What this malware does

When calling the Email function, the code creates a backdoor script and attempts to achieve persistence. The script connects to a Telegram bot and awaits commands to execute.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Detection & response playbook

Credential / info stealer
  1. Find it

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

  2. If you installed it — respond

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