France faces a new leak of sensitive data. A hacker claims to have extracted information concerning nearly 678,000 taxpayers following fraudulent access to the DGFiP system. Bercy confirms the intrusion and data exfiltration, but not this number yet. Individuals and professionals are among the potential victims.

The quantum threat pushes Ethereum to reconsider its cryptographic choices. Poseidon, long considered as a hash function suitable for zero-knowledge proofs and the post-quantum era, has just been discarded by the network's researchers. Behind this change lies much more than an algorithm choice. Thus, Ethereum is revising the cryptographic foundations of its future architecture. A new approach now promises better performance, enhanced auditability, and safer integration. It remains to understand why Poseidon lost the race, what gains its replacement offers, and at what pace this transition could reach the network.

In France, the crypto threat no longer stops at the screens. In the Somme, a young couple suffered three home invasions for cryptos they claim never owned. The origin of this nightmare: compromised personal data, exploited by criminals convinced they would find a crypto wallet at their victims' homes. Recruitment of executors, violence, extortion: the case reveals how a digital leak can lead to a physical attack. After the verdict from the Amiens court, the couple now considers a radical decision: selling their house to flee.

OpenAI has just suspended the internal development of Astra, its future artificial intelligence model. Indeed, its capabilities in offensive cybersecurity and code generation have crossed a threshold that teams no longer consider controllable. For the digital ecosystem, this decision sounds like a warning. At a time when financial infrastructures, blockchain, and decentralized protocols rely on the reliability of code, the AI race now progresses faster than the measures meant to regulate it.

Coldcard, Bitcoin's safest vault, turned into a sieve. Result: $100 million gone and a million addresses fleeing. Self-custody has some kinks to iron out.

Quantum computing is no longer a theoretical threat to cryptos. As tech giants accelerate their advances, the cryptographic resistance of blockchains becomes an immediate issue for investors, financial institutions, and developers. Recent warnings from several major industry figures have reignited the debate over decentralized networks' ability to face this technological disruption. Amid technical disagreements, industrial urgency, and market concerns, the crypto ecosystem faces one of the greatest challenges in its history.

In 27 hours, 16 developers reported 4,962 issues in 390 Bitcoin-related projects, including 85 critical vulnerabilities and 635 high-severity ones. Sixteen developers guided the audit using AI models and about 10,000 dollars of computing power per day, but the volume mainly reveals a triage problem. The priority is now to handle bugs before attackers.

$350,000 worth of crypto stolen from a miner: a former cop receives life imprisonment plus 15 years. The details of this shocking case.

Cold storage, long presented as the ultimate bulwark against hacking, has just suffered one of its biggest setbacks. A critical software vulnerability affecting Coldcard wallets enabled the theft of tens of millions of dollars in bitcoin, reviving questions about the limits of self-custody. This case breaks out as the market comes off a July up 7.36%, under pressure from massive institutional withdrawals and approaching two major protocol upgrades expected in August.

Pavel Durov rejects the "terrorist" label that Russia just assigned to him. The founder of Telegram states that Moscow is sanctioning him mainly for refusing mass surveillance and censorship on the platform.

Russia toughens its stance against Telegram: its founder Pavel Durov indicted for "aiding terrorism." All details in this article!

The crypto industry is going through its worst semester against hackers. Ethereum and Solana account for record losses. Full analysis.

North Korean authorities have arrested a group of former cyber operators and IT specialists accused of hacking two public banks and laundering funds via cryptocurrencies. South Korean media Daily NK revealed the case on July 25, citing an anonymous source in Pyongyang. A case that disrupts the usual narrative of North Korean cyberattacks, which were until now systematically directed outward.

The cryptocurrency sector continues to attract cybercriminals, who perfect their methods to deceive their victims. This time, Kaspersky highlights a new malware framework designed to compromise digital wallets and steal sensitive data. Analysis shows attackers combine social engineering, fake GitHub projects, and remote access techniques to infiltrate devices. Meanwhile, another campaign targets Web3 developers through fake job offers posted on LinkedIn, revealing an evolution of threats.

The Blockchain company Consensys accidentally employed a developer linked to North Korea, who accessed some of its systems for a month. The incident, revealed on July 17, 2026, did not result in any theft of funds or malicious code according to the company. How far do North Korean networks infiltrate development teams in the sector?

The inexorable advance of cutting-edge quantum computing poses an existential threat to blockchain security, forcing the ecosystem to revise its cryptographic foundations. Preserving inactive Bitcoin wallets against machines capable of breaking private keys is a critical priority. On July 16, Project Eleven unveiled a post-quantum cryptographic proof proposal to address the "Q-Day" challenge. By replacing signature validation with lineage verification, this protocol offers an unexpected safety net.

OpenAI presented on Wednesday, July 15, 2026, an automated red-teaming tool named GPT-Red, tasked with strengthening GPT-5.6's resistance to prompt injection attacks. The concept starts from a simple observation: human intrusion testing methods no longer keep pace with the models' capabilities. The challenge is now growing, as these vulnerabilities directly affect the security of autonomous agents.

The European Parliament has paved the way for the extension of Chat Control until 2028. This regime allows platforms to voluntarily scan certain private communications to detect child sexual abuse content. The text however rekindles a central battle in Europe: protecting children without weakening encryption and privacy.

The Ethereum Foundation is shifting paradigms and automating its cyber defense. Its « Protocol Security » unit now deploys swarms of autonomous AI agents to continuously attack its own network. The goal is to track, exploit, and fix vulnerabilities before hackers do. This initiative, revealed by the protocol's security team, marks a major technological breakthrough at a time when the slightest flaw in a smart contract can lead to losses of hundreds of millions of dollars.

The EU Parliament revives the vote on the Chat Control text. This rekindles concerns about the confidentiality of private messages.

Donald Trump signs two decrees to accelerate quantum computing in the United States. What this means for the crypto universe.

The National Cybersecurity Agency of France (ANSSI) has just laid the foundations for a mandatory transition to post-quantum cryptography, cementing a threat that many still thought was distant. This decision is crucial because it represents the tipping point between theoretical research and legal obligation, requiring critical infrastructures and the crypto industry to hasten their own technological transformation.

The arrival of autonomous agents is evolving the very notion of sovereignty and infrastructures in the digital age. Faced with a rise in technology often faster than old rules, it becomes essential to give a legal existence to algorithmic entities. Estonia, a pioneer in innovative institutions and 100% digital, confirms once again as the global laboratory of this transition. By granting an official status to artificial intelligences, the Baltic state traces a new path in the history of technological governance.

Zcash dodged a bullet with a bug buried deep in its guts, but the coin bounced back like a jack-in-the-box. The short sellers? They got wrecked.

The security of a blockchain relies on a simple promise: making the cost of an attack far greater than the expected benefit. This equation has held for over ten years thanks to cryptographic mechanisms considered solid. Yet quantum computing is beginning to shake everything up. The machines that could threaten bitcoin or Ethereum do not yet exist, but progress already made in this field forces developers to prepare for the future. A proposal presented by Nicolas Consigny, manager of the Kohaku project at the Ethereum Foundation, indicates that Ethereum could start protecting its accounts against quantum attacks today for a trivial amount: only 7 cents per account.

Zcash had a close call, a very close call, with a four-year-old bug hidden in its secret circuit. Claude Mythos came through and found nothing else. Phew.
