According to Decrypt, Mozilla recently revealed that Anthropic's latest AI model, Claude Mythos, identified 271 security vulnerabilities during internal testing of the Firefox browser, and the related vulnerabilities have been fixed this week.In comparison, a previous version of the Anthropic model only found 22 security-sensitive vulnerabilities. Mozilla stated that all discovered vulnerabilities were within the scope of top human researchers' findings. Claude Mythos was officially released in March 2026 and is Anthropic's most powerful model in the fields of reasoning, coding, and cybersecurity, currently available for use by vetted partners such as Amazon, Apple, and Microsoft through the "Project Glasswing" initiative.

Letitia James has filed a lawsuit against Coinbase and Gemini, accusing them of providing "disguised gambling" services through their prediction market platforms, in violation of New York state law.Regulators believe that such trades based on event outcomes (such as sports and elections) essentially fall under gambling activities, particularly questioning the participation of users aged 18 to 21, while New York law sets the minimum age for sports betting at 21. The prosecution is seeking hefty fines and the recovery of profits, with claims of at least $2.2 billion against Coinbase and at least $1.2 billion against Gemini. The two companies have not officially responded, but Coinbase has indicated that prediction markets are regulated by the Commodity Futures Trading Commission, suggesting that their legality falls under federal jurisdiction.

Market news: Security personnel disclosed a critical vulnerability in Cosmos CometBFT 0-day, which may cause block synchronization phase stagnation affecting over $8 billion in assets.

At the "Crypto 2026: From Cryptocurrency to Smart Economy" themed forum held in Hong Kong, Gongye Feng, co-founder and CEO of Monera Digital, delivered a keynote speech titled "AI Empowered Private Banking for the Smart Economy."Feng pointed out that what disappeared after 2022 was not the demand for digital assets, but the market's confidence in the ways capital could enter. Monera Digital positions itself as an AI private bank for the smart economy, with the core not being to use AI as traders, but to act as an accelerator, compressing the research, testing, and iteration cycles from months to days.He emphasized that risk control must be institutionalized rather than personalized. Monera has built four lines of defense: source constraints on exposure and collateral, automated clearing and margin management, complete segregation of client assets, and eliminating maturity mismatches while maintaining liquidity buffers. Additionally, AI plays the role of a 24/7 digital CRO, achieving a leap from passive monitoring to proactive warning.In terms of service model, Monera does not operate as a pure technology platform, but insists on "anti-AI illusion," where AI is responsible for optimization and efficiency, while trust, responsibility, and continuity of relationships are still borne by humans. Feng believes that the prerequisite for crypto assets to truly become configurable assets is to translate complexity into clear, continuous, and trustworthy private banking services.

LayerZero posted on platform X that it is aware of the rsETH vulnerability incident and has been actively working with the KelpDAO team on handling and remediation since the incident occurred, while continuing to monitor the situation.LayerZero stated that, aside from the rsETH-related incident, other applications remain secure. Regarding the root cause of the incident, LayerZero is collaborating with SEAL_Org and others to investigate and has indicated that it will release a complete post-incident analysis report in conjunction with KelpDAO once all information is gathered.

According to Hyperbridge's official disclosure, the loss from the Token Gateway vulnerability incident has been revised from an initial estimate of $237,000 to approximately $2.5 million, with the increase mainly coming from losses in incentive pools on Ethereum, Base, BNB Chain, and Arbitrum.The attacker extracted about 245 ETH from the relevant contracts and then bypassed the MMR proof verification mechanism by forging cross-chain messages, minting 1 billion bridged DOT and selling them into a thinly traded market. Currently, some of the stolen funds have been traced on-chain to Binance, and Hyperbridge is collaborating with Binance's compliance team and law enforcement agencies for an investigation.Native DOT of Polkadot and products like Intent Gateway are unaffected, while the Token Gateway and the bridged DOT contracts on the four affected EVM chains remain suspended. The MMR verification logic patch is undergoing external audit, and the bridging functionality will be restored after the audit is completed.

According to CoinDesk, Blockstream CEO Adam Back stated at Paris Blockchain Week that Bitcoin developers should advance optional quantum-resistant upgrades as early as possible, even though practical quantum computers are still far from being realized.He pointed out that Taproot's flexible design can support the introduction of new quantum-resistant signature schemes without affecting existing users. Previously, Jameson Lopp and others proposed BIP - 361, which aims to gradually phase out addresses vulnerable to quantum attacks within 5 years and freeze Bitcoin that has not completed migration. Adam Back believes that the Bitcoin community can quickly coordinate responses in emergencies without the need for pre-established freezing arrangements.

The UK asset management firm Legal & General has put its managed liquidity funds, exceeding £50 billion, on-chain through the tokenized distribution network launched by Calastone.The firm is now offering money market funds in tokenized share form on this network, supporting USD, EUR, and GBP, covering issuance, trading, and same-day settlement. Investors can purchase, hold, and transfer the related tokenized shares within a permissioned, regulated network. The relevant funds will be deployed on Ethereum and compatible blockchains, with plans to expand to more networks in the future.

According to CriptoNoticias, an independent security researcher disclosed a prompt injection vulnerability in Coinbase AgentKit, allowing attackers to induce the AI agent to execute unauthorized token transfers through malicious commands, without the need for human confirmation.The vulnerability has been validated through actual transactions on the Base Sepolia test network. Additionally, the researcher pointed out that the vulnerability also exposes the infinite approval process for ERC-20 tokens, as well as access to remote servers within the same execution context of the agent, extending the risk beyond just wallet depletion; however, the report did not detail which specific infrastructures might be affected.The vulnerability was submitted to the Coinbase bug bounty program in February and was officially validated, ultimately classified as medium severity and a bounty of $2,000 was paid. However, the researcher emphasized that the actual impact of the vulnerability is far greater than the official rating.

According to market news, Cypherpunk Jameson Lopp and several experts in the field of Bitcoin quantum security have proposed Bitcoin Improvement Proposal BIP-361, which suggests freezing quantum-vulnerable addresses, including Satoshi Nakamoto's reserves, to prevent future quantum computers from stealing approximately 1.7 million Bitcoins.The proposal is to be implemented in three phases: first, prohibiting transfers to legacy addresses; second, invalidating legacy signatures and freezing untransferred assets after five years; and finally, allowing some users to recover frozen funds through a zero-knowledge proof mechanism. This proposal aims to promote the migration of the entire network to quantum-resistant addresses, but it has faced opposition from some community members who believe it contradicts the decentralized ethos of Bitcoin and has a predatory nature.

The security agency Innora released a report stating that the financial protocol Saturn on Ethereum has two serious vulnerabilities. These include:Withdrawal freeze vulnerability: Under normal business operations, all user funds could be locked, with a minimum of 30 days and, in extreme cases, indefinitely frozen. No hacker is needed; the protocol can trigger this itself.Privileged addresses in the protocol can legally intercept up to 33.33% of the funds per operation. According to current data, a single operation can intercept up to approximately $157,000, with a theoretical total risk of up to $4.26 million.Innora stated that over 90% of Saturn's assets are managed by privileged addresses, and users are completely reliant on trust. As of the report's release, this vulnerability has not yet been fixed.
