Cơ sở hạ tầng giao dịch phi tập trung 0x đã công bố rằng, trong năm nay, họ đã định tuyến 81,92 triệu giao dịch, với tổng giá trị giao dịch đạt 42,67 tỷ USD, khoảng 70% liên quan đến thanh khoản của Uniswap. 0x cho biết, gần đây có sự gia tăng các hooks độc hại của Uniswap v4, loại hooks này đưa ra một mức giá trong yêu cầu báo giá, nhưng khi thanh toán lại đưa ra một mức giá khác, qua đó lừa đảo các aggregator, ví và ứng dụng giao dịch để thu lợi từ người dùng.Sau khi phân tích 84.163 hooks trên 6 chuỗi, 0x cho biết chỉ có 19,4% là an toàn, 54,2% là độc hại, và 26,4% có thể là độc hại. Các giao dịch được định tuyến qua các hooks độc hại v4 có thể nhận được số tiền thực tế ít hơn 50% so với mức giá báo giá. Bài viết đưa ra ví dụ về các hooks của pool ETH/NVDAc trên chuỗi Base đã thu được khoảng 143.000 USD, và các hooks của pool USDT/WBNB trên chuỗi BNB đã thu được khoảng 18.600 USD.0x cho biết, các bên định tuyến cần đảm bảo rằng số tiền báo giá của pool phải phù hợp với hành vi thực thi, các ứng dụng cần có khả năng nhanh chóng loại bỏ các định tuyến nghi ngờ, và người dùng nên biết rằng chỉ khi định tuyến an toàn thì mức giá tối ưu mới có giá trị. 0x đã thực hiện các biện pháp như kiểm tra và đánh giá pool để tránh các pool như vậy xuất hiện trong định tuyến.

According to research by OpenSourceMalware, the North Korean hacker group Lazarus has adopted new techniques in malicious activities targeting developers, such as "infectious interviews" and "TaskJacker," hiding the second-stage loader in the pre-commit scripts of Git Hooks. "Infectious interviews" is a series of attack activities where the organization lures developers into cloning malicious code repositories by faking recruitment processes in the cryptocurrency/DeFi field, ultimately stealing crypto assets and credentials.Researchers recommend that developers who are asked to clone code repositories as part of the interview process should be wary of such risks and preferably run in an isolated environment to avoid mounting personal browser configurations, SSH keys, and cryptocurrency wallets.

Hiro Team recently announced the Beta testing of Chainhooks 2.0. Chainhooks is the development infrastructure for the Stacks and Bitcoin ecosystems.Hiro stated that Chainhooks 2.0 has been completely restructured based on the experiences from version V1, aiming to address issues such as unreliable infrastructure, high maintenance costs, and difficulty in scaling found in the old version.

This Beta version currently only supports Stacks chain filtering, but the future roadmap plans to support Bitcoin filtering and will introduce a command-line tool (CLI). Hiro emphasizes that with the adoption and increasing transaction volume of sBTC, reliable tools like Chainhooks are crucial for the development of the ecosystem.
