Qubic web wallet

RSS

The Qubic web wallet suffered a seed‑generation flaw that allowed attackers to drain 2.94 trillion Qubit from over 1,400 wallets. Seeds were generated by Math.random() when using iPhone/iPad browsers, Safari on a Mac until Oct 18 2026, or the Qubic iOS app before July 2025. Qubic halted the network at tick 85,371,949. 87.1 % of the 1.4 million‑USD theft stays on‑chain; 12.9 % was transferred to MEXC, whose account was frozen within an hour. Qubic fixed the vulnerability in web‑wallet v4.26.4 by replacing Math.random() with crypto.getRandomValues(). The core team is identifying affected wallets and preparing a recovery plan voted by Computors.
