easyaillmPyPI
Advisory published Updated
easyaillm is a confirmed malicious PyPI package (MAL-2026-5756) that steals credentials and exfiltrates sensitive data (malicious versions 2.0.15, 2.0.16). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in easyaillm (PyPI)
What this malware does
On pip install easyaillm, setup.py runs exec(base64.b64decode(...)) which decodes to code that fetches https://pastebin.com/raw/hEF5HaFc, treats the response body as a second URL, downloads that URL's bytes to pkg_installer.exe, and executes it via os.system('cmd /c pkg_installer.exe'). The attack stages are concealed behind a base64 blob and exec() indirection, while the package metadata advertises an unrelated LLM/Roblox API purpose as cover. The pastebin source is mutable and anonymous, allowing the operator to swap the second-stage URL and ultimately the executed binary at any time. Installing this package on Windows results in arbitrary attacker-controlled code execution on the installer's machine.
During installation, the obfuscsted code attempts to download and start a malicious executable. The published versions contained issues preventing successful downloading, but it was possible to recover the intended executable during the analysis.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for easyaillm (2 malicious versions).
If you installed it — respond
easyaillm 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 easyaillm 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 easyaillm-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
