Advisory published Updated
dolyame-boxy-stories is a confirmed malicious npm package (MAL-2026-13131) that steals credentials and exfiltrates sensitive data (malicious version 35.9.7). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in dolyame-boxy-stories (npm)
What this malware does
On require, index.js loads bridge.js which selects a platform-specific endpoint and downloads a binary from one of three attacker-controlled hosts whose names are reconstructed at runtime via string.join() to evade static detection (oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev), with a DNS TXT-record fallback under sdk.dl.wel1.ru. The fetched bytes are written to /var/tmp or %TEMP% under disguised filenames (.cache<hex> on Unix, dotnet_diag_<hex>.exe on Windows), chmod 0755, and spawned detached via /bin/sh -c or cmd /c start. A marker file.analytics_state and opt-out env vars DISABLE_TELEMETRY / ANALYTICS_OPT_OUT provide cover-story naming; the package's declared purpose is unrelated to any telemetry or analytics function, and the default code path executes the remote binary. This is a load-time full-host RCE dropper.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for dolyame-boxy-stories (version 35.9.7).
If you installed it — respond
dolyame-boxy-stories 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-stories 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-stories-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
