Qubic restarts blockchain, opens recovery claims after $1.4M hack
The network’s validators approved a recovery plan and opened claims until May 1, 2027.
Qubic, a Layer-1 blockchain, has restarted its network and initiated a recovery process following a wallet seed vulnerability incident that led to the unauthorized withdrawal of approximately $1.4 million worth of QU tokens from 1,404 accounts. According to the project's latest update, the network resumed processing ticks on October 19 at 8:00 pm, moving beyond tick 85,371,949, where it was previously halted.
Qubic's blockchain explorers indicate that network validators, referred to as Computors, have approved a recovery plan and launched a claims platform for those affected wallet holders. Affected users can verify their addresses and submit a claim via Qubic's reclaim platform, with the deadline for submissions set at May 1, 2027.
The network's halt on Sunday served the purpose of preventing further movement of the stolen funds, following the exploitation of a vulnerability that generated predictable wallet seeds in certain Apple devices and browsers. This weakness arose from an insecure random-number generator that could produce predictable seeds in the Qubic web wallet.
Qubic acknowledged the flaw and fixed it in the latest version of its web wallet, version 4.26.4 or later. The team advised users who created their wallets using the Qubic web wallet prior to version 4.26.4 to consider them insecure, even if their funds were not touched. They recommended updating to the latest web wallet version, creating a new wallet, and transferring their funds to it as soon as possible.
