It collects host identifiers (hostname, platform, architecture, kernel release, uid/gid, CPU count, memory) and internal network interface addresses, base64-encodes the payload, and POSTs it over plain HTTP to the hardcoded subdomain vml73pdk3ft3t434ssjycv4khbn2btzi.oastify.com — a Burp Collaborator (OAST) callback host used to confirm code execution on the installer. The package has no other functionality; its sole install-time effect is the outbound beacon carrying installer reconnaissance data to an attacker-controlled domain.\n","modified":"2026-09-14T17:30:06.154291443Z","published":"2026-09-14T16:44:27Z","database_specific":{"malicious-packages-origins":[{"import_time":"2026-09-14T17:15:20.7894485Z","modified_time":"2026-09-14T16:44:27Z","sha256":"cf3b4f18f9d98ad0792f96d750aef64b390ae6a516d948457d1e78b1d3242ab8","source":"amazon-inspector","versions":["1.0.0"],"id":"IN-MAL-2026-020025"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/os-info-meeb322k/v/1.0.0"}],"affected":[{"package":{"name":"os-info-meeb322k","ecosystem":"npm","purl":"pkg:npm/os-info-meeb322k"},"versions":["1.0.0"],"database_specific":{"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/os-info-meeb322k/MAL-2026-16149.json","cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"package_integrity":[{"hashes":{"sha1":"4d709506226e1f670312cd987a6a84f3bda182db","sha512_sri":"sha512-z5VEWcqF7T/hUaYOnv1Ek0Ri1Q8IbU12431U8rS4aSclAXzHgYm5taEYuoVsSPMU9/mj/Bb5pPKFPV7M/42oDQ=="},"filename":"os-info-meeb322k-1.0.0.tgz"}],"evidence_files":[{"sha256":"1d1f5e5f6b82627777336227669621baa5daeb3ba2c3a4f517a4de5533be8c5a","tlsh":"1b3153d406fa46303ab911c434979823daa1d1163a1ab8f9bcfc06c5dfce5d861727bd","path":"postinstall.js"}]}}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
