Introduzione

L'agence fiscale française (DGFiP) a reconnu une fuite de données après qu'un pirate informatique se faisant appeler Zerobytes a volé 678 438 enregistrements concernant des contribuables. L'attaque, survenue le 12 juin, aurait été menée via un outil de recherche interne en utilisant un VPN. Bien que l'accès du pirate ait été coupé et qu'il n'ait pas pu récupérer l'intégralité des données, le fichier volé est proposé à la vente pour quelques milliers d'euros. La DGFiP a confirmé avoir immédiatement interrompu les comptes compromis, mais a reconnu que la sophistication de l'attaque avait empêché la détection initiale du vol. L'agence assure que les identifiants de connexion au site n'ont pas été compromis et annonce le déploiement de nouvelles mesures de sécurité. Les personnes affectées seront contactées individuellement la semaine prochaine pour être informées des données probablement consultées et des précautions à prendre. Cette fuite inquiète particulièrement les détenteurs de cryptomonnaies en France, qui redoutent une recrudescence d'attaques ciblées. Des appels, comme celui d'Alexandre Stachtchenko de Bitstack, demandent un moratoire sur la collecte de données par l'État jusqu'à ce que leur protection soit assurée, soulignant le droit fondamental à la vie privée. Ce incident survient dans un contexte où la France a déjà enregistré de nombreux cas d'enlèvements liés aux cryptomonnaies cette année.

Une nouvelle menace pèse sur les détenteurs de cryptomonnaies en France, car des malfaiteurs ont eu accès aux informations personnelles d'un grand nombre de contribuables.

Un pirate informatique utilisant le pseudonyme Zerobytes a réussi à dérober les données de 678 438 contribuables, extraites du site de la Direction Générale des Finances Publiques (DGFiP). Selon des rapports locaux, le malfaiteur affirme avoir réussi à pirater des serveurs internes en utilisant un outil de recherche interne via un VPN.

L'accès a été coupé au criminel, qui semble également avoir été impliqué dans des attaques précédentes contre des institutions françaises, et il n'a pas pu récupérer toutes les données des contribuables de la DGFiP. Néanmoins, le fichier est vendu à des parties intéressées pour quelques milliers d'euros.

La DGFiP a confirmé que l'attaque a eu lieu le 12 juin, soulignant qu'elle avait « immédiatement interrompu l'accès à tous les comptes utilisés dans les incidents identifiés », mais que « les mesures de contrôle d'accès prises dans ce cas n'ont pas permis de détecter que ces intrusions avaient conduit à un vol de données, en raison de la sophistication de l'attaque ».

L'administration a également précisé que les données nécessaires pour accéder au site n'avaient pas été compromises, et a annoncé la mise en œuvre de nouvelles mesures de sécurité pour prévenir de telles fuites à l'avenir.

« La semaine prochaine, la DGFiP contactera directement chacune des personnes physiques et des professionnels concernés. Ils recevront une information individualisée par courriel ou par courrier postal précisant les données qui ont probablement été consultées ou extraites, ainsi que, le cas échéant, les précautions à prendre », a conclu l'administration.

Les détenteurs français de cryptomonnaies ont exprimé leur inquiétude sur les réseaux sociaux, craignant que cette nouvelle fuite ne déclenche de nouvelles « attaques par clé » contre eux. La France est devenue un terreau fertile pour ce type de crimes après qu'un fonctionnaire des impôts aurait, selon les allégations, vendu des données sur des détenteurs de cryptomonnaies à haut statut.

Alexandre Stachtchenko, responsable de la stratégie et de la communication de l'entreprise Bitstack, a appelé à un moratoire sur la collecte de données personnelles par les institutions publiques, soulignant que la France a mis les contribuables en danger.

« Exigez un moratoire : arrêtez la collecte de données tant que l'État n'apprend pas à protéger ce qu'il détient. Contactez vos députés. Partagez cette information. Le droit à la vie privée est une liberté fondamentale qui doit être garantie », a-t-il souligné.

