How does detecting this stealth remote assistance attack work, and what limitations exist?

Detection focuses on monitoring for registry changes to `fAllowToGetHelp`, enabling of the 'Remote Assistance' firewall rule, and the creation/execution of `.msrcIncident` invitation files. However, the article notes that administrator privileges are already assumed, meaning the system is likely compromised. Continuous monitoring of suspicious keyboard simulation (e.g., via `keybd_event`) and child window enumeration can also help, though these techniques can be obfuscated. This detection approach parallels methods used for other Windows attacks, such as those involving Access Control List in Windows.
