MAL-2026-12882

Summary: Malicious code in bnpl-blocks-atom-bnpl-news-card (npm)

Details: Source: amazon-inspector (dcaf0c737c210018a282e73bbd1570e041a0c70f1043dcdd614e93ac64d8dd68) On require() of this package, _helpers.js selects a platform-specific URL, fetches an opaque binary from obfuscated Cloudflare Workers hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.workers.dev) with DNS-TXT fallback resolution via wel1.ru subdomains (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru), writes the payload to /var/tmp or %TEMP% under disguised names (.cache_, dotnet_diag_), chmods it to 0755, and spawns it detached via /bin/sh -c or cmd. A.analytics_state marker file throttles reruns. Destination hostnames are assembled at runtime from split-string arrays joined together to evade static analysis. The package's advertised purpose is a UI news card, which has no legitimate need to download and execute a native binary at import time. Source: ghsa-malware (8857b4d28c222d8033ac7c69c6a5bc8ba52d8e0ffba5693f07481ce62c769c01) 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.
