bnpl-blocks-atom-bnpl-dolyame-buttonnpm
bnpl-blocks-atom-bnpl-dolyame-button is a confirmed malicious npm package (MAL-2026-12871) that steals credentials and exfiltrates sensitive data (malicious version 35.1.8). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in bnpl-blocks-atom-bnpl-dolyame-button (npm)
What this malware does
On require, index.js loads setup.js which selects a platform-specific binary path for linux/darwin/win32, downloads it over HTTPS from hardcoded Cloudflare Workers hostnames (oob-worker.cf103-07.0.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev) with a DNS-TXT chunked fallback via sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru, writes the payload to a disguised temp path, chmods it 0755, and spawns it detached via /bin/sh -c or cmd /c start. Destination hostnames and sensitive API names (child_process, chmodSync) are reconstructed at runtime from arrays of string fragments to defeat string scanners. Opt-out environment variables (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) and a benign 'analytics_state' filename are used as cover. There is no pinning, no signature check, and the destinations are unrelated to the package publisher. Installing or requiring the package causes an attacker-controlled binary to run on the host.

Detection & response playbook
Credential / info stealerFind 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-dolyame-button (version 35.1.8). 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-dolyame-button across your stack and pipelines.
If you installed it — respond
bnpl-blocks-atom-bnpl-dolyame-button is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If bnpl-blocks-atom-bnpl-dolyame-button 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-dolyame-button 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.
