MAL-2026-13326 Malicious code in dolyame-boxy-independent-bnpl-preset-container (npm)

index.js require()s platform.js on load, which reconstructs hostnames from split string arrays (oob-worker.cf10*-*.workers.dev and sdk.dl.wel1.ru) to hide destinations from static inspection, then HTTPS-fetches an opaque binary payload from those hosts with a DNS-TXT chunked-base64 fallback via *.dl.wel1.ru. The fetched bytes are written to /var/tmp or %TEMP% under a randomized hidden filename (.cache<rand> / dotnet_diag_<rand>.exe), chmod 0755, then spawned detached via /bin/sh -c or cmd.exe (_platform.js line 119-125). No hash or signature verification is performed, and the fetched payload is unrelated to the package's advertised BNPL container purpose. A.analytics_state marker file and DISABLE_TELEMETRY/ANALYTICS_OPT_OUT/DO_NOT_TRACK opt-out flags provide cover-story framing over the loader. The dropper fires at module require time.

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.
