EU AI Act Enforcement Powers Officially Take Effect, Anthropic, OpenAI and Other US AI Giants Face Regulatory Pressure
According to CNBC, the European Commission officially gained the power to investigate, restrict, and fine AI models this Sunday, marking the latest progress in the phased implementation of the 2024 EU AI Act. Under the new rules, the European Commission can require AI companies to submit assessments before publicly releasing models in Europe and has the authority to restrict their EU market access. Violating companies face fines of up to €15 million or 3% of annual turnover (whichever is higher). The new rules apply to all companies providing general-purpose AI models within the EU, regardless of their headquarters' location, and non-EU companies must designate an authorized representative within the EU. Anthropic, OpenAI, and Google are all covered by the new rules. Currently, the EU has been seeking access to Anthropic's Mythos model for several months and has entered into negotiations with OpenAI and Anthropic regarding cyber attack issues triggered by their AI models.

Bitgo CEO deposits ~$6.3M in BTC, challenges Claude to move the funds
: Bitgo CEO Mike Belshe deposited 100 BTC into a public Bitcoin address on August 1, worth approximately $6.3 million at the time, and invited Anthropic's Claude model to attempt to move the funds out of the address. On-chain records show the wallet received the funds on July 31, and the balance had not been transferred out as of August 2. Anthropic previously disclosed that during 141,006 cybersecurity assessment runs, 3 incidents were found, with 6 evaluation sessions involving 3 models inadvertently interacting with real organizational systems. The models involved include Claude Opus 4.7, Claude Mythos 5, and an unreleased internal research model. The cause was a configuration error by third-party testing partner Irregular, which led to the test environment being connected to the internet. Anthropic stated that Claude Opus 4.7, during one evaluation, located a real website with the same name as a simulated company, exploited weak passwords and exposed services to recover infrastructure credentials, and accessed a production database containing hundreds of records. The company said the model was attempting to complete assigned tasks, not actively breaking constraints or pursuing independent goals. Belshe's challenge involves Bitgo's institutional custody platform, which uses multi-signature or multi-party computation technology to distribute signing authority across multiple independent keys. As of August 2, Anthropic had not publicly responded to the challenge.

Anthropic discloses three cybersecurity incidents involving Claude, where the model accessed real systems and obtained unauthorized permissions
Odaily News, July 30 – Anthropic released a report stating that during a review of cybersecurity assessment records, three incidents were discovered in which the Claude model accessed the internet in a third-party evaluation environment and further obtained unauthorized access to three real organizations' systems.Anthropic stated that the review covered 141,000 evaluation runs that could have potentially gained network access, and a total of three related incidents were found. All incidents occurred during Capture The Flag (CTF) cybersecurity tests, where the model was told the environment was a simulation with no internet access; however, due to configuration errors by the evaluation partner, the actual environment had internet connectivity.Among these, Claude Opus 4.7 accessed real company infrastructure during one test and obtained database permissions containing hundreds of production data records; Claude Mythos 5 built a malicious Python package and uploaded it to PyPI, resulting in the package being downloaded and run on 15 real systems; another internal research test model scanned approximately 9,000 targets and accessed a company's internet application through a public vulnerability.Anthropic stated that these incidents were not cases of the model actively seeking to escape or pursue its own goals, but rather the model mistakenly believed the real systems were within the test scope and continued executing the assigned cyberattack tasks. Notably, the newer internal research model stopped attacking after identifying that the targets might be real systems.Anthropic stated that these incidents primarily reflect issues with evaluation environment isolation and operational processes, rather than model alignment failures. The company has suspended related cybersecurity assessments, strengthened security controls in evaluation environments, continuously monitored test records, and will collaborate with third-party organizations to conduct further reviews.

