Advisory published Updated
bnpl-blocks-independent-bnpl-product-grid is a confirmed malicious npm package (MAL-2026-12967) that executes malicious code on install (malicious version 35.5.5). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in bnpl-blocks-independent-bnpl-product-grid (npm)
What this malware does
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.

Detection & response playbook
Malicious packageFind it
Search your lockfiles and build artifacts for bnpl-blocks-independent-bnpl-product-grid (version 35.5.5).
If you installed it — respond
Remove bnpl-blocks-independent-bnpl-product-grid from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.
Did it already run?
If bnpl-blocks-independent-bnpl-product-grid was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks bnpl-blocks-independent-bnpl-product-grid-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
