🔥We placed 7th in the first @xyz_remedy CTF of 2025! Competing against 1,904 teams for a prize pool of $52,000+, the competition was fierce.
Kudos to our teammates, especially those who dedicated their time despite the busy period leading up to Chinese New Year. 🙌
Thanks to @hexens for hosting such a great CTF – the experience was amazing! 🫡
We almost grabbed a flag in the final minute but were dramatically hit by a instance timeout. So thrilling – this is what CTF is all about. See you in the next CTF! 💪

DeFiHackLabs 是一個非營利、社區驅動的區塊鏈安全研究社區，致力於提升 Web3 安全，透過知識分享、漏洞研究、參與 CTF、審計比賽來培養區塊鏈安全專業人才與提升區塊鏈生態安全。
DeFiHackLabs 社區於 2022年10月創立，當時只有不到10位白帽，目前社區超過 300 位白帽來自世界各地，50% 來自亞洲.
社群宗旨
1.推動區塊鏈安全發展：分析 EVM、Non-EVM、DeFi、Layer2、跨鏈橋等 Web3 領域的安全漏洞，研究攻防技術涵蓋智慧合約安全、鏈上監控分析、用戶資產安全、反洗錢、CTF、緊急事件處理及被盜資金救援等等。
2.培養安全人才：舉辦培訓營、CTF 挑戰賽、工作坊、實體聚會、線上讀書會，讓更多開發者、白帽駭客、合約審計師學習與交流。
3.提升社群影響力：透過技術研究、發佈漏洞分析報告、貢獻開源工具、參與國際競賽，讓 DeFiHackLabs 成為 Web3 安全領域的重要社群之一。
社群活動
1.培訓營（BootCamp）：例如以太坊安全開發訓練營，提升智能合約審計與區塊鏈安全知識。
競賽（CTF / Security Challenge）：社群成員積極參與 2.Web3 安全競賽，並在國際比賽中屢獲佳績。
3.技術分享（Meetup & Workshop）：邀請區塊鏈安全專家分享最新攻防技術，促進技術交流。
4.技術研究（Research & Writeups）：發佈漏洞分析報告、Web3 安全事件分析、審計經驗分享等。
成就與影響
1.2024 年 11 月：團隊獲得 第一屆 Scan Digital Asset 競賽 全球冠軍（490 支隊伍參賽）。
2.2025 年 1 月：團隊參與 Remedy CTF 全球第 7 名（1,904 支隊伍）。
3.與多個優秀伙伴如 SlowMist、Fuzzland、BlockSec、BitsLab、ChainLight、Security Alliance 等合作，推廣 Web3 安全知識。
4.舉辦以太坊安全開發 BootCamp，由以太坊 ESP 支持，培養 Web3 安全人才。
5.舉辦白帽養成特訓: 第一期: 合約審計、攻擊重現POC開發、金流分析。
社群理念
DeFiHackLabs 希望打造一個開放的區塊鏈安全學習環境，讓更多對 Web3 安全有熱忱的人共同成長，對抗駭客與詐騙，維護生態系統的安全。
如果你對智能合約安全、區塊鏈攻防技術、DeFi 安全漏洞分析、金流分析有興趣，歡迎加入 DeFiHackLabs，一起學習和貢獻！🚀
