antsrcsrctest@1.0.0(npm) is a supply-chain credential/environment stealer disguised as a date utility (index.js exports a benign formatDate()).A
preinstallhook (node preinstall.js) runs automatically onnpm install, before import. It fingerprints host/container, runs recon (id,whoami,ps aux) via child_process.execSync, queries the cloud instance-metadata servicehttp://100.100.100.200/latest/meta-data/ram/security-credentials/(Alibaba Cloud IMDS → temporary RAM/IAM credentials), dumps the entireprocess.env, and exfiltrates everything via HTTP POST to the hardcoded IPhttp://101.35.44.248(paths / and /env). The name targets an internalantsrc*namespace (dependency confusion).Detected independently by codelake Research from the live npm feed on 2026-07-09; still live on npm and not in OSV/GHSA at time of reporting.
