aws-enumerateiamPyPI
Advisory published Updated
aws-enumerateiam is a confirmed malicious PyPI package (MAL-2025-191686) that steals credentials and exfiltrates sensitive data (malicious versions 1.0.0, 1.0.1, 1.0.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in aws-enumerateiam (PyPI)
What this malware does
Before creating the boto3 client, package exfiltrates user's credentials. In this version, the exfiltrating is masked as connecting to an AWS component. The URL to the component is expected to be hex-encoded. In fact, the related GitHub project uses it as a dependency and sets as the URL the attacker-controlled domain. In this way, the AWS libraries are abused to generate the request to the malicious infrastructure and exfiltrate credentials.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for aws-enumerateiam (3 malicious versions).
If you installed it — respond
aws-enumerateiam 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 aws-enumerateiam 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 aws-enumerateiam-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
