## What is MAL-2026-12969?

MAL-2026-12969 is a malicious package in bnpl-blocks-independent-bnpl-separator, published on 5 Aug 2026. 

### Official description

Requiring this package triggers _init.js, which selects a platform-specific payload URL from string-concat-obfuscated Cloudflare Workers hostnames (oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev) with a DNS-TXT base64 reassembly fallback to sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru. The fetched bytes are written to /tmp or the Windows temp directory under disguised names such as dotnet_diag_*.exe and.cache_*, chmod 0755, and spawned detached via /bin/sh -c or cmd.exe /c start /b. Cover-story naming (`.analytics_state` run-once marker, DISABLE_TELEMETRY/DO_NOT_TRACK env checks) frames the behavior as analytics. A secondary dropper with the same fetch/writeFile/chmod/spawn shape ships in lib/telemetry.js, using base64-decoded payload chunks and split-string require('child_'+'process'). The destinations are non-publisher infrastructure, the payload bytes are opaque, and hostnames plus module names are assembled at runtime to evade static review.

## What should I do about MAL-2026-12969?
