    F5 breached by nation-state actor: BIG-IP source code and undisclosed bugs stolen

    F5 disclosed that a sophisticated nation-state actor had long-term access to its BIG-IP development and engineering systems and stole parts of the BIG-IP source code, information on undisclosed vulnerabilities and some customer configuration data. CISA issued Emergency Directive 26-01 ordering agencies to inventory and patch F5 gear. Researchers linked it to China-nexus UNC5221 and BRICKSTORM.
