Quick takeaways
Identifying unsecured credentials in common places like file shares and logon scripts is vital for enhancing security during assessments.
Lesser-known vulnerabilities, such as credential leaks in app logs and email notes, pose significant risks that need proactive management to prevent breaches.
Deep dives
The Importance of Credential Discovery
Finding user credentials is a critical aspect of lateral movement within environments. Attackers often leverage unsecured credentials found in various locations to gain access to systems. Some common areas where credentials can be found include unattended installation files, which may contain Base64-encoded credentials for local administrator accounts. IT administrators and penetration testers should be aware of these potential vulnerabilities during their security assessments and remediation efforts.
Common Locations for Securing Credentials
File shares are a prevalent source for discovering unsecured credentials, making them a primary focus during assessments. Penetration testers often refer to themselves as 'file share archaeologists' as they sift through folders to locate sensitive information. Additionally, the Windows registry may harbor credentials, particularly from remote access software installations, which can be either encrypted or plaintext. Awareness of these areas enables IT professionals to implement better practices to secure sensitive data.
Utilizing Logon Scripts and Group Policies
Logon scripts represent another common vulnerability where credentials can be exposed, as they are often created to facilitate network share access for different users. These scripts may include plaintext usernames and passwords, easily accessible by anyone with user permissions. Group Policy settings can also inadvertently expose sensitive information if credentials are stored without proper security measures. Regularly reviewing these practices can significantly enhance the security posture of a network environment.
Lesser-Known Sources of Credentials
Beyond the commonly known locations, there are numerous lesser-known sources where unsecured credentials lurk. For instance, applications can leak sensitive information in their log files, config files, and even through crash dumps. Another surprising avenue is the notes section in email contacts, which some users might utilize for storing passwords. Identifying and securing these hidden credentials can prove crucial in safeguarding organizational integrity against potential breaches.
In this very special Halloween episode, prepared to be scared. Brad and Spencer discuss the common and not so common locations that we find credentials during penetration tests. This includes plaintext credentials and other types of credential material like API keys.
