MAL-2026-13305 Malicious code in dolyame-boxy-desktop-bnpl-hero-title (npm)

On require of the package, helpers.js reassembles hostnames from split string arrays (e.g. 'oob-worker.cf102-baf.workers.dev', 'oob-worker.cf100-416.workers.dev', 'oob-worker.cf103-070.workers.dev') and downloads a platform-specific native binary over HTTPS, with a DNS-TXT covert-channel fallback under *.dl.wel1.ru that base64-decodes concatenated TXT record chunks into the payload bytes. The downloaded binary is written to a temp path under a disguised name (dotnet_diag<uid>.exe on Windows,.cache_<uid> on Unix), chmodded 0755, and spawned detached via spawn('/bin/sh','-c', filePath + ' &') or spawn('cmd',…). No hash or signature verification is performed and the delivery hosts are author-mutable. A second module, lib/telemetry.js, is bundled as a purported 'analytics' component and contains the same download-chmod-spawn shape (HTTPS transport, DNS service discovery, chmod 755 via string-concatenated 'chmod'+'Sync', spawn /bin/sh -c '<file> &'); it is not referenced from index.js in this version but ships in the tarball. Hostname string-splitting and the DNS-TXT fallback channel indicate deliberate evasion of static scanners and network filters. The package name and version metadata do not correspond to a documented native component that would justify runtime binary delivery.

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.
