Tin tức từ ChainCatcher, giao thức lợi nhuận đa chuỗi BounceBit đã phát hành thông báo sự cố an ninh cho biết, mạng lưới blockchain của họ đã gặp phải một cuộc tấn công lỗ hổng cấp độ giao thức từ 21:02 UTC ngày 19 tháng 8 đến 01:54 UTC ngày 20 tháng 8. Kẻ tấn công đã lợi dụng lỗ hổng ủy quyền trong kiến trúc nền tảng Evmos để chuyển nhượng 9 tài khoản mainnet của BB token mà không có sự cho phép của chủ sở hữu tài khoản. Theo thông báo, kẻ tấn công đã chuyển nhượng tổng cộng khoảng 286.5 triệu BB thông qua 14 giao dịch.Phạm vi ảnh hưởng của sự cố chỉ giới hạn trong chính BounceBit Chain, không liên quan đến việc rò rỉ khóa riêng, giả mạo chữ ký, ví, thiết bị phần cứng hoặc vấn đề an ninh tài khoản sàn giao dịch. Các sản phẩm BounceBit CeDeFi Strategy, Promo Vaults, Prime và RWA đều không bị ảnh hưởng.BounceBit cho biết, lỗ hổng xuất phát từ thiếu sót trong xác thực ủy quyền của mô-đun gốc giao thức trong kiến trúc Evmos. Kẻ tấn công đã vượt qua kiểm tra an ninh mà lẽ ra phải xác minh mối quan hệ ủy quyền giữa tài khoản nguồn vốn khi gọi mô-đun liên quan thông qua hợp đồng thông minh, cho phép họ chỉ định bất kỳ tài khoản nào làm nguồn vốn.Sau sự cố, BounceBit Chain đã dừng việc tạo khối tại chiều cao khối 20,702,857, sau đó đội ngũ quyết định không nâng cấp chuỗi mà sẽ đóng cửa vĩnh viễn BounceBit Chain, và phát hành lại BB dưới dạng token BEP-20 dựa trên BNB Chain. BounceBit cho biết, nguồn cung BB mới sẽ dựa trên snapshot trên chuỗi trước giao dịch chuyển nhượng bất thường đầu tiên (chiều cao khối 20,697,260), 286,543,148 BB mà kẻ tấn công đã chuyển nhượng sẽ không được tính vào số dư token mới.Người dùng không cần phải nộp đơn hoặc di chuyển ví, chính thức sẽ tự động phân phối BB mới đến địa chỉ BNB Chain tương ứng. Đối với BB đang được staking, BounceBit cho biết sẽ khôi phục cùng thời điểm snapshot, người nắm giữ token không cần thực hiện thao tác hủy liên kết hoặc rút tiền. Hiện tại, BounceBit đã gửi yêu cầu đóng băng và hỗ trợ đến các sàn giao dịch liên quan, và nhắc nhở người dùng cảnh giác với lừa đảo, không nhấp vào bất kỳ liên kết chuyển nhượng hoặc nhận BB nào chưa được xác nhận bởi chính thức. Đội ngũ cho biết, sẽ công bố địa chỉ hợp đồng BEP-20 BB mới và tiến trình phát hành lại trong thời gian tới.

ChainCatcher news, according to The Block, the Interchain Foundation (ICF) has funded the open-source Evmos (EVMOS -32.90%), which is the native EVM framework of its multi-chain ecosystem that includes over 200 application chains.The foundation stated that this framework was previously developed under the Evmos project and will now be maintained as "Cosmos EVM" within the official cross-chain software stack, including the Cosmos SDK, which means the Cosmos ecosystem now has a standardized Ethereum Virtual Machine (EVM) version.This development enables the Cosmos blockchain to integrate Cosmos EVM for full EVM compatibility, including support for JSON-RPC and Ethereum wallet compatibility through lightweight EVM configurations for native ERC-20 tokens. The integration enhances cross-chain interoperability between the broader EVM ecosystem and Cosmos through the Inter-Blockchain Communication (IBC) protocol.As part of this transition, Evmos co-founder Federico Kunze Küllmer will no longer serve as a core contributor to Evmos, while continuing to advise the ICF on the interoperability and modular architecture of Cosmos EVM, Evmos noted. Kunze Küllmer's company, Altiplanic, is a core contributor to the Evmos codebase and will no longer participate in the project.

ChainCatcher news, according to Cointelegraph, a Web3 security researcher earned a $150,000 bounty by reading the Cosmos network documentation and discovering a serious vulnerability that could cause the Evmos blockchain and all decentralized applications (DApps) built on it to stop functioning.In a blog post published on October 28, the security researcher "jayjonah.eth" explained the concept of "module accounts" encountered in the Cosmos documentation, stating: "If these addresses (module accounts) receive funds outside the expected rules of the state machine, invariants may be violated, potentially leading to a network halt." Based on the Cosmos documentation, the Evmos blockchain was subjected to crash testing, where the security researcher attempted to send funds to the module accounts in a testing environment to test this theory, reporting: "At this point, no blocks are being generated anymore, and the blockchain has completely stopped. This would compromise the Evmos blockchain and all DApps built on it." He revealed that the Evmos team had already fixed the vulnerability before the information was made public.

ChainCatcher news, according to official sources, Ripple has collaborated with Evmos to develop the XRP Ledger EVM sidechain, which will be built using evmOS technology. evmOS is a modular and customizable technology stack provided by Evmos, leveraging Cosmos SDK, IBC, and CometBFT to bring EVM compatibility to Web3 enterprises.

ChainCatcher news, the Cosmos ecosystem EVM-compatible chain Evmos has officially launched the dApp store Evmos dApp Store on social media platforms.

ChainCatcher news, according to The Block, Evmos developer Altiplanic is developing a mechanism that allows Cosmos tokens to be used as ERC-20 tokens on the Evmos blockchain. The planned release will provide Evmos developers with a unified token model applicable to both native tokens and ERC-20 tokens.Essentially, this integration will enable Cosmos tokens (which are not compatible with the ERC-20 standard) to be used directly in dapps on the Evmos EVM. The mainnet version of the mechanism is expected to be released by the end of this year.

ChainCatcher message, the Cosmos ecosystem's EVM-compatible chain Evmos plans to stop supporting Cosmos transactions and instead focus on Ethereum-based transactions. The Evmos core network will only support Ethereum-based wallets and tools. The transition to a single transaction format is expected to simplify the development workflow and improve the efficiency of Ethereum wallets on the network. Evmos announced a phased cessation of Cosmos transactions, aiming for full completion by the third quarter of 2024.In addition, Evmos will maintain core functionalities of Cosmos, such as staking and token transfers via EVM extensions, ensuring users and developers have access to these features.
