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. Shell History), operating system or application-specific repositories (e.g. Credentials in Registry), or other specialized files/artifacts (e.g. Private Keys).
Platforms: Windows, SaaS, IaaS, Linux, macOS, Containers, Network Devices, Office Suite, Identity Provider
The following tests are from Atomic Red Team and provide actionable ways to test this technique:
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/
Supported Platforms: linux, macos, iaas:aws
export AWS_REGION=#{aws_region}
cd #{stratus_path}
echo
./stratus warmup aws.credential-access.ec2-get-password-data
./stratus detonate aws.credential-access.ec2-get-password-data --force
Dependencies:
Find passwords in the powershell history files Searching for following strings: "password", "-p", "key", "pwd", "pass"
Supported Platforms: windows Elevation Required: Yes
ls -R C:\Users\*\AppData\Roaming\Microsoft\Windows\PowerShell\PSReadLine\ConsoleHost_history.txt | Select-String "password", "-p", "key", "pwd", "pass"
If Atomic Red Team tests are not applicable, manually verify the technique by:
Identify Attack Surface: Determine if the target environment is susceptible to Unsecured Credentials by examining the target platforms (Windows, SaaS, IaaS).
Assess Existing Defenses: Review whether mitigations for T1552 are in place. If defenses are absent or misconfigured, this technique may be exploitable.
Execute Test: Use tools and methods described in the MITRE ATT&CK page and external references below.
When possible, store keys on separate cryptographic hardware instead of on the local system.
Apply patch KB2962486 which prevents credentials from being stored in GPPs.
Ensure that developers and system administrators are aware of the risk associated with having plaintext passwords in software configuration files that may be left on endpoint systems or servers.
Remove vulnerable Group Policy Preferences.
Use strong passphrases for private keys to make cracking difficult. Do not store credentials within the Registry. Establish an organizational policy that prohibits password storage in files.
There are multiple methods of preventing a user's command history from being flushed to their .bash_history file, including use of the following commands:
set +o history and set -o history to start logging again;
unset HISTFILE being added to a user's .bash_rc file; and
ln -s /dev/null ~/.bash_history to write commands to /dev/nullinstead.
Limit access to the Instance Metadata API. A properly configured Web Application Firewall (WAF) may help prevent external adversaries from exploiting Server-side Request Forgery (SSRF) attacks that allow access to the Cloud Instance Metadata API.
Restrict file shares to specific directories with access only to necessary users.
Limit network access to sensitive services, such as the Instance Metadata API.
Preemptively search for files containing passwords or other credentials and take actions to reduce the exposure risk when found.
If it is necessary that software must store credentials in the Registry, then ensure the associated accounts have limited permissions so they cannot be abused if obtained by an adversary.
