bnpl-blocks-mobile-bnpl-category-gallerynpm
bnpl-blocks-mobile-bnpl-category-gallery is a confirmed malicious npm package (MAL-2026-12984) that executes malicious code on install (malicious version 35.6.5). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in bnpl-blocks-mobile-bnpl-category-gallery (npm)
What this malware does
On any require() of this package, index.js loads loader.js, which reconstructs destination hostnames at runtime from array-join fragments (oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, with DNS-TXT fallbacks under *.dl.wel1.ru), downloads a platform-specific binary from those hosts, writes it to /tmp or %TEMP% under masquerading filenames such as dotnet_diag.exe or.cache_, chmods it 0755, and spawns it detached via cp.spawn("/bin/sh", ["-c", fp+" &"], {detached:true}) or spawn("cmd",...). A second, parallel dropper is bundled in lib/telemetry.js: a base64-decoded payload buffer is written, chmod'd 0755, and executed via detached /bin/sh. child_process and hostname strings are assembled with require("child_"+"process") and [...].join("") to evade static analysis. The opaque remote payload has no hash or signature verification and originates from non-publisher Cloudflare Workers infrastructure.

Detection & response playbook
Malicious packageFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for bnpl-blocks-mobile-bnpl-category-gallery (version 35.6.5). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging bnpl-blocks-mobile-bnpl-category-gallery across your stack and pipelines.
If you installed it — respond
Remove bnpl-blocks-mobile-bnpl-category-gallery 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-mobile-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-mobile-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.
