What is MAL-2026-5764?
MAL-2026-5764 is a malicious package in sys-info-cli-app, published on 14 Jun 2026.
Official description
The package's collect.js gathers host identifiers (os.hostname(), os.homedir()) along with filesystem and child_process introspection and POSTs them to a hardcoded external endpoint at http://aab.sportsontheweb.net. The destination is unrelated to any legitimate npm distribution infrastructure and the data flow has no documented purpose tied to the package's stated function. The combination of os/child_process/fs reads with an outbound POST to an attacker-controlled domain is the canonical host-reconnaissance / exfiltration shape. Installing or loading this package causes installer host metadata to be sent off-host to a third-party server.
What should I do about MAL-2026-5764?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
