The CBSE revaluation portal’s payment system was hit by a malicious attack, allowing around 50 students unauthorised access, according to sources. The glitch, linked to an HDFC payment gateway, caused fee amounts to fluctuate wildly from ₹1 to nearly ₹67,000–₹68,000. IIT Madras, IIT Kanpur and DICT are reviewing the system, while PSU banks and AWS integration are being used to strengthen security.

New Delhi: The CBSE revaluation portal's payment system was hit by a "malicious attack", with around 50 students gaining unauthorised access, government sources said on Friday.

"There were some unauthorised attack on the portal. The payment gateway was with respect to HDFC… about 50-odd children had got in," a source said.

According to the sources, the issue led to abnormal fee displays on the portal, where the payable amount in some cases fluctuated from around Rs 1 to nearly Rs 67,000-68,000.

"I think out of fun or out of mala fide intention, I think that one rupee was shown and then Rs 67-68,000. So, there were about 50 children in whose case the amount had changed," the source said.
