llmgeneratorPyPI
Malicious code in llmgenerator (PyPI) Remove it immediately and rotate any exposed credentials.
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
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for llmgenerator (version 2.21). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging llmgenerator across your stack and pipelines.
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 ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks llmgenerator before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

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.
