Qubic Attack Drains 2.94 Trillion QU From 1,404 Wallets

The Qubic attack drained approximately 2.94 trillion QU tokens worth around $1.3 million from 1,404 wallets between October 17 and 18, 2026. The Layer 1 network halted transactions after identifying the incident, while 87.1% of the stolen funds remained frozen on-chain. The remaining tokens were transferred to MEXC, where the receiving account was also frozen. The incident resulted from weaknesses in wallet seed generation rather than a direct exploit of the Qubic attack blockchain protocol. The attacker exploited insufficient randomness in seeds generated by certain Apple devices and browsers.
