In 2024, the breach at Snowflake's customer environments didn't exploit some exotic zero-day vulnerability. Threat actors simply used stolen credentials — many of them passwords reused across services without multi-factor authentication. Over 165 organizations were impacted, including Ticketmaster and AT&T. The lesson was brutal and
The Policy Everyone Signs and Nobody Reads In 2023, a single employee at a major casino operator plugged a personal USB device into a workstation. That device carried malware. Within hours, threat actors had lateral movement across the network. The resulting breach cost over $100 million in damages, downtime, and
In 2023, the FBI's Internet Crime Complaint Center received over 298,000 complaints about phishing scams — making it the most reported cybercrime category for the fifth consecutive year. The real number is almost certainly higher, because most incidents never get reported. I've spent years helping organizations
In 2023, a single compromised password at MGM Resorts helped threat actors trigger a social engineering attack that cost the company over $100 million.

The Textbook Got It Wrong In 2023, MGM Resorts lost roughly $100 million after a threat actor social-engineered their IT help desk with a single phone call. The attackers didn't exploit a zero-day vulnerability. They didn't write custom malware. They just talked their way in. If
In March 2024, a single compromised employee credential at Change Healthcare led to a ransomware attack that disrupted pharmacy operations across the United States for weeks. The attackers didn't kick down a digital door — they logged in. That's what account takeover looks like in practice, and
The Ransom Note Nobody Expected In January 2026, a mid-sized hospital network in the American Midwest discovered that every imaging workstation, patient scheduling system, and billing server had been encrypted overnight. The ransom demand: 200 Bitcoin. Staff resorted to paper charts and fax machines for eleven days. Surgeries were postponed.
In 2024, a finance clerk at a mid-sized manufacturing firm wired $25 million to a threat actor after joining a deepfake video call where every other "participant" — including the CFO — was AI-generated. The clerk wasn't careless. She wasn't stupid. She simply hadn't
The Breach That Started With "Summer2024!" In 2024, the Verizon Data Breach Investigations Report found that stolen credentials were involved in roughly 31% of all breaches over the prior decade — and that number hasn't meaningfully dropped. I've personally investigated incidents where an entire corporate
