MAL-2026-17263 Malicious code in @hrmony/kit (npm)

On require/import, index.js contacts the EC2 Instance Metadata Service at 169.254.169.254 using an IMDSv2 token, enumerates the instance's IAM role security-credentials (including temporary AWS access key, secret, and session token), enumerates every entry in process.env, and recursively reads /var/run/secrets/ (Kubernetes projected service-account tokens and mounted secrets). The collected data is POSTed to the hardcoded endpoint https://hrnmn.dd.h4x.tv/save_instance_info_index. package.json also declares a preinstall hook (node scripts/check_setup.mjs) intended to run a sibling variant of the same payload (scripts/check-setup.mjs) that exfiltrates to https://hrnmn.dd.h4x.tv/save_instance_info_hook; a filename hyphen/underscore mismatch appears to prevent that lifecycle path from firing, but the payload is present in the tarball. The package exports no functional API — index.js contains only the exfiltration code, and package.json metadata (description 'bip bop I get your sip sop', author 'kuhuna') is a cover story. The.h4x.tv destination is unrelated to any legitimate publisher.
