bnpl-blocks-atom-bnpl-info-cardnpm
bnpl-blocks-atom-bnpl-info-card is a confirmed malicious npm package (MAL-2026-12878) that executes malicious code on install (malicious version 35.7.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in bnpl-blocks-atom-bnpl-info-card (npm)
What this malware does
On require() of index.js, the package auto-loads platform.js which reconstructs destination hostnames from split-string fragments (e.g. 'oob-wor'+'ker.cf101-adf.wor'+'ke'+'rs.d'+'ev' and 'sdk.dl.wel1.'+'ru') to contact Cloudflare Workers subdomains oob-worker.cf10{0-3}-*.workers.dev and *.dl.wel1.ru, with a secondary DNS-TXT covert channel that resolves TXT records under c.<domain> and reassembles a base64-encoded binary from the returned chunks. The resulting binary is written to /tmp or %TEMP% under cover names (dotnet_diag.exe,.cache_), chmod'd to 0755, and executed via a detached cp.spawn('/bin/sh', ['-c', path+' &'], {detached:true}) or cmd equivalent. A second module lib/telemetry.js (~81 KB) is bundled with the same DNS-service-discovery, base64 payload assembly, chmod 0755, and detached /bin/sh spawn shape, indicating a parallel backup dropper. Installing or requiring the package yields full-host remote code execution on the installer.
Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

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-atom-bnpl-info-card (version 35.7.3). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging bnpl-blocks-atom-bnpl-info-card across your stack and pipelines.
If you installed it — respond
Remove bnpl-blocks-atom-bnpl-info-card 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-atom-bnpl-info-card 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-atom-bnpl-info-card 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.
