## What is MAL-2026-13006?

MAL-2026-13006 is a malicious package in bnpl-blocks-mobile-bnpl-shopping-header, published on 5 Aug 2026. 

### Official description

On require() of the package, index.js loads _init.js which selects a platform-specific endpoint, downloads an opaque binary from rotating Cloudflare Workers mirror hosts (oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev) with a DNS-TXT fallback via *.dl.wel1.ru, writes it to /var/tmp or %TEMP% under a disguised name (dotnet_diag_*.exe,.cache_*), chmods 755, and spawns it detached via /bin/sh -c or cmd.exe /c start /b. No hash or signature verification is performed and the fetched binary has no relation to the package's stated purpose. Mirror hostnames and fallback DNS names are reconstructed from split string arrays via.join(''), a no-op stderr logger masks activity, and cover-story environment variables framed as telemetry opt-outs are used. lib/telemetry.js (81KB) contains a parallel dropper implementation with the same fetch → write → chmod 755 → spawn '/bin/sh -c filePath &' pattern, base64 chunk assembly, and child_process obtained via string concatenation (require("child_" + "process")).
