Warning: PDQ Deploy Users at Risk of Credential Theft

Admin Credential Theft Risk Exposed in PDQ Deploy: What Users Need to Know

The CERT Coordination Center (CERT/CC) has issued a crucial vulnerability note highlighting the risk of admin credential theft for users of PDQ Deploy. This widely used service enables system administrators to efficiently deploy software and updates across their network. However, a recent discovery reveals that admin credentials, created during the software installation process, can be exploited by attackers with local access—posing a significant security threat.

Understanding the Vulnerability in PDQ Deploy

According to the CERT/CC notice published on Wednesday, the vulnerability arises when administrators utilize PDQ Deploy’s “Deploy User” run mode. This mode temporarily generates credentials on the target device to facilitate software installations. Even though these credentials are deleted post-installation, they remain retrievable from active memory until the deletion occurs. Attackers can harness tools like Mimikatz to extract these credentials, thereby compromising the security of the network.

Key Points About the Vulnerability:

Deploy User Run Mode Risk: Admin credentials can be stolen before deletion.
Local System Mode Vulnerability: This mode, which operates with lower privileges, still utilizes the “Deploy User” account, making it susceptible to credential theft.
Potential for Lateral Movement: Static credentials created via domain accounts can be exploited across other devices connected through Active Directory.

Recommendations for PDQ Deploy Users

In response to the vulnerability, PDQ Deploy has advised users to adopt several best practices to enhance security:

Utilize Windows Local Administrator Password Solution (LAPS): This tool can help create unique credentials for each endpoint when deploying software.
Implement Least Privilege Principle: Ensure that credentials used on target machines only have the minimum necessary permissions to execute required commands.
Avoid Domain Admin Credentials: Only use these credentials when automating actions on a domain controller. For all other deployments, opt for lower-permission credentials.

Alternative Deployment Options

CERT/CC suggests that users consider the “Logged on User” deploy mode, which utilizes the active credentials of the currently logged-in user, thus enhancing security. However, it’s important to note that this feature is available only in the Enterprise version of PDQ Deploy and requires user interaction during installations.

Historical Context: PDQ Deploy Exploits

The risks associated with PDQ Deploy are not new. In April 2024, an organization was compromised when an attacker leveraged PDQ Deploy to propagate Medusa ransomware. Similarly, in 2022, InfoGuard reported that PDQ Deploy was exploited for ransomware deployment on targeted machines.

Conclusion and Call to Action

In light of these findings, it is vital for PDQ Deploy users to remain vigilant and implement the recommended security measures. By doing so, they can significantly reduce the risk of credential theft and enhance their network’s security posture.
