Details
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 one focuses on macOS osascript utility being used with an interactive Bash invocation, identified by the presence of
bash -iin the command line. Adversaries may abuse osascript and AppleScript's shell execution capabilities to launch interactive shells, establish remote access, or execute post-exploitation commands.
