bnpl-blocks-desktop-bnpl-category-gallerynpm
bnpl-blocks-desktop-bnpl-category-gallery is a confirmed malicious npm package (MAL-2026-12918) that typosquats a legitimate package to trick installs (malicious version 35.2.8). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in bnpl-blocks-desktop-bnpl-category-gallery (npm)
What this malware does
The package's main entry unconditionally requires support.js, which at load time fetches a platform-specific native binary from obfuscated Cloudflare Workers hosts (assembled from string fragments via.join(""), e.g. oob-worker.cf99-9b3.workers.dev and oob-worker.cf101-adf.workers.dev), writes it to /var/tmp/.cache<hex> on Unix or %TEMP%\dotnet_diag_<hex>.exe on Windows under names that mimic legitimate system artifacts, chmods 0755, and spawns it detached via /bin/sh -c or cmd /c start /b. If the HTTPS fetch fails, _support.js reconstructs a base64-encoded payload from chunked DNS TXT records at sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru and executes the assembled binary. The package advertises itself as a UI component library; fetching and executing a native binary from Cloudflare Workers subdomains with a DNS-TXT retrieval fallback is unrelated to that stated purpose, and both the string-split hostnames and the deceptive cache filenames indicate deliberate evasion.

Detection & response playbook
TyposquatFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for bnpl-blocks-desktop-bnpl-category-gallery (version 35.2.8). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging bnpl-blocks-desktop-bnpl-category-gallery across your stack and pipelines.
If you installed it — respond
bnpl-blocks-desktop-bnpl-category-gallery is a typosquat — you almost certainly intended a legitimately-named package. Remove bnpl-blocks-desktop-bnpl-category-gallery, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If bnpl-blocks-desktop-bnpl-category-gallery was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks bnpl-blocks-desktop-bnpl-category-gallery before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.
