CBSE reported that its re-evaluation portal faced multiple cyberattack attempts while processing over 16,000 student submissions for verification and re-evaluation of Class 12 answer sheets. The board said a denial-of-service attack generated nearly 1.5 million hits within two minutes, along with over one lakh unauthorized access attempts.

Despite the disruptions, the platform remained operational. The portal, delayed for infrastructure upgrades, will stay open until June 6 with extended session limits and improved stability for applicants.
