FireEye’s Innovation and Custom Engineering (ICE) team released a tool today called GoCrack that allows red teams to efficiently manage password cracking tasks across multiple GPU servers by providing an easy-to-use, web-based real-time UI (Figure 1 shows the dashboard) to create, view, and manage tasks. Simply deploy a GoCrack server along with a worker on every GPU/CPU capable machine and the system will automatically distribute tasks across those GPU/CPU machines.
