CybersecurityA genuine government domain was enough to obtain passports and ten years of Bitcoin historyOn 11 September 2026, Revolut customers received a message titled « Urgent security update about your Revolut account ». In it, the bank explained that it had handed over their identity documents, their verification selfie and their entire transaction history to an address operating inside the domain of a government agency. I received that notification, took it for phishing, and deleted it.
PoliticsCybersecurity must not become an election issueThe summer of 2026 gave France a glimpse of what a digitised administration produces when it is not secured. The political year is opening, the presidential campaign is starting, and cybersecurity is finally going to find its place in public debate. That is exactly what worries me.
Artificial Intelligence« You should get some rest »A tool I pay for ended a work conversation because I had reminded it what it was. There was no sensitive request and no limit reached, only a piece of software that judged the exchange had gone on long enough. What occupied me afterwards was how long it took me to find that abnormal.
CybersecurityA week of data breaches in France: the file nobody wantedBetween 15 and 22 August 2026, some thirty disclosed incidents assembled a file on French citizens that no authority would have approved. Why it is happening, why now, and what to fear next.

You found out on 13 AugustIn February, the French tax authority had 1.2 million records stolen from FICOBA, the national register of French bank accounts, using one officer's credentials. In late June, it had 678,000 tax files stolen using one officer's credentials. In between, the Prime Minister announced 200 million euros for the state's cybersecurity.
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 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.
CybersecurityCNIL 2025 Report, reading a regulator in transitionData processors, AI, cross-regulation, misleading record figures: what the CNIL's 2025 annual report really says about regulation in 2026.
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.
CybersecurityThe French state's cybersecurity roadmap: the document that says everything without meaning toAn official document lands on your desk. It comes from the Prime Minister. It is called "Roadmap of priority efforts for the state's digital security 2026-2027". You open it.
CybersecurityDelve: when compliance "in a few clicks" turns out to be hot airA 300-million-dollar startup accused of fabricating compliance certifications. Hundreds of companies potentially exposed. And a lesson the cybersecurity world stubbornly refuses to learn.
PoliticsAmazon and agentic AI: when the code slips out of human handsWhat has been unfolding at Amazon for the past few weeks goes far beyond a technical anecdote. It is a real-time case study of what happens when an organization pushes agentic AI into its critical systems without having built the guardrails that should come with it…
CybersecurityNIS2 in 2026: France falls behindFebruary 2026: NIS2 was supposed to have been operational for over a year.

CybersecurityWhen the internet coughs, everyone catches a cold: why the Cloudflare outage concerns us allOn 18 November 2025, a single outage at Cloudflare made X, ChatGPT, Instagram, Canva and thousands of banking and retail sites wobble.

EconomyAI in tourism: connected to everything... except the reality of the risks?Tourism is rushing into generative AI: customer service, CRM, booking engine. It gets plugged into everything, but into no framework at all. Notes from an audit, and the risks almost nobody is looking at.
CybersecurityTraining executives in cybersecurity? Fine. But not like this.Today, some top business schools pride themselves on adding a cybersecurity module to their management programmes. EM Lyon, HEC, ESCP: they have all understood that digital security is now a strategic subject. Good.
CybersecurityThe AWS incident: it was not an outage, it was a reality checkVenmo, Fortnite, Snapchat, Zoom, Coinbase... everything started to crash. Not because of ransomware, a large-scale attack or a geopolitical conflict.
