The Central Board of Secondary Education (CBSE) has filed a complaint with the Delhi Police regarding a series of coordinated cyberattacks targeting its post-result services portal.
The portal, launched on June 2 for Class 12 students, was subjected to repeated and coordinated cyber attacks over the past three days, involving large volumes of malicious traffic from multiple IP addresses.
Although no data breach or unauthorized access has been detected, the apparent objective of the attackers was to destabilize the platform, deny access to legitimate users, and attempt unauthorized extraction of information.
The board re-launched the re-evaluation portal on Tuesday and reported a major denial-of-service (DoS) attack that flooded the network with 1.5 million hits within a two-minute window.
As of June 4, a total of 70,433 successful applications have been received through the CBSE post-result grievance redressal process, including 7,314 applications for Verification of Marks and 63,119 applications for re-evaluation.
The board said the attacks were successfully mitigated through continuous 24×7 monitoring and response mechanisms, with support from cybersecurity teams of IIT Kanpur, IIT Madras, and other central government agencies.
