Qubic Wallets Drained: Seed Bug Suspected
Qubic, a cryptocurrency protocol, confirmed that 1,404 wallets were drained on October 17-18, resulting in about 2.94 trillion QU. The network attributes the vulnerability to weak seeds, which were used on iPhones and iPads before October 18, Macs on Safari before that date, or the Qubic iOS app before July 2025. The protocol halted the chain at tick 85,371,949 to prevent the stolen funds from moving further. 87.1% of the drained funds are still on the network, while 12.9% were sent to MEXC. Exchanges suspended QUBIC deposits and withdrawals. The team has fixed the seed bug in version 4.26.4, but victims are advised to file a police report with their wallet ID, amount, and explorer link. The hacker is suspected to be a researcher, and the Qubic team is identifying affected identities for a community poll on Discord.
