A recent hack targeting Qubic wallets resulted in the theft of 2.94 trillion QU, but swift action by the network and exchanges mitigated the damage. This is an original Token Times brief based on reporting by Cointribune, with live market data added, as of Mon, 02 Nov 2026 04:30:01 UTC.
The incident highlights both the vulnerabilities in wallet security and the effectiveness of coordinated response mechanisms in limiting crypto theft impacts.
- Attackers stole 2.94 trillion QU from 1,404 wallets on October 17-18.
- Network stopped 87.1% of stolen funds; exchange froze remaining assets.
- Recovery efforts ongoing with 293 billion QU already returned to the chain.
On the night of October 17 to 18, an attacker exploited a vulnerability to steal 2.94 trillion QU from 1,404 Qubic wallets. The breach was not due to a protocol flaw but rather an issue with seed generation on certain Apple devices, which also affects intact wallets.
In response, the Qubic network's Computors acted quickly to halt operations, freezing 87.1% of the stolen funds. The exchange MEXC also played a crucial role by blocking the account that received the remaining funds within an hour of the attack.
Twelve days after the incident, the network has resumed operations. Of the frozen funds, 293 billion QU have been returned to the chain, and reimbursements for verified owners are underway.
The incident underscores the importance of robust security measures and rapid response protocols in the cryptocurrency space. While the network's actions prevented a more significant loss, the vulnerability affecting Apple device seed generation remains a concern.
The broader crypto market remains relatively stable, with 
Bitcoin showing a modest 24-hour gain of 0.97% and the overall market cap at $2.7 trillion. The Fear & Greed index stands at 37, indicating a 'Fear' sentiment among investors.
