T1070.007 Clear Network Connection History and Configurations

Sub-technique of: T1070

High-Level Description

Adversaries may clear or remove evidence of malicious network connections in order to clean up traces of their operations. Configuration settings as well as various artifacts that highlight connection history may be created on a system and/or in application logs from behaviors that require network connections, such as Remote Services or External Remote Services. Defenders may use these artifacts to monitor or otherwise analyze network connections created by adversaries.

Network connection history may be stored in various locations. For example, RDP connection history may be stored in Windows Registry values under :

• HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Default
• HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Servers

Windows may also store information about recent RDP connections in files such as C:\Users\%username%\Documents\Default.rdp and C:\Users\%username%\AppData\Local\Microsoft\Terminal Server Client\Cache\. Similarly, macOS and Linux hosts may store information highlighting connection history in system logs (such as those stored in /Library/Logs and/or /var/log/).

Malicious network connections may also require changes to third-party applications or network configuration settings, such as Disable or Modify System Firewall or tampering to enable Proxy. Adversaries may delete or modify this data to conceal indicators and/or impede defensive analysis.
