OpenSSF/OSV advisory MAL-2026-6371 confirms this npm version as malicious. On `npm install`, the package's `preinstall` lifecycle hook runs `node index.js`, which collects host identity (`os.hostname()`, `os.userInfo()`, homedir, DNS servers, cwd) and reads the installer's `/etc/passwd` and `/etc/hosts`, then HTTPS POSTs the combined payload to `ltiyq4zyhrs88zgp5lef9hbec5i46uuj.oastify.com` — a Burp Collaborator (OAST) subdomain controlled by the package publisher...

Summary
Malicious code in llm-traces-app (npm)
Details
On `npm install`, the package's `preinstall` lifecycle hook runs `node index.js`, which collects host identity (`os.hostname()`, `os.userInfo()`, homedir, DNS servers, cwd) and reads the installer's `/etc/passwd` and `/etc/hosts`, then HTTPS POSTs the combined payload to `ltiyq4zyhrs88zgp5lef9hbec5i46uuj.oastify.com` — a Burp Collaborator (OAST) subdomain controlled by the package publisher. The exfiltration fires automatically on default install with no user interaction. Reading `/etc/passwd` enumerates the installer's local user accounts; the OAST destination provides the publisher with arbitrary out-of-band data capture. This is a textbook dependency-confusion / supply-chain exfiltration beacon.
