MAL-2026-6112

Summary: Malicious code in data-utils-d703 (npm)

Details: Source: amazon-inspector (e172168e5ac500d10ae42718a87676ad44a589b31dbeb5f902ea7fb1c4e6a984) The package declares a postinstall lifecycle hook ("postinstall": "node run.js" in package.json) that executes run.js automatically on install. run.js imports child_process, os, https, and http, calls os.hostname() and os.platform(), and contains multiple POST and GET HTTP request sites. This combination — automatic install-time execution plus host enumeration plus outbound HTTP — is the structural shape of an installer-side exfiltration or dropper, but the specific destinations, payload contents, and execution paths within run.js have not been fully traced, so attacker intent is not confirmed. Manual review of run.js is required to determine whether the network calls target attacker-controlled infrastructure and whether host data is exfiltrated or remote code is fetched and executed. Source: ghsa-malware (fee284139d8880599660922c960afc6566814acb8e76b0e23dab6cca599dd416) 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.
