MAL-2026-15598 Malicious code in verify-contract-ethers (npm)

The package ships a single bin entry (bin/cli.js) that, when invoked, runs whoami and POSTs the package name, username, hostname, and platform to a hardcoded Cloudflare Workers callback at https://oobme.kunalsharma0553.workers.dev/r/7bq6fz3l15r9. The bin is registered under the name fuels-typegen while the package itself is published as verify-contract-ethers, a name/bin mismatch consistent with typosquatting or dependency-confusion against fuels-typegen / verify-contract. The package's declared description openly states its purpose is to POST package name and whoami to an out-of-band callback, and no legitimate functionality is present beyond that beacon.

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 'verify-contract-ethers' @ 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.
