Qubic Pushes Back on Hack Claims: Weak Wallet Seeds Were to Blame

Qubic has confirmed that an attacker drained 1,404 wallets, stealing around 2.94 trillion QU during a security incident between October 17 and 18. The network said the problem came from weak wallet seed generation, not a flaw in the Qubic protocol itself. Weak Wallet Seeds According to the update, some wallet seeds were created with insufficient randomness, making them easier to compromise. The affected seeds were generated on iPhones and iPads using any browser before October 18, on Macs using Safari before that date, or through the Qubic iOS app before July 2025. Qubic’s validators, known as Computors, coordinated a halt at tick 85,371,949 to prevent further movement of the stolen funds. With transactions paused, 87.1% of the drained funds remain on the network and frozen.