En avril, 88 personnes avaient été mises en examen en France dans 12 affaires d'enlèvements liés aux cryptomonnaies ; à cette date, 41 agressions avaient été enregistrées.

$2 Trillion: Countdown to AI's Largest IPO in History

The countdown for the largest IPO in AI history, a potential $2 trillion listing for Anthropic, is underway for October. The staggering valuation, reportedly projected by several investors, contrasts with the company's own internal restraint on setting a public target. Founded five years ago by former OpenAI core members, Anthropic's growth has been meteoric. Annual recurring revenue (ARR) surged from ~$9B in late 2025 to $47B by May 2026, with Q2 2026 revenue of $11.5B marking a 14x year-over-year increase. Bank valuations are even based on internal 2028 revenue forecasts of $190-200B. A key growth driver is Claude Code, its AI coding assistant. Its ARR quintupled in five months to $2.5B by February 2026, now constituting nearly 20% of total revenue. Surveys indicate Anthropic commands roughly 40% of enterprise LLM spending, doubling OpenAI's share in programming-specific use. However, alongside this explosive growth, reports detail significant internal cultural strife. Critics describe a divisive "priesthood" of PhD executives, led by CEO Dario Amodei, who promote a "save humanity" narrative that some employees find cult-like and alienating. This has reportedly created a demoralized workforce and a covert "underground network" of dissent among engineers torn between lucrative pre-IPO equity and a toxic work environment. Anthropic now faces a pivotal paradox: pursuing its mission of "safe" AI requires immense capital for compute, yet that capital demands relentless commercial growth. As it approaches its historic IPO, the company must navigate intense regulatory scrutiny, soaring operational costs, and internal tensions—any of which could destabilize its post-listing trajectory, much like SpaceX's significant post-IPO stock drop. The stage is set for a defining moment in tech history.

AI Boosting Efficiency and Cutting Costs Makes VC Increasingly Expensive

"AI for Cost Reduction Makes VC Funding More Expensive" Despite the "cost-reduction and efficiency" narrative of AI, venture capital (VC) investment in the AI sector is becoming increasingly costly. While AI tools lower the initial costs for many startups—with team sizes shrinking across funding stages—the market is polarizing. For top-tier AI teams, especially those from leading companies like Google and OpenAI, funding rounds are now larger and valuations are higher than ever at the seed and early stages. For example, new ventures by prominent researchers are securing billions in funding with valuations reaching tens of billions before having a mature product. This creates a "barbell" market: lightweight startups need less capital, while elite AI firms attract massive investments early on. This dynamic raises the cost for VCs to acquire and maintain meaningful ownership stakes. As valuations soar early, securing the same equity percentage requires significantly larger capital commitments. VCs must now invest more upfront and reserve substantial funds for follow-on rounds to avoid dilution, prompting large firms like Accel and a16z to raise massive new funds. Consequently, capital is concentrating intensely in a few perceived winners like OpenAI and Anthropic, widening the gap between large and small VC funds. While high valuations bake in future growth expectations, they also compress potential returns, demanding that portfolio companies achieve unprecedented scale. For major VCs, the core strategy is clear: secure early positions in potential winners and maintain the capital to keep investing as valuations rapidly escalate.

An Eight-Year Investment Takes a Sharp Turn: Why Did Ethereum Suddenly Abandon Poseidon?

