CBSE Re-evaluation Portal Faces Cyberattack Attempts as Over 16,000 Students Submit Applications

The Central Board of Secondary Education (CBSE) has reported that its re-evaluation portal faced multiple cyberattack attempts on June 2, 2026, even as thousands of students logged in to apply for verification of answer books and re-evaluation of marks. According to the board, the platform remained operational despite the attacks and successfully handled heavy traffic from students across the country.

CBSE Re-evaluation Portal Faces Cyberattack Attempts as Over 16,000 Students Submit Applications

CBSE stated that the portal was managing more than 8,000 concurrent users at a time and had processed over 16,000 student submissions by 3 PM. The board identified the incidents as Denial-of-Service (DoS) attack attempts, which are designed to overwhelm online systems with excessive traffic. However, officials confirmed that the portal's security infrastructure effectively mitigated the attacks and ensured uninterrupted access for users.

The development comes amid heightened scrutiny of CBSE's digital evaluation ecosystem. Over the past few days, students and parents have raised concerns regarding delays in portal activation, issues related to scanned answer sheets, and cybersecurity vulnerabilities highlighted by independent researchers. These concerns gained attention after discussions and updates shared on social media platforms.

CBSE had originally planned to open the re-evaluation portal earlier but postponed the launch before making it available on June 2. The board clarified that students who had already obtained scanned copies of their evaluated answer books could now proceed with applications for verification and re-evaluation.

What Students Can Apply For

Students are permitted to request verification and raise concerns regarding:

• Missing pages in scanned answer books
• Missing supplementary answer sheets

The board has advised students to carefully review their scanned answer sheets before submitting requests.
