A school district in Arizona lost $3.5 million in January 2024 after a single employee followed spoofed wire transfer instructions. The attacker didn't exploit a software vulnerability. They exploited trust. That incident captures why most computer security advice fails — it focuses on tools while ignoring the human
The Breach That Started With "Spring2024!" In 2023, a Verizon Data Breach Investigations Report finding shook the industry: roughly 49% of breaches involved stolen credentials. Not sophisticated zero-day exploits. Not nation-state malware. Passwords. Reused, predictable, phishable passwords. I've responded to incidents where the root cause was
In January 2024, Microsoft disclosed that a Russian state-sponsored threat actor — Midnight Blizzard — breached corporate email accounts by exploiting a legacy test tenant that lacked multi-factor authentication. No zero-day exploit. No sophisticated malware. Just a password spray against a forgotten cloud account. That single oversight gave attackers months of access
The Breach That Changed How I Think About Cybersecurity In February 2024, Change Healthcare suffered a ransomware attack that disrupted pharmacy operations and medical claims processing across the entire United States. UnitedHealth Group later confirmed that roughly one-third of all Americans may have had their data exposed. The attack vector?
In 2023, MGM Resorts lost an estimated $100 million after a threat actor socially engineered an IT help desk employee with a single phone call. That one incident tells you more about what cybersecurity actually is — and isn't — than any textbook ever could. If you've ever
In January 2024, a massive credential stuffing attack compromised over 34,000 PayPal accounts — not because PayPal's systems failed, but because users reused passwords across multiple sites. The attackers didn't hack anything. They simply tried stolen credentials from other breaches and walked right in. If you&
In 2023, the FBI's IC3 received over 21,000 complaints related to malware infections that led directly to credential theft — and a significant number of those involved keyloggers silently recording every password, credit card number, and private message typed on a compromised machine. A keylogger attack doesn'
In 2023, the FBI's Internet Crime Complaint Center received over 880,000 complaints with losses exceeding $12.5 billion — a 22% increase from the prior year. A significant portion of those complaints involved malware, ransomware, and credential theft that started with a single computer virus. If you think
In 2024, the Verizon Data Breach Investigations Report found that stolen credentials were involved in roughly 31% of all breaches over the prior decade. That number hasn't budged much. I've worked incident response cases where a single reused password — a seven-character string an employee used on
In 2024, a finance team at a mid-size logistics company wired $25 million to a threat actor who impersonated their CFO on a deepfake video call. Every person on that call had passed their company's annual security training. Every single one. That's the gap between checking
