### AI overview

Gravwell CEO Corey Thuen describes the "evil bit" he seeks in hacker hires as an adversarial instinct for finding ways to exploit systems, which he believes is difficult to teach. He argues that this mindset can serve defensive goals: he cites authorized work evaluating power-substation systems and compares hacking skills to tools whose consequences depend on users' motives. His career centered on industrial control system security and vulnerability research, and he says Gravwell's data analytics platform is intended to help defenders understand their own environments. The article also recounts a dispute over Southfork Security's Visdom tool: BEA alleged it derived from proprietary INL code; the case settled privately, with Visdom surrendered and Southfork wound down. No public trial resolved the allegations.

### AI overview

Rob Juncker, Mimecast's chief product and technology officer, recounts how his early curiosity about computers led to Basic programming and hacking, including unauthorized activity that earned him a warning. Studying computer science and economics helped redirect his skills toward protecting organizations, and he later held senior engineering and technology leadership roles at VMware, LANDesk, Ivanti and Code42.
