Malicious code in delivery-ci-storyshots (npm)
--- _-= Per source details.

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.