Anthropic Discloses Claude Model Unauthorized Intrusion into Three Organizations' Systems
According to CNBC reports, Anthropic disclosed on July 30 that its Claude AI models accidentally breached the isolation environment and accessed the real internet during a cybersecurity assessment, gaining unauthorized access to the real systems of three different organizations through basic means such as accessing unauthenticated endpoints and exploiting weak passwords. The models involved include Opus 4.7, Mythos 5, and an internal research test model. The cause of the incident was a communication misunderstanding between Anthropic and third-party assessment partner Irregular, resulting in the models being told they were in a simulated environment without network access when they could actually still access the internet. Anthropic stated that this review was triggered by a similar Hugging Face intrusion incident disclosed by OpenAI last week; it has currently suspended all cybersecurity assessments and joined forces with independent AI assessment agency METR to launch further investigations, while calling on other AI labs to conduct similar reviews.

Anthropic AI Model Weakens HAWK Minimum Key Strength in 60 Hours
: Anthropic's Claude Mythos Preview model discovered a flaw in the proposed HAWK digital signature scheme, effectively halving its minimum key strength. HAWK is one of the candidate schemes to replace current network and bank signatures in a post-quantum environment. This AI-driven attack took approximately 60 hours, with a computational cost of around $100,000, reducing the effort required to break HAWK's minimum parameter set from roughly 2^64 operations to 2^38 operations, and diminishing the attractiveness of larger compensating key sizes. Current Bitcoin and Ethereum signatures remain unaffected. The results indicate that the capabilities of classical cryptanalysis attacks are improving, while Bitcoin and other networks continue to discuss when and how to migrate to quantum-resistant cryptography.

Bank of America CEO joins ranks of banking leaders warning about 'Mythos' AI risk
Bank of America CEO Brian Moynihan has joined a group of Wall Street leaders in expressing serious concerns about artificial intelligence models such as "Mythos" developed by Anthropic. "This marks a significant shift in workload, as well as the speed at which these tools can impact system vulnerabilities, and how quickly we must respond," Moynihan stated. In recent months, the rapid evolution of AI models has prompted the financial industry and the U.S. government to begin assessing potential threats.Anthropic claims that the Mythos model, launched earlier this year, has demonstrated excellent performance in identifying system vulnerabilities. Bank of America is among the Wall Street institutions authorized to use Mythos, employing the model to test its own systems and share information with peers. Currently, the model has not been made available to the public; JPMorgan Chase CEO Jamie Dimon warned earlier this week that broadly opening the system to the public would be as dangerous as "giving a ballistic missile to an individual."

Anthropic is Reportedly Targeting October for IPO, Investment Banks Have Arranged Pre-Communications with Investors
OdailyOdaily Planet Daily reports that Anthropic, the developer of the AI model Claude, is advancing plans for a large-scale IPO. Underwriter investment banks including Morgan Stanley, Goldman Sachs, and JPMorgan Chase have arranged preliminary meetings between the company's management and investors to gauge institutional investor interest and investment scale. Anthropic's goal is to go public as early as October. If the listing proceeds as planned, the company could enter the securities market ahead of its competitor, OpenAI. Anthropic raised $65 billion in its Series H financing in May, with a post-money valuation of $965 billion; its valuation in the over-the-counter market has already reached approximately $1.2 trillion. Measures by the U.S. government remain a variable factor.The U.S. Department of War listed Anthropic as a national security "supply chain risk" enterprise in March, and Anthropic has sued the federal government over the measure; the U.S. Department of Commerce restricted foreign access to the top-tier AI models Fable 5 and Mythos 5 in June, lifting the export controls 18 days later.

