Advisory published Updated
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.

Search your lockfiles and build artifacts for dolyame-boxy-atom-bnpl-popup (version 35.9.3).
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 installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks dolyame-boxy-atom-bnpl-popup-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
