Layer 1 network Qubic said in a post that between 23:42 UTC on October 17 and 01:26 UTC on October 18, an attacker exploited insufficient randomness in certain wallet seeds to compromise 1,404 wallets and drain approximately 2.94 trillion QU. The vulnerability originated in the seed-generation mechanism, not the Qubic protocol itself.
Qubic halted network transactions at tick 85,371,949. Some 87.1% of the stolen funds remain on the network and are frozen, while the remaining 12.9% was transferred to MEXC, where the receiving account has also been frozen. Other exchanges have suspended QUBIC deposits and withdrawals. Qubic fixed the seed-generation issue in version 4.26.4, and any further resolution will be determined by the Computor quorum under the network’s rules.
