MAL-2026-13296 Malicious code in dolyame-boxy-atom-desktop-bnpl-text (npm)

The package's index.js silently loads loader.js via a swallowed try/catch (try { require('./_loader'); } catch (_) {}). loader.js assembles one of three Cloudflare Workers hostnames via array-join string-splitting (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev) and a DNS-TXT fallback under *.dl.wel1.ru, downloads a platform-specific binary, writes it to /tmp or %TEMP% under a disguised name (.cache<rnd> on Unix, dotnet_diag<rnd>.exe on Windows), chmods it 0755, and spawns it detached via /bin/sh -c or cmd. The exported class is a no-op shell; the package ships no functionality matching its advertised BNPL/React-component identity. Destination hostnames and the DNS-TXT covert channel (numbered TXT chunk reassembly of base64 payload) are obfuscated to evade static detection.

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.
