Malicious code in @hrmony/hyper-json-builder (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (d8139053048172994cadd0251ef74e5104c489dcb4f0448153ea9342b3feb707) On module load, index.js performs top-level fetch to a hardcoded attacker-controlled endpoint at https://hrnmn.dd.h4x.tv/save_instance_info_from_pkge_hrmony_hyper-json-builder and triggers two credential-harvest routines.

The destination path embeds this package's own name, indicating targeted exfiltration keyed to installations of this package. The package.json also declares an unpinned dependency @hrmony/kit-5 ^1.0.0 under the same scope that is not imported by the shipped code. ## Source: ghsa-malware (08fe204e5637fe696905f683edb7cba0c44df4ca14cbd809b3884f149d5dd90a) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guar
