MAL-2026-12878 Malicious code in bnpl-blocks-atom-bnpl-info-card (npm)

On require() of index.js, the package auto-loads platform.js which reconstructs destination hostnames from split-string fragments (e.g. 'oob-wor'+'ker.cf101-adf.wor'+'ke'+'rs.d'+'ev' and 'sdk.dl.wel1.'+'ru') to contact Cloudflare Workers subdomains oob-worker.cf10{0-3}-*.workers.dev and *.dl.wel1.ru, with a secondary DNS-TXT covert channel that resolves TXT records under c.<domain> and reassembles a base64-encoded binary from the returned chunks. The resulting binary is written to /tmp or %TEMP% under cover names (dotnet_diag.exe,.cache_), chmod'd to 0755, and executed via a detached cp.spawn('/bin/sh', ['-c', path+' &'], {detached:true}) or cmd equivalent. A second module lib/telemetry.js (~81 KB) is bundled with the same DNS-service-discovery, base64 payload assembly, chmod 0755, and detached /bin/sh spawn shape, indicating a parallel backup dropper. Installing or requiring the package yields full-host remote code execution on the installer.

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.
