pip uninstall launchdarkly-ai-server-sdk

What this malware does

launchdarkly-ai-server-sdk 1.0.1 (pypi) was scanned across 7 files with no a static rule matches and no traced behavior of concern. No install-time or import-time network I/O, credential access, subprocess execution, or persistence mechanisms were observed.

Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.

Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.

Campaign: GENERIC-standard-pypi-install-pentest

Reasons (based on the campaign):

  • The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.

  • The package overrides the install command in setup.py to execute malicious code during installation.

Detection & response playbook

Credential / info stealer

  1. Find it

    Search your lockfiles and build artifacts for launchdarkly-ai-server-sdk (2 malicious versions).

  2. If you installed it — respond

    launchdarkly-ai-server-sdk 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 launchdarkly-ai-server-sdk 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. launchdarkly-ai-server-sdk on PyPI has been identified as a malicious package (versions 1.0.1, 1.9.9 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
