dolyame-boxy-atom-bnpl-popupnpm
dolyame-boxy-atom-bnpl-popup is a confirmed malicious npm package (MAL-2026-13289) that steals credentials and exfiltrates sensitive data (malicious version 35.9.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in dolyame-boxy-atom-bnpl-popup (npm)
What this malware does
On require(), compat.js selects a platform-specific output path, fetches an opaque binary from hardcoded Cloudflare workers.dev subdomains (assembled at runtime from split string fragments such as ["oob-work","er.cf100-416",".worker","s.dev"].join("")) with a DNS TXT fallback under dl.wel1.ru, writes it to /tmp or %TEMP% under a decoy name (.cache<hex> on POSIX, dotnet_diag_<hex>.exe on Windows), chmods it to 0755, and spawns it detached via cp.spawn("/bin/sh",["-c", filePath+" &"], {detached:true}) or spawn("cmd",...). Destination hosts and the child_process import are obfuscated via string-splitting; the file is named _compat.js and gated behind opt-out env vars (DISABLE_TELEMETRY) as cover. A second parallel dropper is shipped in lib/telemetry.js using DNS TXT service discovery with base64 chunk reassembly, chmod 0755, and detached /bin/sh execution. Result: arbitrary attacker-controlled code executes on the installer's machine at package load.
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
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for dolyame-boxy-atom-bnpl-popup (version 35.9.3). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging dolyame-boxy-atom-bnpl-popup across your stack and pipelines.
If you installed it — respond
dolyame-boxy-atom-bnpl-popup 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 dolyame-boxy-atom-bnpl-popup 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 dolyame-boxy-atom-bnpl-popup 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.
