This detection idea follows a research focused on the abuse of osascript on macOS. It is equivalent of cmd.exe on macOS, allowing to execute various commands, code pieces and scripts. And it is often abused by attackers.
This specific detection identifies network connections initiated by the osascript utility that remain open for 10 minutes or longer. Such prolonged network activity originating from osascript is atypical and may indicate malicious behavior, such as a connection to a command-and-control (C2) server.
