The package name is a random keyboard-mash string with no documented purpose, and the only on-install behavior is the outbound beacon to an anonymous ephemeral webhook endpoint controlled by whoever created the webhook.site token.\n","modified":"2026-09-23T02:00:06.973284919Z","published":"2026-09-23T01:36:34Z","database_specific":{"malicious-packages-origins":[{"versions":["99.9.9"],"id":"IN-MAL-2026-020322","import_time":"2026-09-23T01:50:18.729889547Z","modified_time":"2026-09-23T01:36:34Z","sha256":"4845639223c486cf2d33751ad950cea4c7f70401877929d25c36e7d07655d820","source":"amazon-inspector"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/efhthrthrthregerht/v/99.9.9"}],"affected":[{"package":{"name":"efhthrthrthregerht","ecosystem":"npm","purl":"pkg:npm/efhthrthrthregerht"},"versions":["99.9.9"],"database_specific":{"cwes":[{"name":"Embedded Malicious Code","cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature."}],"indicators":{"evidence_files":[{"tlsh":"ac11cee58cab10100eb177b14c024805f7225722b51a9781b9bcc19d2fa69a5a271eec","path":"index.js","sha256":"a07fd09c2dccd9dcbe917ab7def77cfff55b6f6ea89ab4d6422de1542d12ca1f"}],"package_integrity":[{"hashes":{"sha1":"f2ddb8db11678f5288f77d5184c22814d04da47a","sha512_sri":"sha512-YgCWjWp4Bkx43ryQmiLMWXm+wHfo1sgFGe0bpZQOqhsy427JFg4rTCQrmyDh/yt+su5SLqvWln4IXAeds5AsIw=="},"filename":"efhthrthrthregerht-99.9.9.tgz"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/efhthrthrthregerht/MAL-2026-16436.json"}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
