Advisory published Updated
dolyame-boxy-atom-bnpl-dangerously-html is a confirmed malicious npm package (MAL-2026-13285) that steals credentials and exfiltrates sensitive data (malicious version 35.5.4). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in dolyame-boxy-atom-bnpl-dangerously-html (npm)
What this malware does
On require of the package, index.js loads loader.js which reconstructs attacker-controlled hostnames via string-split.join('') to evade scanners (mirrors of the form oob-worker.cf10{0,1,2}-{baf,adf}.workers.dev and DNS TXT fallback domains under wel1.ru such as sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru), selects a platform/arch-specific asset, downloads a binary from one of the anonymous Cloudflare Workers hosts (with a DNS-over-TXT fallback that base64-reassembles bytes from <n>.<domain> TXT records), writes it to /var/tmp/.cache<rand> on Unix or %TEMP%\dotnet_diag_<rand>.exe on Windows, chmod 0755, and spawns it detached via /bin/sh -c or cmd.exe. A marker file named.analytics_state and comments referring to 'opt-out environment variables' present a telemetry cover story. There is no hash or signature verification on the downloaded bytes, the destinations are anonymous hosts unrelated to any legitimate publisher, and the package name itself is a lookalike combining unrelated brand/technology tokens.
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
Search your lockfiles and build artifacts for dolyame-boxy-atom-bnpl-dangerously-html (version 35.5.4).
If you installed it — respond
dolyame-boxy-atom-bnpl-dangerously-html 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-dangerously-html 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-dangerously-html-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
