CertiK links Lazarus Group to a series of major 2023 Web3 breaches affecting Atomic Wallet, Alphapo, CoinsPaid, Stake.com, and CoinEx, with at least $291.3 million in recorded losses across the five incidents. The analysis cites on-chain correlations between the breaches, including shared or connected wallet flows across Ethereum and Tron infrastructure, as evidence tying the activity together. The body also describes North Korean-linked supply-chain and identity-infrastructure intrusions affecting 3CX and JumpCloud, with the JumpCloud breach traced to the Lazarus subgroup Labyrinth Chollima and assessed as potentially enabling downstream compromise of Web3 firms. CoinsPaid’s postmortem is used as a concrete example of Lazarus-style social engineering, where fake LinkedIn recruiters lured employees into installing a malicious JumpCloud Agent under the guise of a technical task. The pattern matters for Web3 defenders because the reported compromises focus less on exploiting smart contracts directly and more on stealing private keys or credentials through Web2 dependencies and personnel targeting.
