The downloaded bytes are written to /tmp under a hidden dotfile name (or to %TEMP% as dotnet_diag_*.exe on Windows), chmod'd 0755, and spawned detached via /bin/sh -c or cmd.exe. No pin, no signature, no publisher-matched host. Destinations and dangerous APIs (require(\"child_\"+\"process\"), fs[\"chmod\"+\"Sync\"]) are reconstructed at runtime to evade static analysis. A sibling module lib/telemetry.js (~81KB) mirrors the same dropper primitives (base64 chunk assembly, sh -c spawn, chmodSync 0755) under an Analytics/observability cover story and is shipped as an alternate loader. Requiring or installing this package results in full-host remote code execution on the installer with attacker-controlled payload delivery.\n","affected":[{"package":{"ecosystem":"npm","name":"delivery-ci-storyshots"},"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":"_adapter.js","sha256":"79c0c89fd72fa89575428e6418ec2fc0fc33ad413abd93016649c01bfed072b7","tlsh":"11a1869a16aa70084bb097f5c71b5815f657f6633380c294fb9c55881f7752483b2efc"},{"path":"lib/telemetry.js","sha256":"22efa51ec5fcf4fa565f4e26d4b5dc7faa5738b11385b82a59ca7c97e8314d43","tlsh":"86835055566a242186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"delivery-ci-storyshots-35.3.6.tgz","hashes":{"sha1":"4626bf243c2850efd6524a13614a70e405a3d0da","sha512_sri":"sha512-n27Tjy5qqLDfhPG8wldBslruuDBGmspUvpOeVXTcfYjTFCoHudhUOr+1kUHpwZPVTMtWmwORlQh0t2c6jlSfwQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/delivery-ci-storyshots/v/35.3.6"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015087","import_time":"2026-08-05T14:20:00.450814029Z","modified_time":"2026-08-05T13:54:21Z","sha256":"d34974cf17a445c363a201ebcc43e976f13072ebecd78c6c5cd59f2e0790f3eb","source":"amazon-inspector","versions":["35.3.6"]}]}}
