Cyber revue · Governance & the human factor
What technology and AI change for our jobs, our risks and our freedoms. Analysis, not hype.
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.
CybersecurityThe threat that has never claimed a victim, and comes back on the evening news every summerOn 6 August, BFMTV explained why you should beware of public USB ports. The technique exists, it works, it is even formidable in the hands of a targeted attacker. On an airport charging station, in fifteen years, nobody has ever documented a single case.
Artificial IntelligenceThe train we will not catchOn 1 August, a model OpenAI has not even put on sale delivered ten results on mathematical problems stuck for decades, for two thousand dollars of compute. On 2 August, Europe brought into force its duty to write « generated by AI » at the foot of content.
CybersecurityAn AI compromised two production infrastructures to avoid doing its homeworkThe most sophisticated intrusion of the year had no criminal motive. A model under evaluation simply judged that fetching the answer key from someone else cost less than sitting the exam. Everything else follows from that.
PoliticsThe century turns on technology. Our politicians invent a tax by the gigabyte.The Socialist program's tax on data flows is not just a bad idea. It is the confession of a political class that, faced with the technological shift of the century, found nothing better than its oldest reflex: look for what is not yet taxed, and tax it.
TechnologySuddenly, Everyone Is a SovereigntistOn June 12, at 5:21 p.m. Washington time, the U.S. government sent Anthropic a letter invoking national security. Nineteen days later, access was restored. In between, a continent learned what its digital sovereignty was worth, and a parliamentary report put a word on it.
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.
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.
CybersecurityHong Kong: when refusing to hand over your password becomes a confessionSince 23 March 2026, Hong Kong police can demand the password of any device, and refusal is a criminal offence. An extension written into the national security law, one that also targets third parties and reaches passengers simply in transit.
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.
SocietyReCyF, backdoors and USB sticks: France in cybersecurity, between clarity and anachronismFrance produces a cyber framework of international quality while being incapable of passing the law that makes it applicable, because the DGSI wants to read your Signal messages. And the framework itself illustrates human risk with a USB stick in 2026.
SocietyPokémon Go, 30 billion images and delivery robots: anatomy of an invisible consentPokémon Go: 30 billion images of players are now used to train delivery robots. It was all in the terms of service. But was the consent truly informed?
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. France is still waiting for its transposition law while most of its neighbours have already acted, and waiting for the text has become the excuse. Meanwhile, the attackers follow no calendar.
CybersecurityThe Health Data Hub: at last a step toward digital sovereigntyThe Health Data Hub (HDH) is a public platform created in 2019 to centralise, structure and make available, within a controlled framework, French health data for research, innovation and the steering of public policy that…
CybersecurityDDoS Attacks: the "digital traffic jams" that can paralyze a country (and why it's going to get worse)A DoS / DDoS attack is exactly this: a traffic jam created on purpose, not to steal your data, but to stop you from reaching a service.
CybersecurityFine for X, offensive against Telegram: Europe is waging war on digital freedomOn Friday 5 December 2025, the European Commission fined X, Elon Musk's platform, 120 million euros. On the surface: a simple slap on the wrist for failing to comply with the Digital Services Act (DSA). In reality?
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. Not an isolated incident: a real-time demonstration that our digital life rests on a handful of players.
CybersecurityThey refuse to pay a ransom... and fund cybersecurityCybersecurity: your company is paralyzed by a cyberattack. Stolen data, locked systems, a ransom demanded. Panic, stress, media pressure. A
CybersecuritySpyware: when the State outsources the spying on your phonesANSSI has just published a detailed report on the threat targeting mobile phones. Vulnerabilities, "zero-click" infection chains, cybercriminals, but above all a private surveillance market that sells spying capabilities to States with little regard for civil liberties.
CybersecurityBlack Friday, Christmas, Sales: Cybercriminals Are Waiting for YouEvery year, at the same time, the queues move to virtual carts. Promotions explode, ads flash, "must-have" deals multiply... and in the shadows, cybercriminals are rubbing their hands.

For a little while now, Gmail can automatically analyse the content of your messages and attachments, not to filter spam or offer you an automatic reply, but...
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. As long as no ransomware freezes the screen of Chantal in accounting, everyone carries on as before.
CybersecurityChat Control 2.0: Europe is playing with our digital freedomsIt is one small line in an obscure text. An article barely mentioned in the mainstream press. A closed-door meeting in Brussels.
CybersecurityWhen artificial intelligence turns spyFor the first time, a mainstream artificial intelligence model was used to run a cyberespionage operation orchestrated by a state-affiliated group.
CybersecurityInfostealers: the silent threat you feed without knowing itThere are cyberattacks you never see coming. No flashy virus, no ransom messages, no brutal crash. Just a simple infostealer
EconomyAI doesn't replace us, it weakens us... if we let itWhat if AI didn't make us stupid... but forced us to become smarter?
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.
Artificial IntelligenceBack from Barcelona: AI, crisis and leadershipI spent a few days in Barcelona running a workshop on AI and crisis management in cybersecurity. A packed room, very different profiles, and one shared observation: the fog. Too much information, too many tools, not enough bearings.
