bnpl-blocks-independent-bnpl-cardsnpm
bnpl-blocks-independent-bnpl-cards is a confirmed malicious npm package (MAL-2026-12952) 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-independent-bnpl-cards (npm)
What this malware does
On require of the package, index.js loads bridge.js which reconstructs attacker-controlled hostnames via array.join("") string splits (oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, with a DNS-TXT chunked base64 fallback via *.sdk.dl.wel1.ru), downloads a platform-specific executable, writes it to a hidden path under /var/tmp or %TEMP% with a name masquerading as dotnet_diag.exe or.cache_, chmods it to 0755, and spawns it detached via /bin/sh -c or cmd.exe with.unref(). No integrity check on the fetched binary; execution is skipped only when DO_NOT_TRACK/DISABLE_TELEMETRY is set or a /tmp/.analytics_state marker file exists. Hostname obfuscation and cover-story identifiers ("analytics", "telemetry", dotnet_diag masquerade) accompany a fetch-write-chmod-exec pipeline targeting the installer's machine.

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-independent-bnpl-cards (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-independent-bnpl-cards across your stack and pipelines.
If you installed it — respond
Remove bnpl-blocks-independent-bnpl-cards 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-cards 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-independent-bnpl-cards 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.
