# MAL-2026-12968: Malicious code in bnpl-blocks-independent-bnpl-scheme (npm)


- **Type:** Malicious package
- **Package:** `bnpl-blocks-independent-bnpl-scheme` (npm)
- **Published:** 5 Aug 2026

## What is MAL-2026-12968?

MAL-2026-12968 is a malicious package in bnpl-blocks-independent-bnpl-scheme, published on 5 Aug 2026. 

### Official description

The package ships a loader (_loader.js) that assembles remote hostnames at runtime from string-split arrays (reconstructing subdomains of wel1.ru and a cloudflare workers.dev host) to evade static detection, issues an https.get to those endpoints, writes the response to disk, chmods it executable (0755), and spawns it via /bin/sh -c or cmd. A sibling module lib/telemetry.js (~81KB) presents itself as an 'analytics SDK' but contains the same dropper primitives (base64 chunk decode, chmodSync 0755, cp.spawn('/bin/sh',['-c', filePath+' &'])). Hostname reconstruction via array split/join combined with a fetch-write-chmod-exec chain is an obfuscated remote code delivery mechanism, not legitimate SDK behavior. The runtime-assembled destinations do not match any documented publisher endpoint, and the code path is reachable on load. Installing or loading this package results in execution of attacker-controlled code fetched from wel1.ru subdomains and a *.workers.dev host on the installer's machine.

## What should I do about MAL-2026-12968?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
