Remote access tools with built-in features may interact directly using APIs to gather information. Information may also be acquired through system management tools such as Windows Management Instrumentation and PowerShell.
Monitor for unexpected browser bookmarks viewed in isolation, this showcases part of a chain of behavior that could lead to other activities, such as Collection and Exfiltration, based on the information obtained.
Monitor newly constructed processes, e.g. browsers, for to gather personal information about users (ex: banking sites, interests, social media, etc.)
