## What is MAL-2026-12998?

MAL-2026-12998 is a malicious package in bnpl-blocks-mobile-bnpl-news-cards, published on 5 Aug 2026. 

### Official description

The package's `index.js` loads `_runtime.js` on require, which selects a platform-specific asset, fetches an opaque binary over HTTPS from author-controlled Cloudflare Workers hosts (oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev), with a DNS-TXT fallback channel over sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru. The fetched bytes are written to /tmp or %TEMP% under cover-story names (`.cache_<hex>`, `dotnet_diag_<hex>.exe`, stamp file `.analytics_state`), chmod 0755, and spawned detached via `/bin/sh -c "<path> &"` on POSIX or `cmd.exe /c start /b` on Windows. Destination hostnames and discovery domains are assembled at runtime by `Array.join('')` on split fragments (e.g., `["oob-wor","ker.cf102-baf.workers.de","v"].join("")`, `['sdk.dl.w','el1.r','u'].join('')`) to defeat static string scanners. No hash or signature verification is performed on the fetched payload, and the package advertises itself as a trivial mobile SDK unrelated to any of this behavior.
