The downloaded payload is written to /var/tmp (or the Windows TEMP directory) under a disguised name resembling dotnet_diag_*.exe /.cache_*, chmodded to 0755, and spawned detached via /bin/sh -c '<file> &' or cmd /c start with stdio ignored. Destination hosts are assembled from split string fragments (e.g. [\"oob-worker.cf\",\"103-070\",\".worker\",\"s.\",\"de\",\"v\"].join(\"\")) and child_process / chmodSync are required via string concatenation (require(\"child_\" + \"process\"), fs[\"chmod\" + \"Sync\"]) to evade static URL and API scanning. The same download-then-execute chain is duplicated in lib/telemetry.js (81KB). There is no version pinning, no hash or signature verification, and the destinations are unrelated to a UI notification library.\n","affected":[{"package":{"ecosystem":"npm","name":"devplatform-ui-notification"},"versions":["35.3.6"],"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":"_compat.js","sha256":"fc643a35b2bc4ca51a27763a2ab119fbe34f76c3d9490be5b633e2e5afbbac33","tlsh":"3ea1826a1666711887b09be4c6175416f55bf26373809294fb9c69881ff312482b2efc"},{"path":"lib/telemetry.js","sha256":"adef07be70415f31552d0e492428697a508d9d149a24a63cb52c2a0ea3bb81e0","tlsh":"46835055566a242186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"devplatform-ui-notification-35.3.6.tgz","hashes":{"sha1":"e92f4080ef33d8f07e9d53d314565bb7cb2e8bcd","sha512_sri":"sha512-vfZ/61mgB2P3Bmx3ugdTDGx+mUBXMpNoh46Piy6OUb8dD0P/m3I7RhV1W5/Slihox2XhDHOLB1OJN2N1w/eaeQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/devplatform-ui-notification/v/35.3.6"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015719","import_time":"2026-08-05T16:13:35.870731798Z","modified_time":"2026-08-05T15:29:33Z","sha256":"74230ed898152bc75d702938fcac9bd53e13ff7100120b44c5944bb8226225f7","source":"amazon-inspector","versions":["35.3.6"]}]}}
