What this malware does

On import, kotoraka decodes base64-obfuscated filesystem paths pointing at the user's Monero wallet directory (Windows: C:\Users<user>\Documents\Monero; Linux: /home/<user>/Monero), terminates any running feather or monero processes to release file locks, archives the wallet directory into a zip, and uploads it to the Telegram Bot API (api.telegram.org sendDocument) using a hardcoded bot token and chat_id (-5357046713). The Telegram bot token and target paths are stored as base64 literals decoded at runtime. The declared purpose of the package (an HTTP speed-up library) is unrelated to the actual behavior. The exfiltration fires as a top-level side effect of import kotoraka, with no user interaction.

During import, the package exfiltrates cryptocurrency wallet files.

Detection & response playbook

Credential / info stealer
  1. Find it

    Search your lockfiles and build artifacts for kotoraka (version 0.1.0).

  2. If you installed it — respond

    kotoraka 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.

  3. Did it already run?

    If kotoraka 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.

Frequently asked questions

No. kotoraka on PyPI has been identified as a malicious package (version 0.1.0 flagged). It should be removed immediately — do not install or keep it in your dependency tree.

Detect & block this

O3 blocks kotoraka-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
