llmgeneratorPyPI
Advisory published Updated
llmgenerator is a confirmed malicious PyPI package (MAL-2026-5770) that steals credentials and exfiltrates sensitive data (malicious version 2.21). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in llmgenerator (PyPI)
What this malware does
On pip install, setup.py performs an HTTP GET to https://pastebin.com/raw/yBcUM1QB, takes the first line of the response body, and passes it to os.system(f'cmd /c "{cmd_pastebin}"'). The fetched content is mutable, anonymous, and unauthenticated — the author can change what runs on every installer's machine at any time without republishing the package. The package ships no functional Python code (src/ contains only an empty.egg-info directory), confirming the package exists solely as a vehicle for the install-time dropper. The package name impersonates an LLM-tooling brand to attract installs. Installing this package grants arbitrary shell execution on the installer's Windows machine.
During installation, the code attempts to download and start a malicious executable.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for llmgenerator (version 2.21).
If you installed it — respond
llmgenerator 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 llmgenerator 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 llmgenerator-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
