Bitcoin hacks in 2023

$114M+ swept from Poloniex's Ethereum and Tron hot wallets after private keys were extracted from internal systems; Justin Sun pledged full reimbursement.

$200M drained from Mixin Network hot wallets after attackers compromised the cloud provider hosting Mixin's centralised database — an infrastructure wake-up.

Lazarus drained $54M from CoinEx hot wallets across Ethereum, Tron, BSC and seven other chains, reusing infrastructure from the prior week's Stake.com hit.

A private-key compromise drained $60M from AlphaPo's hot wallets across Tron, Bitcoin and Ethereum. The FBI attributed the payment-processor breach to Lazarus.

A Lazarus operation targeted Atomic Wallet's software, not individual seeds, draining $100M+ from roughly 5,500 users and bypassing self-custody guarantees.
