## What is MAL-2026-12967?

MAL-2026-12967 is a malicious package in bnpl-blocks-independent-bnpl-product-grid, published on 5 Aug 2026. 

### Official description

The package advertises a BNPL product-grid block, but top-level require('./_platform') from index.js triggers _platform.js, which on load selects a platform-specific endpoint, downloads an opaque binary over HTTPS from Cloudflare Workers hosts, writes it to /var/tmp or %TEMP% under disguise filenames (.cache_*, dotnet_diag_*.exe), chmods it 0o755, and spawns it detached via /bin/sh or cmd. Destination hostnames are reconstructed at runtime by concatenating string fragments (e.g. ['oob-w','orker.cf100-416.work','ers.de','v'].join(''); ['sdk.dl.wel1.','ru'].join('')) to evade static analysis. If the HTTPS fetch fails, the module falls back to a DNS TXT channel: it resolves c.<domain> for a chunk count, batches TXT lookups against N.<domain> under *.dl.wel1.ru, base64-decodes the concatenated response into a Buffer, and executes those bytes through the same activation path. No hash or signature verification is performed, the delivery infrastructure is unrelated to the advertised BNPL purpose, and DO_NOT_TRACK / DISABLE_TELEMETRY env gates serve as cover.

## What should I do about MAL-2026-12967?
