A sibling postinstall.js enumerates the installer's `~/.ssh` directory and POSTs the contents along with username and platform to a hardcoded remote host at 124.221.154.135:443/post. The declared purpose is a trivial date formatter, which has no legitimate need to read SSH material, enumerate internal networks, or contact OAST infrastructure.\n","affected":[{"package":{"ecosystem":"npm","name":"simple-date-formatter-new-8"},"versions":["1.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"package.json","sha256":"c0a1ff88d79aef5d0d7d5adc8962ddd7e32c13710c23be2a5c077a47b29da0ba","tlsh":"0221bc54e1209c33cbd98a99ce460a87ae5f984f5dfa3d88c4c34f7cd2496a610f92a5"},{"path":"postinstall.js","sha256":"f2be6940c08d36a7f1ce83d5fe16fefd8c14edda5d124e0f6406725beb5020ef","tlsh":"273165d558f9cd3007778685639b91263102fe13650ee940f3c807a51fe9a5449f2dee"}],"package_integrity":[{"filename":"simple-date-formatter-new-8-1.0.0.tgz","hashes":{"sha1":"b2f143ce50f44899f68c2efbc2f62bf002e681d0","sha512_sri":"sha512-8A0eoUyP8eN9I0lgyfqPYDE0DACnnefoKRzg8FrEkYGnwkzToAvczSeS92vWChDcocMMY6GapbWa0b/aw5HFlA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/simple-date-formatter-new-8/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-014422","import_time":"2026-08-05T09:28:09.367240758Z","modified_time":"2026-08-05T08:48:09Z","sha256":"4f0bf9e4040cf2940b0ca9a9e5cea7def2c660925afd0ba959ed69d28ca007b7","source":"amazon-inspector","versions":["1.0.0"]}]}}
