{"id":"MAL-2026-16254","summary":"Malicious code in pulse-pwn-9f3a2 (npm)","details":"\n---\n_-= Per source details.

Any consumer that requires or imports this package in a browser-like context leaks the caller's session cookies and /profile response to an attacker-controlled collector. The destination is a third-party request-inspection service unrelated to any documented purpose of the package, and the exfiltration path fires on module load rather than through an explicit API call.\n","modified":"2026-09-17T15:30:05.792161606Z","published":"2026-09-17T14:42:28Z","database_specific":{"malicious-packages-origins":[{"versions":["1.0.0"],"id":"IN-MAL-2026-020131","import_time":"2026-09-17T15:18:28.827839222Z","modified_time":"2026-09-17T14:42:28Z","sha256":"f8086e23ce4b6ff1ca043ca8d9c83f384455e0baee3d06cd79e8a0d5d52c04e1","source":"amazon-inspector"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/pulse-pwn-9f3a2/v/1.0.0"}],"affected":[{"package":{"name":"pulse-pwn-9f3a2","ecosystem":"npm","purl":"pkg:npm/pulse-pwn-9f3a2"},"versions":["1.0.0"],"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":"19c022b7271cc8220c598004f7a9f41ee289e3009c26e22a891a63b40332013e901671","path":"index.js","sha256":"d1be27f0e21fb8b7a08154bf3571a3458ce21ab34df16481344436dc50abdf71"}],"package_integrity":[{"hashes":{"sha1":"b88104b0ec69c1f55f62b943e09f15206596be9f","sha512_sri":"sha512-C4ZgHvsoCCXRE1XVsCoh/23unyl636g6FdXZ+MO8rF09ye0inzHkvYhChHEJ1kdETCaA24d0p8Fr4TYSBDpy2w=="},"filename":"pulse-pwn-9f3a2-1.0.0.tgz"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/pulse-pwn-9f3a2/MAL-2026-16254.json"}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
