CBSE says revaluation portal faced 1.5 million cyberattack hits in two minutes

The Central Board of Secondary Education (CBSE) on June 2 said its Class 12 revaluation portal was targeted by a series of cyberattacks, receiving around 1.5 million hits within two minutes after the service went live. The board said the attacks were successfully blocked and no student data was compromised.

In a statement, CBSE said "malicious actors" attempted to disrupt services while thousands of students were accessing the portal for verification of marks, obtaining photocopies of answer books and revaluation-related services. The board said the attack generated 1.5 million hits within two minutes.

CBSE further said it detected more than one lakh attempts to gain unauthorised access to files on the portal. According to the board, its security systems blocked these attempts and prevented any breach of student records.

The board said the portal continued to function despite the attacks and that more than 16,000 students were able to submit applications through the system.

The latest incident comes days after CBSE reported a separate malicious attack on its revaluation portal's payment system. According to reports citing government sources, the earlier breach affected payment processing and enabled around 50 students to gain unauthorised access, resulting in abnormal fee displays on the portal.

Following that incident, CBSE postponed the next phase of the revaluation process and later reopened the portal on June 1 after implementing additional safeguards.

The board said vulnerabilities identified in the service provider's system had been contained and that steps were being taken to ensure a transparent and glitch-free process.

The revaluation portal is being used by Class 12 students seeking verification of marks, photocopies of answer books and re-evaluation of answers following the declaration of board examination results.