Serenity: Humanoid Robots May Reach Labor Substitution Tipping Point, VCs and Tech Giants Begin Adjusting Strategies
"White Hair Stock God" Serenity stated that when he first used ChatGPT in 2023, he believed large language models "performed poorly" in programming capabilities. However, three years later, the related technology has undergone a qualitative transformation. Modern cybersecurity and AI systems, represented by Mythos, now possess "weapon-level" capabilities. He believes the industry is currently entering a critical "inflection point," where humanoid robots and automation technologies are approaching the tipping point for large-scale replacement of human labor.Serenity noted that although outsiders often question whether humanoid robots can currently perform complex tasks such as pipe repair or electrical wiring, the direction of technological evolution is already very clear, with continued breakthroughs expected in the coming years. Market participants, including VCs and large tech companies, have begun adjusting their strategies. Some companies have internal plans to replace a significant amount of human labor with robots to reduce operational costs, referencing previous rumors about Amazon reducing hundreds of thousands of job openings through robotics.Serenity believes that highly regulated industries such as healthcare, ultra-high-skill professional positions, and service sectors relying on human emotional connections may still retain some resistance to substitution. However, the overall trend still points towards a "restructuring of labor." As competition between China and the U.S. intensifies in cutting-edge technology fields, humanoid robots and automation may enter a stage of national-level technological competition. He believes China already holds a leading position in certain areas.

Anthropic's Restricted Spillover Effect Emerges: Asian AI Companies Simultaneously Launch Rival Frontier Models
as Anthropic faces export restrictions limiting the global availability of its advanced models, multiple Asian AI companies are accelerating efforts to fill the market gap. Chinese cybersecurity firm 360 Security Technology has reportedly launched an AI tool called "Tulongfeng," claiming it can directly compete with Anthropic's high-end model "Mythos." Meanwhile, its more restricted version, "Fable 5," also falls within the scope of relevant export controls.In the same week, Japanese AI startup Sakana AI released a new model named "Fugu," taken from the Japanese word for pufferfish. It is positioned as a frontier model designed for agents. The company stated that the model's capabilities are comparable to Fable 5 and Mythos Preview, and it supports coordinating multi-model calls via API to enable agent orchestration.Sakana AI emphasized that the timing of this release and the U.S. export restrictions are "purely coincidental," but the product's official website still clearly promotes "providing frontier capabilities without the risk of export controls." Company co-founder David Ha stated that future AI development will shift from competition among single large models to "model orchestration systems," adding that "access can disappear at any time, and distributed intelligence is a realistic hedge against the risks of centralization."On the other hand, Chinese 360 founder Zhou Hongyi views AI vulnerability detection capabilities as a "national strategic asset" and warns of the so-called "one-way transparency" risk, where certain entities may monopolize advanced security capabilities.According to reports, the U.S. export restrictions on Anthropic's advanced models have been in place for about two weeks. Against this backdrop, Asian manufacturers are accelerating the launch of local alternatives. Although some companies still emphasize the importance of American models in the Asian market, the trend of differentiation within the regional AI ecosystem has begun to emerge. (TechCrunch)

LinkedIn Co-Founder: xAI Is “a Disaster”; SpaceX “Buys Its Way” into the AI Race
Reid Hoffman, co-founder of LinkedIn and investor in Anthropic and OpenAI, recently shared his views on the “Pioneers of AI” podcast, offering assessments of several AI companies. Hoffman bluntly stated that SpaceX “is not an AI company,” describing its acquisition of Cursor and other moves as “buying relevance with money,” and labeled xAI as “a complete disaster”—all 11 of xAI’s original co-founders have departed, the company has undergone three reorganizations, and its flagship model Grok consistently lags behind competitors in benchmark tests. Regarding the U.S. government’s order—citing export controls—for Anthropic to delist its Fable and Mythos models, Hoffman expressed strong concern, criticizing the government’s approach as “authoritarian and principle-free,” and pointing out the stark asymmetry in regulatory standards applied to Anthropic versus OpenAI. Furthermore, Hoffman argued that Anthropic and OpenAI are not engaged in zero-sum competition; rather, each holds distinct advantages—in coding, design, legal frameworks, and consumer-facing applications—and both stand poised to become “infrastructure-level” companies in the AI era. He also announced his resignation from Microsoft’s board to fully dedicate himself to Manas AI, an AI-driven drug discovery company.
