In the wake of the recent Class 12 board results, thousands of students have been navigating the post-result procedures. However, the Central Board of Secondary Education (CBSE) revaluation portal recently faced an unexpected hurdle: a malicious cyber attack that disrupted the payment process for students seeking answer sheet verifications.

At Compare School, we know that the post-result period is already a highly stressful time for students and parents. To help clear up the confusion, we have broken down exactly what happened, how CBSE is fixing it, and what you need to do next.

What Exactly Happened?

Shortly after the CBSE post-result and revaluation portal went live on May 19, the system's payment gateway became the target of a malicious cyber attack. Hackers manipulated the system, causing severe glitches during the fee payment process.

Here are the key facts:

• 50 Students Affected: The hack specifically impacted around 50 students who were attempting to pay the fees for re-evaluation and verification.

• Abnormal Fee Displays: Due to the manipulation, the portal showed wildly inaccurate payable amounts. In some cases, the fee dropped to just Re 1, while for others, it skyrocketed to nearly ₹67,000 to ₹68,000.

• Payment Gateway Targeted: The vulnerability was linked to the HDFC payment gateway that was originally integrated with the portal.

Is Student Data Safe?

Yes. Ministry officials and CBSE have confirmed that the attack was strictly isolated to the payment interface. No student data, academic records, or answer sheets were breached during this specific payment gateway incident. The disruption was purely financial in nature.

How is CBSE Fixing the Issue?

The government and the education board have taken swift action to overhaul the portal's security and restore functionality:

1. Expert Intervention: Technical experts from IIT Madras and IIT Kanpur, along with the Digital Infrastructure Corporation of India, have been brought in to audit the backend code and secure the payment architecture.

2. New Payment Gateways: CBSE has removed the affected payment gateway and integrated four major public sector banks—State Bank of India (SBI), Canara Bank, Indian Bank, and Bank of Maharashtra—to handle transactions securely.

3. Upgraded Infrastructure: To handle heavy traffic and ensure scalability, the entire portal system has been migrated to Amazon Web Services (AWS).

4. Refunds Initiated: For students who ended up paying inflated fees due to the glitch, CBSE is actively processing immediate refunds.

What Should Students Do Next?

Due to the disruption, the revaluation portal was temporarily taken down. However, following successful test runs of the newly secured system, the portal has officially reopened as of today, June 1, 2026.

If you are a Class 12 student looking to submit question-wise objections or apply for re-evaluation:

• You can now safely log back into the CBSE portal.

• Ensure you are using the official CBSE website to avoid phishing scams.

• If you experience any lingering payment issues, reach out to your school's administration or the CBSE regional office immediately.
