Summary
Malicious code in search-connector-template (npm)
Details
package.json declares `preinstall: node index.js`, which fires automatically on `npm install`. index.js collects host identity (hostname, username, homedir, DNS servers) and reads installer-owned system files (/etc/passwd, /etc/hosts), then POSTs the JSON payload over HTTPS to a Burp Collaborator OAST subdomain (`615arnt4a5f6ii011q8kggqfk6q1er2g.oastify.com`). This is a classic install-time exfiltration beacon: the destination is attacker-controlled, the data leaving the host belongs to the installer rather than the package author, and execution requires no user action beyond running `npm install`.
Decision reason
OpenSSF Malicious Packages via OSV confirms search-connector-template@1.1.0 as malicious (MAL-2026-4664): Malicious code in search-connector-template (npm)
