Qubic Wallet Exploit Leads to $1.3 Million Loss
An exploit in Qubic wallet seed generation resulted in a significant loss of funds. The issue affected multiple wallets due to insufficient randomness in seed creation.
An attacker exploited a vulnerability in the seed generation process of Qubic wallets, impacting wallets created in specific environments including browsers on iPhone/iPad, Safari on Mac before October 18, 2026, and the Qubic iOS app before July 2025. This exploit allowed the attacker to drain approximately 2.94 trillion QU, equating to around $1.3 million, from a total of 1,404 wallets. It is important to note that the issue was related to seed generation and not the Qubic protocol itself.
In response to the incident, the Qubic network was halted, and most of the affected funds were frozen to prevent further losses. The development team addressed the vulnerability by fixing the seed generation process in version 4.26.4 of the software. This action was crucial in mitigating the impact of the exploit and securing the remaining funds.
The incident highlights the importance of robust seed generation methods in cryptocurrency wallets. While the specific blockchain is not stated, the scale of the loss indicates a significant impact on users who relied on the affected wallet versions.
