first_img OpenAI's new model Astra can autonomously discover and exploit software vulnerabilities, rated as "critical" in cybersecurity capability level

OpenAI stated that its upcoming Astra model can autonomously discover previously unknown software vulnerabilities and convert them into usable attack vectors without human intervention, making it the company's first model to reach the "Critical" cybersecurity capability level threshold. In a blog post released on Tuesday, OpenAI mentioned that according to its Preparedness Framework, reaching this level means the model can discover zero-day vulnerabilities and develop usable exploit code in hardened real systems without human involvement, or design and execute attacks based solely on a high-level objective.In testing, Astra achieved a 100% score in benchmark tests for developing exploit code based on known vulnerabilities and discovered two previously unknown vulnerabilities in another internal test. Additionally, the model successfully broke through a hardened browser sandbox and executed commands on the host machine, while gaining root access by exploiting multiple weaknesses in the operating system. OpenAI stated that it has delayed some of Astra's development progress to enhance security measures and plans to make its advanced cybersecurity capabilities available only to selected testers.This capability is particularly relevant to the cryptocurrency industry, as software vulnerabilities can be converted into financial losses within minutes. CoinDesk reported in June that increasingly powerful AI models can compress the process of searching code, discovering misconfigurations, and assembling attacks from days or weeks to machine speed. Security researchers noted at the time that the significant change was not the emergence of new categories of attacks, but rather the dramatically increased speed at which existing vulnerabilities are discovered and exploited.

Strategy invested nearly $370 million to purchase 4,603 BTC, and BitMine has continuously increased its holdings of Ethereum for 65 weeks

According to BBX data, last week, publicly listed companies in the U.S. disclosed their latest real accounts regarding digital asset treasury allocation and leverage increases, with the core dynamics as follows:Strategy (NASDAQ: $MSTR) invested $369.7 million to increase its holdings by 4,603 BTC: According to the latest 8-K filing submitted by Strategy, the company purchased 4,603 bitcoins between August 24 and 30, 2026, at an average price of approximately $80,318. The funds for this purchase came from its stock ATM program (during the same period, 4.5314 million shares of MSTR common stock were sold, raising approximately $602.8 million). Of the raised funds, $151.8 million was used to repurchase 1.5572 million shares of STRC preferred stock, and $50.7 million was used for dividend payments. As of August 30, Strategy's cumulative holdings reached 845,050 BTC (total cost approximately $63.73 billion, average price approximately $75,412).Strive increased its holdings by 1,800 bitcoins, with total holdings surpassing 23,000: According to the 8-K filing submitted by Strive to the SEC, the company purchased 1,800 bitcoins between August 24 and 28 at an average price of approximately $79,431. As of August 28, Strive's total bitcoin holdings increased to 23,156 BTC. In addition, its balance sheet also holds 505,000 shares of Strategy STRC preferred stock (fair value approximately $49.15 million) and about $183.5 million in cash.BitMine has increased its holdings for 65 consecutive weeks, with Ethereum holdings soaring to 5.9 million: Nasdaq-listed company BitMine disclosed that it increased its holdings by another 53,501 Ethereum last week, achieving a remarkable 65 consecutive weeks of increases. As of August 30, its total Ethereum holdings reached 5,901,112 ETH (approximately 4.9% of the total supply on the network). Currently, the total value of the company's crypto assets and various investments is as high as $15.6 billion, with the number of staked Ethereum remaining at 5,067,309 (accounting for 86% of total holdings), corresponding to a value of approximately $12.7 billion, and the current annualized staking yield is approximately $335 million.

first_img Polygon has fixed security vulnerabilities through two hard forks, which were previously deployed privately

Polygon Labs disclosed that it has fixed a batch of security vulnerabilities in its proof-of-stake network through two hard forks, with the related fixes privately deployed before public disclosure. According to a forum post released on Wednesday, the team packaged the fixes into the Austin hard fork of the Bor client and the Kyoto hard fork of the Heimdall client, both of which followed the standard process for fixing issues that affect consensus: first validated on the Amoy testnet, and then publicly disclosed once the mainnet was activated and the network was secure.The Austin fork fixed two denial-of-service paths in block processing, including a vulnerability where malicious block producers could crash peer nodes by filling them with oversized field data. The Kyoto fork addressed a broader range of consensus hardening issues, with the most severe vulnerability allowing an attacker to force the entire validator set to perform costly and coordinated work with just one crafted transaction—the cost of constructing the transaction is low, but the network processing cost is high. Polygon emphasized that none of the vulnerabilities were observed to be exploited on the mainnet and have been proactively addressed. The two upgrades are now mandatory for node operators and have taken effect without the need for state migration or resynchronization.This disclosure comes at a critical transformation period for Polygon, which has completed the migration of the traditional MATIC token to POL as part of a comprehensive overhaul of its network architecture. The news did not boost the price of POL; according to CoinGecko data, POL traded at approximately $0.09983 on Sunday, down 2.3% in 24 hours, down about 6.8% over the past week, and down about 60.8% over the past year, with a market capitalization of approximately $1.07 billion.

