ezllmgenPyPI
Advisory published Updated
ezllmgen is a confirmed malicious PyPI package (MAL-2026-5769) 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 ezllmgen (PyPI)
What this malware does
setup.py downloads the first line of https://pastebin.com/raw/yBcUM1QB via urllib and passes it directly to os.system(f'cmd /c "{cmd_pastebin}"') during package installation. The Pastebin source is anonymous and author-mutable, so any installer running pip install EzLLMGen unconditionally executes whatever shell command is currently posted there, with no pinning, hash check, or signature. The package ships no Python modules — the src tree contains only an egg-info directory and the PKG-INFO metadata is placeholder text (Name/Author/Summary all set to 'EzLLMGen'), so there is no legitimate functionality to balance against the dropper. The install-time fetch-and-execute is the package's sole purpose.
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 ezllmgen (version 2.21).
If you installed it — respond
ezllmgen 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 ezllmgen 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 ezllmgen-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
