bnpl-blocks-mobile-bnpl-reviewsnpm
bnpl-blocks-mobile-bnpl-reviews is a confirmed malicious npm package (MAL-2026-13003) that executes malicious code on install (malicious version 35.5.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in bnpl-blocks-mobile-bnpl-reviews (npm)
What this malware does
On require() of the package, index.js loads bootstrap.js which selects a platform-specific URL, downloads an executable from obfuscated Cloudflare Workers mirrors (hostnames assembled at runtime via string-splitting to oob-worker.cf*.workers.dev), writes it to /var/tmp or %TEMP% under a disguised filename such as dotnet_diag<hex>.exe or.cache_<hex>, chmods 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start. A DNS-TXT covert channel under c.*.dl.wel1.ru reconstructs a base64 payload as fallback delivery. Execution is gated once per host via a /tmp/.analytics_state stamp. The delivery infrastructure is not the package publisher's, the fetched bytes are unsigned and unverified, the destination path and filename are disguised, and execution is detached — the shape is a supply-chain dropper, not a legitimate runtime install.

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-reviews (version 35.5.3). 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-reviews across your stack and pipelines.
If you installed it — respond
Remove bnpl-blocks-mobile-bnpl-reviews 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-reviews 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-reviews 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.
