building applications using the Vite JavaScript and frontend build tool.
