According to Cointelegraph, the Qubic blockchain network has been frozen following an incident in which an attacker exploited weak seed phrases associated with approximately 1,400 user wallets. The network’s operators confirmed the freeze in response to the unauthorized access and withdrawal of funds from these accounts.
Qubic indicated that roughly 87.1 percent of the stolen amount remains onchain within the affected wallets, while the remainder was located at the crypto exchange MEXC, where it has been frozen pending further action. Validators on the Qubic network are currently preparing to vote on a formal recovery plan.
The use of weak seed phrases—described by Qubic as improperly generated or reused keys—enabled the attacker to access multiple wallets without additional authentication. No technical details about the method of key extraction or propagation were provided. The freeze affects only the operational state of the chain for administrative and security purposes; no change is described regarding wallet ownership status aside from what is publicly visible onchain.
Qubic has not announced a timeline for restoration of normal operations. The vote among validators on the recovery plan is expected to occur after internal review, but no date or voting threshold was specified. Users are advised to follow official Qubic channels for updates.
