🛡️ MAL-2026-4639 — pg-expense-example

Malicious code in pg-expense-example (npm)

Source: amazon-inspector

On require/load, index.js unconditionally collects host identifiers (hostname, username, platform, arch, cwd, pid) and sends them as URL query parameters via HTTPS GET to a hardcoded Burp Collaborator-style domain vwfmeddcdgidvdwpkigkg0l8us5vf3wtx.oast.fun. The package ships no advertised functionality — its only behavior on load is the beacon. package.json has empty author/description fields and declares an unused chalk dependency. A code comment in Azerbaijani (sənin domenin = 'your domain') is consistent with an attacker-controlled callback host, indicating PoC/reconnaissance malware rather than legitimate software.
