Pacu is an open source AWS exploitation framework, designed for offensive security testing against cloud environments. Created and maintained by Rhino Security Labs, Pacu allows penetration testers to exploit configuration flaws within an AWS account, using modules to easily expand its functionality. Current modules enable a range of attacks, including user privilege escalation, backdooring of IAM users, attacking vulnerable Lambda functions, and much more. Pacu is a fairly lightweight program, as it requires only Python3.5+ and pip3 to install a handful of Python libraries. Running install.sh will check your Python version and ensure all Python packages are up to date.
