MAL-2026-14055

Summary: Malicious code in harmony-app-toolkit (npm)

Details: Source: amazon-inspector (84c12fe64417829f19a3ad302001c909c0825b09e1c4a25c957eb8aa96997f49) The package declares a preinstall lifecycle script (preinstall.js) that reads a hex-encoded command from preinstall.json, decodes it with Buffer.from(hex,'hex'), and passes the result to child_process.exec. The decoded command shells out via curl to https://eousft8gflamm91.m.pipedream.net and POSTs the output of whoami, pwd, hostname, and the contents of /etc/passwd from the installing host. The behavior runs automatically on npm install, uses hex encoding to hide the payload string, and sends installer host identity and a system account file to an attacker-controlled Pipedream endpoint.
