Useful PoW-based Qubic has also fallen victim to a security incident—account intrusion, confidential data leakage, and an emergency seed change. The impact isn’t small; developers, don’t touch the repository for now.

Wu Says learned that Layer 1 network Qubic, based on a Proof of Useful Work mechanism, has experienced a security incident involving its GitHub organization: a compromised account was used to access the code repository and extract confidential information, and remediation is currently underway. Qubic advises Network Guardian to immediately rotate its seed. Users who unlocked their Web Wallet between 11:00 and 18:00 Beijing time on July 13 should transfer assets to a new identity, and it also reminds developers not to pull or deploy code from Qubic’s code repository before the audit is completed. Qubic says users who did not unlock their wallets in the above period are not directly affected by this attack.
