Web3 Platform Mixin Network Hit by $200m Crypto Hack

AI-summarised brief · reviewed before publication

Hong Kong‑based decentralized finance project Mixin Network disclosed a cyber‑attack that compromised its cloud service provider’s database on September 23, 2023, resulting in the loss of roughly $200 million in cryptocurrency. The breach forced the platform to suspend deposit and withdrawal services while transfers remained operational, and Mixin enlisted Google and blockchain security firm SlowMist to investigate. Founder Feng Xiaodon addressed users in a live Mandarin briefing on September 25, outlining remediation steps, and the project later reported a $30 million drop in total value locked, according to DeFi Llama. Launched in 2017, Mixin’s XIN token supports cross‑chain transactions for about 10,000 DApps. The incident ranks as the fifth‑largest crypto hack outside exchanges, trailing incidents such as Ronin, Poly Network, BNB Bridge and Wormhole.

💡 Why It Matters

  • · The hack exposes the vulnerability of “decentralized” platforms that still depend on centralized cloud infrastructure, challenging the core security premise of Web3.
