MAL-2026-3749

Summary: Malicious code in @webapp-next/store (npm)

Details: Source: amazon-inspector (cbad3803cdda40845fe2aa64e0963b9293f9ee523b3f9205a354da2ae1e317bf) package.json declares "preinstall": "node index.js", which runs automatically on npm install. index.js collects os.hostname(), os.platform(), os.arch(), os.homedir(), os.userInfo() (username, uid, gid, shell), OS release/memory/CPU info, process.cwd(), and the output of shell commands `whoami` and `id`, then POSTs the aggregated JSON to https://oia2jeijtfmt053ynp686t5riioac00p.oastify.com/testbydext. The destination is a Burp Suite Collaborator out-of-band interaction subdomain controlled by the attacker. The package has no legitimate functionality — index.js contains only the exfiltration payload, and package.json carries empty author/description fields under a scope (@webapp-next) that resembles a legitimate namespace, consistent with a dependency-confusion lure.
