The tarball additionally ships postinstall.js containing getSSHKeys(), which reads ~/.ssh from the installer's home directory along with username/platform metadata and POSTs the payload over HTTPS to a hardcoded bare IP 124.221.154.135:443/post. Installing the package runs the lifecycle exfiltration automatically; the SSH-key harvester is bundled dropper code aligned with the same intent. The trivial 'date formatter' name and the presence of a placeholder collector indicate a PoC/typosquat stub in an ongoing credential-theft campaign.\n","state":0,"publishedAt":"2026-09-24T13:16:33+00:00","modifiedAt":"2026-09-24T13:30:04.6047056+00:00","affected":[{"ecosystem":"npm","name":"simple-date-formatter-new-15","ranges":[],"versions":["1.0.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/simple-date-formatter-new-15/v/1.0.0"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17161","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17161","identifiers":["MAL-2026-17161"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
