Qubic network relaunches after exploit; recovery claims now open but require separate ownership proof due to weak seed vulnerability.
Security & Exploits ·
Qubic announced its network resumption on October 20, 2026, following quorum approval of a recovery plan, with a reclaim platform now open for affected users to retrieve assets held in protected escrow during the network halt. The recovery process requires claimants to submit a signed message from their compromised identity alongside separate ownership evidence, because weak seeds used in wallet generation allow an attacker to produce valid signatures identical to those of legitimate owners—making cryptographic proof of the transaction alone insufficient for authorization.
The platform accepts exchange withdrawal receipts showing transfers to the affected address as the strongest evidence category, followed by OTC confirmations, pre-incident funding trails from addresses the claimant controls, or signed messages from unaffected addresses that previously funded the compromised wallet. The Qubic team instructs all users of the web wallet prior to version 4.26.4 to cease using those wallets immediately, create fresh identities in updated versions, and route recovered funds to newly generated addresses rather than back to compromised identities. Recovered assets do not return automatically; the Computor quorum retains final decision authority over claim determinations based on the ownership evidence submitted.
The claim portal's introductory text still describes the network as halted, creating ambiguity about its current operational state despite the resumption announcement. No figures have been disclosed for the initial funds returned to verified owners, and the timeline for processing remaining claims remains unstated.
