Slow Fog's Yuxian stated on platform X that the Bitget theft incident has a wide spread, involves a huge amount of money, and the related funds were quickly linked to North Korean hackers. Institutions such as Circle and Tether have promptly assisted in freezing the related funds, with Circle freezing the USDC held by the hackers.Regarding THORChain, Yuxian pointed out that when THORChain previously experienced a theft incident, it also quickly intervened in its so-called "decentralized" platform; however, in response to this major security incident in the industry, it claimed "decentralization and non-interference" and compared itself to Bitcoin and Ethereum, while continuing to earn fees from the hackers' large cross-chain transactions.He stated that decentralization should not just be a slogan; after a major security incident occurs, the key is to distinguish which issues need to be collectively addressed by the industry. He also believes that platforms like THORChain should not be easily compared to Bitcoin and Ethereum, as there are significant differences in the degree of decentralization and mechanisms of different systems.

On September 23, Google announced that any user with a Google account can generate 1080p HD videos for free in its browser-based video editor Google Vids, accessible at vids.new. This feature is based on the Gemini Omni 1.1 Flash model and can transform text prompts, photos, audio, or existing clips into new videos. Previously, such generative capabilities mostly required a paid subscription to use.Google has also added several editing controls that previously required paid tools: scene extension can lengthen clips while maintaining consistency in lighting, characters, and scenes; users can set precise clip durations to align with scripts or voiceovers; and old AI clips with lower resolutions can be upgraded to 1080p without needing to regenerate. Each video segment generated by this tool embeds Google DeepMind's SynthID invisible watermark, which is not visible to the naked eye but can be read by machines. Users can check whether a segment was generated by AI using the SynthID Detector.The free quota varies by account type: personal Google accounts receive a standard quota, paid AI packages can unlock more, and Workspace Business and Enterprise subscribers receive a larger generation pool and team management controls. Gemini Omni will be launched as a paid feature for Google AI Plus, Pro, and Ultra subscribers in May 2026, with free access previously limited to YouTube Shorts and YouTube Create.

Bitget CEO Gracy Chen stated on the X platform that the Bitget bounty recovery program has been launched: a 5% reward for facilitating the freezing of the attackers' funds, and an additional 5% reward for successfully recovering the funds.

Bitget stated that the attack resulted in losses of about $351.6 million, with the attackers breaching the wallet service backend system, forging transfer information, and triggering the authorization signature process, ruling out private key leakage.

The Google Product Security Team has disclosed an internal AI agent called PageBreak, used to test the security of its first-party web applications. This agent is built on Google's Gemini model and began a pilot program in November 2025, transitioning to a formal project in January 2026, with the goal of autonomously scaling vulnerability discovery and reducing manual input.Unlike common AI scanning tools, PageBreak hands over hypotheses to specialized validators after discovering suspicious defects, attempting actual exploitation in a real-time running copy of the application, and only reports once confirmed exploitable, with a false positive rate close to zero. Google claims that PageBreak has identified over 500 XSS vulnerabilities in its first-party web applications, which can be used to hijack login sessions, steal data, or impersonate users.Google stated that the security team has been overwhelmed in recent years by a large number of AI-generated vulnerability reports that appear reasonable but are not valid, making it a major challenge to distinguish real defects from hallucinations. When testing applications built using the next-generation high-assurance framework, PageBreak found only two vulnerabilities. The next step for Google is to integrate PageBreak with the automated remediation agent CodeMender, providing confirmed vulnerabilities with accompanying fixes.

The Circle Foundation announced two grants to the United Nations Development Programme (UNDP) and the World Food Programme (WFP) to explore the application of digital payments and digital financial infrastructure in humanitarian aid and development projects.The Circle Foundation stated that the relevant programs will study how to utilize digital payments and regulated payment-type stablecoins to disburse funds to aid recipients more quickly, transparently, and at a lower cost.For the UNDP, the grant will be used to establish and operate a "Digital Asset Innovation Pool," helping country offices expand previous digital payment pilot projects conducted in Syria, Haiti, Guatemala, and Gambia from single projects to regular project execution, and provide support such as regulation, operations, and beneficiary protection; this mechanism will not replace traditional banking channels but will serve as a complementary option outside the existing payment system.For the WFP, the grant will support the establishment of governance, risk management, funding, reconciliation systems, and compliance tools necessary for stablecoin payments, and integrate local fintech and mobile payment services. Over the next three years, the WFP plans to test 2 to 3 payment channels connecting its payment system with local financial service providers and markets to assess the performance of stablecoin payments in terms of efficiency, transparency, and resilience.
