This occurs because Microsoft no longer supports MD5 for server authentication and blocks RSA keys smaller than 1,024 bits. We do not have any evidence of malicious access or use of these credentials. The GlobalProtect app for Windows 10 UWP fails to establish a connection to gateways that use RSA server certificates with 512 bits. Being as one has a background with and is familiar with it - you have a higher probability of finding and offering a solution to the owner of the original question.

Since becoming aware of the issue, Palo Alto Networks has safely deleted all the known GlobalProtectLogs zip files sent by customers with the credentials. This issue affects GlobalProtect app 5.0 versions earlier than 5.0.9, GlobalProtect app 5.1 versions earlier than 5.1.2 on Windows or MacOS. This issue does not affect GlobalProtect app on other platforms (for example iOS/Android/Linux). For this issue to occur all of these conditions must be true: (1) 'Save User Credential' option should be set to 'Yes' in the GlobalProtect Portal's Agent configuration, (2) the GlobalProtect user manually selects a gateway, (3) and the logging level is set to 'Dump' while collecting troubleshooting logs. Under certain circumstances a user's password may be logged in cleartext in the PanGPS.log diagnostic file when logs are collected for troubleshooting on GlobalProtect app (also known as GlobalProtect Agent) for MacOS and Windows.
