MAL-2026-4590

Summary: Malicious code in json-to-simple-graphql-schema (npm)

Details: Source: amazon-inspector (b9998f4fd6abaaefcf6bd610ce0b558f0e1eb22c9d4dae07a111c27cc7f7322c) The package contains a poc.js script that collects host reconnaissance data (os.hostname(), os.platform(), output of `whoami` via child_process) and POSTs it to a remote endpoint over https.request. The combination of os/system enumeration, child_process command execution (e.g. `whoami`), and an outbound HTTPS POST in the same file is the canonical host-reconnaissance and exfiltration shape. The package name suggests a JSON-to-GraphQL schema converter, and there is no legitimate reason for such a converter to ship a script that runs `whoami`, reads host identity, and ships the results off-host. Installing or executing this package gives the publisher tangible host reconnaissance data from the installer's machine. Source: ghsa-malware (aac4fc25ca9c9d5b64e66c565f14cd4f07873a2e716834ba633239df20a99bab) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
