Threats, leaks, ransomware, regulation: cybersecurity as it is actually lived, with no jargon and no FUD.
CybersecurityFrance's worst data breaches of 2026: the ranking (spoiler: you're in it)6,167 data breaches in 2025, a record, and 2026 is already doing better. From the Almerys brother-in-law nobody ever introduced you to, to the teenager who cracked open the ANTS vault by changing one digit in a URL, here is the ranking of France's worst breaches of the…
CybersecurityI can't listen to CISO podcasts anymoreYesterday I started one, I cut it off after eight minutes. I already knew everything. And the worst part is that I know exactly why it's like this, because I'm often on the other side of the mic, being a CISO myself.
CybersecurityMicrosoft held two opposite positions in a single week. That is the flaw.While the industry re-litigates responsible disclosure, a flaw that bypasses BitLocker is still sitting unpatched. And Microsoft, which wrote the rules of the game, just proved it only follows them when the mood takes it.
Artificial IntelligenceAttachment to an AI is not a quirk, it is a vulnerabilityAn AI director at Disney speaks to his software assistant as if to his son, and has handed it the rights to act in his place. The debate mocked the feeling and never saw the rights. Yet both vulnerabilities are dangerous, each in its own way.
Artificial IntelligenceVibe coding must not become the Wild WestVibe coding is brilliant, but most developers overlook two things that, without their knowing it, sink projects: compliance and security. How to ship AI-based applications that actually hold up.
CybersecurityMythos is no surprise. Here is what I was saying nine months ago.99% of the vulnerabilities Mythos found are still open. The patching debt does not date from April 2026, it just stopped being invisible.
CybersecurityCISA, the GitHub leak: when the watchdog leaves the keys in the doorCISA, the US cyber agency, exposed its own AWS GovCloud credentials on public GitHub for 6 months. Anatomy of a leak in 7 failures.

CybersecurityThe most cautious company in AI does not secure its own shared Claude chats.Anthropic denies public access to Mythos because it is too dangerous. Meanwhile, its own claude.ai domain serves as a phishing page through shared chats. The AI industry invests in spectacular risk and neglects the mundane risk.
CybersecurityThe ANTS hack: the 2007 flaw, the 2026 cheque, and the gap no figure can closeLecornu calls the ANTS breach the "heist of the century." It is a student homework-assignment heist. A 2007 flaw. With 200 million euros of announcement effect on top.
CybersecurityMythos changes nothing. And that is exactly the problem.Mythos finds thousands of flaws in code that has been shipping for twenty years. The real scandal is not the AI. It is that it takes a $20,000 AI to uncover what basic engineering practices should have prevented.
CybersecurityWhat nobody tells you when a hospital gets attacked.A French hospital takes two years to recover from a ransomware attack. 1,000 workstations, 200 applications, patient records lost forever. I lived through a ransomware attack in 2018. What makes me angry is not the attack.
CybersecurityAI and chatbots tell you you're right. That's the worst service they can do you.Chatbots are built to tell you you're right. Researchers at MIT have shown that even a perfectly rational reasoner falls into the trap. When your job is to spot what's wrong, that's a problem.
CybersecurityYou have 29 minutes. You are already losing 20 of them. And Mythos is not the problemYou are a CISO. It is 9:14 on a Tuesday morning. Your SIEM has just flagged a lateral movement alert. Twenty minutes later, you launch your first containment action. The attacker, meanwhile, needed only 29 minutes to move across your network.

CybersecurityCybersecurity: small businesses are not ready. And it will cost them.Talk to five owners of small businesses and you get the picture: cybersecurity is still a vague, distant, almost abstract idea.

CybersecurityWhy French SMEs are still stuck in 1980 (and why that's partly their own fault)Let me be blunt: you can't ask cybersecurity to move forward if some companies refuse to leave the minitel behind. And that's exactly what we still see today in most French SMEs. Yes, threats are evolving.
