Episode 11: The Cybersecurity Wake-Up Call Private Markets Can't Afford to Ignore

Ray Mitchell has seen it all from the front lines. As CISO of Sigma Information Group, he gets the calls nobody wants to make — companies that just got hit with ransomware, funds that wired money to a fraudster, executives whose email was silently compromised for months before anyone noticed.

In this episode, Ray joins host Mike Langford and 6lock CEO Todd Sorrel for a conversation that's equal parts eye-opening and practical. Ray breaks down exactly how attacks happen — from the 800-pound gorilla nobody wants to deal with (email) to double extortion ransomware to AI-powered voice cloning that can fool every single person in your office. He also shares what firms are still getting catastrophically wrong, the two security measures that stop 99% of account takeovers, and why your most vulnerable link might not be inside your firm at all.

In this episode:

• Why bad actors go to work every day with a suitcase — and have performance reviews
• The sales meeting where Sigma's prospect got hacked in real time, mid-pitch
• Email is still the 800-pound gorilla — and most firms are running payments straight through it
• Phishing-resistant MFA and trusted device enrollment: the two things that actually work
• How Ray's team used an AI voice agent to trick client employees — and what it revealed
• The pizza place hack: why attackers always go after the weaker link
• Double extortion ransomware, whether to pay, and what to have in place before it happens
• "Data is the new oil" — and what that means for how you use AI in your business today
