So far this year, I’ve been diving deep into the real cost of cyber failures—not just in dollars, but in reputation, security, and sheer chaos. And let’s be honest, some of these breaches read like cybersecurity horror stories mixed with a bit of corporate drama.

📌 2013 Target Cyber Incident Case Study – The breach that made every holiday shopper paranoid. Hackers slipped in through a HVAC vendor (yes, really) and walked out with 40 million credit card numbers. Nothing says “Merry Christmas” like a massive fraud spree.

🎥 2014 Sony Pictures Hack – The ultimate Hollywood cyber thriller, starring leaked emails, embarrassing secrets, and a North Korean cyber onslaught over The Interview. The world learned that bad cybersecurity hygiene is worse than bad PR.

🔐 2015 The $217 Million OPM Hack – When 21.5 million sensitive government records (including fingerprints) end up in the wrong hands, it’s more than just a breach—it’s a national security nightmare. I broke down how the attackers followed the Lockheed Martin Cyber Kill Chain step by step, and let’s just say… it was way too easy.

What’s the lesson? Cybersecurity is never just an IT problem—it’s a business, reputation, and national security problem.

Hi, I’m Chris Nadeau. I started this site back in 2015 to share knowledge as I advanced my education in networks, hacking, and security. After a few years of posting, I found that I didn’t have as much time to contribute, as I had shifted my focus to studying leadership.

Now that it’s 2025, I’ve decided it’s the perfect time to resume personal research projects and start writing again. This year, my primary focus for knowledge-sharing will be my research into a decade of cybersecurity incidents. My goal is to dive into one major breach per month, sharing my findings from a business impact perspective. Beyond the initial breach notification and post-breach reporting, I plan to explore the total costs and the revenue impacts on businesses.