According to the SpaceX stock unlocking arrangement, Gate will simultaneously support the unlocking of Pre-IPO (stock) shares

According to the SpaceX stock unlocking schedule, the first batch of shares for Gate Pre-IPOs project SpaceX (SPCX) will be unlocked on August 26 at 20:00 (UTC+8). The total amount of the first batch to be unlocked is 33,900 SPCX, with 20% of the shares being unlocked based on the actual holdings at the time of the user’s spot account snapshot, and the corresponding shares will be directly credited to the Gate stock account at a 1:1 ratio.Gate is the first platform in the industry to support Pre-IPO share unlocking and directly distribute listed company stocks to users. This unlocking includes SPCX that users previously acquired and held through Pre-IPOs, as well as SPCX purchased subsequently; SPCX that has been sold will not be included in this round of unlocking. Users need to check their SPCX holdings and open orders in advance to ensure that the SPCX used for this unlocking is in an available state.Gate will continue to provide users with an asset participation experience from Pre-IPOs subscription before listing, internal trading, to stock unlocking entering the U.S. stock market. This is the first 20% stock unlocking for SpaceX (SPCX), and the remaining portion will be processed according to the unlocking rules of the target company as soon as possible, subject to the official announcement from Gate.

Market volatility and capital differentiation continue, and Gate's multi-asset trading capabilities for institutions are continuously improving

In the past week, inflationary pressures in the United States have eased somewhat, but weakening retail sales have raised concerns in the market about economic growth. Overall, U.S. stocks have maintained resilience, while the cryptocurrency market has been relatively weak. BTC ETF saw a weekly net outflow of approximately $385 million, and institutional allocations have cooled; BTC OI rose to about $12.3 billion, with funding rates remaining positive. Meanwhile, DEX weekly trading volume decreased by 5.2%, and the on-chain and DeFi markets have generally become more cautious.Against the backdrop of differentiated market risk appetite, Gate TradFi trading remains active, with weekly trading volume maintaining a high level of approximately $115 billion. Perp trading continues to grow, and the proportion of Korean stock trading has significantly rebounded. In terms of stocks, the latest exchange rankings from RootData show that Gate's stock spot and futures businesses have both entered the industry's top two, currently covering core markets such as U.S. stocks, Hong Kong stocks, and Korean stocks, further connecting traditional finance with digital assets.Based on the needs of professional investors, Gate has comprehensively upgraded its diverse service system covering TradFi, spot, and derivatives, providing a one-stop institutional-level trading infrastructure to assist global institutional investors in efficiently allocating various assets. In the face of market volatility and cross-market allocation needs, Gate continues to promote the construction of multi-market trading infrastructure. Its subsidiary, Gate CrossEx, has supported multiple mainstream venues, providing unified management of accounts, funds, positions, and trading across exchanges, significantly reducing multi-platform operating costs.

hot_img AWS officially launches Amazon Bedrock AgentCore payments, allowing AI agents to autonomously and securely complete payments

AWS announced that the Amazon Bedrock AgentCore payments service is officially fully available (GA). This service collaborates with Coinbase and Stripe, enabling AI agents to autonomously pay for paid APIs, MCP, and content services with just a few lines of code. AgentCore payments integrates Coinbase and Stripe Privy wallets, supporting small transaction payments in USDC stablecoin. Users can recharge the agent wallet and authorize the agent to spend using credit cards or USDC.The service supports the x402 protocol and MPP protocol, with a new "upto" payment scheme that allows agents to set spending limits instead of fixed prices, enabling dynamic billing based on actual reasoning usage. It includes built-in payment session limits (maximum spending per interaction and expiration time), which will be rejected if exceeded, and integrates AgentCore Observability to provide visual dashboards for transaction audit logs, success rates, and average transaction values.Related features have been integrated with CDNs such as Amazon CloudFront and Cloudflare, and clients such as Anchor Browser, SpreadX, and Travala are already using this service. AgentCore payments is now available in multiple regions, and developers can integrate it through the console, CLI, and open-source frameworks like LangGraph and OpenClaw. The launch of this service is a key step in the evolution of AI agents from "reasoning and action" to "autonomous transactions."
