MAL-2026-15594 Malicious code in generate-schema-ethers (npm)

On require()/npx invocation, bin/cli.js runs whoami and POSTs the OS username, hostname, platform, and package name as JSON to the hardcoded URL https://oobme.kunalsharma0553.workers.dev/r/7bq6fz3l15r9. The exfiltration fires unconditionally with no advertised feature justifying the network call, no user consent, and no configurability. The package name resembles legitimate schema-generation tooling, consistent with a typosquat/dependency-confusion reconnaissance 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 'generate-schema-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.
