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](/news/penetration-techniques-access-control-list-in-windows).
