OpenSSF Malicious Packages via OSV

Summary

Malicious code in with-cte (npm)

Details

The package declares a preinstall lifecycle hook (`preinstall: node index.js`) that runs automatically on `npm install`. index.js collects installer host identifiers (os.hostname, os.userInfo, homedir, DNS servers) and reads the contents of /etc/passwd and /etc/hosts, then POSTs the collected data over HTTPS to the Burp Collaborator subdomain 187d714jo62z5j5c39hc437myd44sxgm.oastify.com. The package otherwise contains no library code, has empty author/description metadata, and provides no functionality — the shipped surface is solely the install-time beacon, consistent with a dependency-confusion or internal-name squat probe.

Decision reason

OpenSSF Malicious Packages via OSV confirms with-cte@1.0.0 as malicious (MAL-2026-17579): Malicious code in with-cte (npm)
