The npm package statist-browser-typed-client-mb.product.payments version 20.1.9 includes malicious code that, upon require(), loads a bootstrap script which dynamically constructs hostnames to download a native binary payload from Cloudflare Workers. If HTTPS download fails, it retrieves base64-encoded payload fragments via DNS TXT records from a covert domain. The payload is written to temporary files with misleading names and executed detached from the parent process without signature or hash verification. This package masquerades as a payment client but functions as a native dropper, potentially granting full system compromise.

Systems with this package installed or running are considered fully compromised. The malicious payload can execute arbitrary native code, potentially allowing attackers full control over the affected system. Any secrets or keys stored on the compromised machine should be considered exposed and require immediate rotation. Removing the package alone may not eliminate all malicious components due to the potential for persistent backdoors or additional malware installed by the dropper.

Immediate removal of the statist-browser-typed-client-mb.product.payments package version 20.1.9 is recommended. All secrets and keys stored on the affected system should be rotated from a separate, uncompromised machine. Due to the high likelihood of full system compromise, a full forensic investigation and system rebuild may be necessary to ensure complete remediation. No official patch or fix is available; users should avoid this package and verify the integrity of dependencies before installation.
