Qubic halts mainnet after $1.3M stolen from 1,404 wallets via weak Apple device seeds

Qubic, a decentralized AI network, paused its mainnet after an attacker drained about $1.3 million worth of QU tokens from 1,404 wallets. The breach exploited weak wallet seeds generated on legacy Apple devices and early iOS apps, not a bug in Qubic's code. Most stolen tokens remain frozen on-chain, while some were frozen by exchange MEXC. Qubic released a patch to fix the vulnerability and secured other exposed funds. The network’s staking feature was unaffected. The community awaits decisions on victim compensation and mainnet restart timing.
