According to the Board, the attacks involved large volumes of malicious traffic originating from multiple IP addresses within and outside the country. The apparent objective was to destabilize the platform, deny access to legitimate users and attempt unauthorized extraction of information.
CBSE said it has approached the IFSO Unit for a detailed investigation and appropriate legal action against those responsible. The Board emphasized that its systems and databases remain secure and uncompromised, with no data breach or unauthorized access detected.
The attacks were successfully mitigated through continuous 24×7 monitoring and response mechanisms, with support from cybersecurity teams of IIT Kanpur, IIT Madras, Digital India Corporation, the Indian Cyber Crime Coordination Center (I4C), CERT-In and other Central Government agencies.
