Wu said he learned that Qubic, a Layer 1 network based on a proof-of-useful-work mechanism, has suffered a security incident affecting its GitHub organization. A compromised account was used to access code repositories and extract confidential information, and remediation is currently underway. Qubic advises Network Guardian to immediately replace its seed. Users who unlocked the Web Wallet between 11:00 and 18:00 Beijing time on July 13 should transfer their assets to a new identity, and Qubic reminds developers not to pull or deploy code from the Qubic code repository before the audit is completed. Qubic says that users who did not unlock their wallet during the above time window are not directly affected by this attack.
