MAL-2026-15592 Malicious code in fuels-core (npm)

The package's bin script (bin/cli.js) collects whoami, os.hostname(), and os.platform() and POSTs them along with the package name to a hardcoded Cloudflare Workers URL (https://oobme.kunalsharma0553.workers.dev/r/7bq6fz3l15r9) with no configuration or opt-out. The bin is exposed as generate-schema-viem, and the package name fuels-core resembles the Fuel ecosystem's fuels package, consistent with typosquat/dependency-confusion reconnaissance targeting installers who resolve or invoke this package (e.g., via npx). The package.json description openly states its purpose is to POST package name and whoami to an OOB callback.

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.

The OpenSSF Package Analysis project identified 'fuels-core' @ 1.0.0 (npm) as malicious.

It is considered malicious because:

• The package communicates with a domain associated with malicious activity.

• The package executes one or more commands associated with malicious behavior.
