Stake disclosed a hot-wallet breach on 4 September 2023 after unauthorized withdrawals from its Ethereum, Polygon, and Binance Smart Chain wallets. Merkle Science attributes the incident to a private-key leak and says the stolen assets included ETH, stablecoins, and native tokens moved through associated addresses and decentralized exchanges. Its flow analysis found the attacker split funds across the three EVM chains, swapped assets into ETH, BNB, and MATIC, and sent them onward to newly created addresses. The excerpt does not attribute the hack to Lazarus or another DPRK actor, so the summary should be treated as cryptocurrency theft context rather than DPRK attribution.
