Constructing an OS X Cyber Range for 
Red & Blue Teams

November 18th @ 14:00 - 15:00 (GMT +4) // HITB Track 2

There is an increasing number of threat actors attacking macOS – for example the state-sponsored APT28 utilized Trojan.MAC.APT2 to attack military and government organizations. Malware examples such as OSX.AppleJeus and OSX.NetWire.A are widely used by malicious actors to attack cryptocurrency exchanges. Although macOS is popular, we observed that research seldom discusses attack and defense techniques on macOS. As a result, both blue teams and red teams are not acquainted with macOS security, protection mechanisms and tools for investigations. A systematic survey of macOS attack and defense techniques is necessary, and a modularized cyber range for training red teams and blue teams would greatly improve the skills and experiences of the teams.

Our proposed system is composed of three fundamental components: an attack-defense association graph, a Go language-based red team emulation tool, and a toolkit for blue team performance evaluation. We demonstrate the effectiveness of our proposed cyber range with real-world scenarios, and believe it will stimulate more research innovations on threat analysis for macOS.