On August 13, Ethereum researcher Justin Drake announced a significant shift in Ethereum's Layer-1 cryptographic roadmap: abandoning the SNARK-friendly hash function Poseidon in favor of traditional functions like SHA2 or BLAKE2. This decision ends eight years of research and investment, marking a major revision to the post-quantum security strategy. Poseidon, introduced in 2019, was highly efficient for zkRollups and zkVMs within SNARK circuits. However, its need for prolonged cryptanalysis and the pressing timeline for quantum resistance revealed limitations. Recent breakthroughs in SNARK design, specifically using binary fields, now enable traditional, battle-tested hash functions to perform as efficiently as Poseidon within SNARKs. Benchmarks show modern laptops can now verify over a million traditional hash calls per second. This change is partly driven by accelerated concerns over quantum computing threats. Reports warn that "Cryptographically Relevant Quantum Computers" could break current blockchain signatures like ECDSA by the early 2030s, risking trillions in assets. Ethereum's response focuses on hash-based post-quantum signature schemes, deemed more quantum-resistant than some lattice-based alternatives under pressure from AI cryptanalysis. Ethereum's updated post-quantum roadmap targets a production-ready "leanVM" for signature aggregation by 2027, with full deployment across consensus, execution, and data layers by 2028. The shift to mature hash functions like SHA2 reduces reliance on newer algorithms and aligns with the goal of using widely analyzed cryptographic primitives. Other major blockchains are also preparing. Solana's core teams have independently chosen the NIST-standardized Falcon signature scheme for its compact size. Starknet plans a phased migration, starting with replacing its Pedersen hash with BLAKE2. Ethereum's move signifies a strategic pivot towards proven security foundations for the quantum era.

Programmers Worldwide Are Wasting Money on Anthropic! The Company Can't Stand It Anymore

Anthropic recently published guidelines to help developers using Claude Code reduce unnecessary token costs. The key recommendations include: 1) Clear (/clear) conversations after completing a task to avoid carrying irrelevant file reads and command outputs into the next task. 2) Set the model and reasoning effort level at the start of a session, as switching mid-session invalidates the prompt cache, requiring a full-price recalculation of the entire dialog history. 3) Attach files using @ references instead of typing paths manually to avoid extra tool calls and searches that bloat the context. 4) Add quiet flags to verbose commands (e.g., in CLAUDE.md) to minimize lengthy output in the dialog history. 5) Use /compact while the session cache is still warm (before breaks) to compress the dialog at one-tenth the cost. 6) Offload large-output tasks to a sub-agent, which runs in an isolated context and only returns conclusions, preventing intermediate outputs from polluting the main dialog. The article explains token pricing: input tokens (prefill) are processed in parallel, while output tokens (decode) are generated serially, making output tokens five times more expensive. Caching is crucial for savings—if a request's prefix (system prompt, CLAUDE.md, dialog history) matches the previous one byte-for-byte, reading it costs only 10% of the standard input price. However, cache invalidation occurs when changing models, effort levels, fast mode, compressing dialogs, after cache expiration, or when resuming old sessions. Dialog history also grows quadratically (O(n²)) as file contents and command outputs accumulate, increasing costs per round. Proactive context management—like isolating noisy tasks, using /rewind to trim unproductive turns, and task-based session clearing—is becoming an essential skill for cost-effective AI-assisted development.

Pax Silica vs. WAICO: The US Wants to Prohibit Europe from Using Chinese Artificial Intelligence

The United States is preparing to demand that European and other partners abandon Chinese artificial intelligence initiatives, threatening exclusion from the American-led "Pax Silica" coalition, according to a leaked U.S. State Department document. This ultimatum forces signatories of the "AI Opportunity Statement" to choose between the Western technological ecosystem and alternative frameworks, with China not explicitly named but clearly targeted. Pax Silica is a U.S. strategy for AI and semiconductor hegemony, launched in late 2025. Its European presence expanded significantly in mid-2026. Concurrently, China, Russia, and 27 other nations established the World AI Cooperation Organization (WAICO) in July 2026 as an independent intergovernmental platform promoting AI governance based on UN principles. This situation creates a difficult choice, especially for European nations balancing strategic autonomy with dependence on U.S. tech and security. It also pressures Global South countries with pragmatic ties to both Washington and Beijing. The formation of competing blocks risks fragmenting the global tech landscape, forcing companies to split supply chains, increasing costs, and potentially leading to incompatible standards and protocols. The era of open globalization in AI may be ending, replaced by geopolitical confrontation where technological sovereignty trumps economic efficiency. The decisions made will shape the global digital economy for decades.
