The Central Board of Secondary Education (CBSE) said on Tuesday that its Class 12 re-evaluation portal came under multiple cyberattack attempts on the day it was opened for students, but the platform continued to function normally, handling thousands of applications.
The portal has been open since 4 am, but has experienced glitches.
According to the CBSE, the portal is currently supporting more than 8,000 concurrent users. “As of 3 pm, over 16,000 students had completed their submissions for verification of marks and that re-evaluation.”
The CBSE said “malicious actors” attempted to disrupt services through a series of cyberattacks, including a denial-of-service (DoS) attack that generated nearly 1.5 million hits on the portal within two minutes. The board also reported more than one lakh attempts at unauthorised file access during the same period.

The CBSE said its technical teams were able to maintain the portal’s operations despite the attacks and ensure that students continued to access the services without major disruptions.
“Based on student feedback, we have further refined the platform, including extending session time limits to make the process more convenient and seamless,” the board said in a statement.
The CBSE added that its teams remain on high alert and are continuously monitoring the system to safeguard the platform and facilitate students using the post-result services.

The re-evaluation portal gives Class 12 students an opportunity to apply for verification of marks and re-evaluation of answer sheets after obtaining copies of their evaluated scripts. The process assumes significance this year amid heightened scrutiny of the board’s evaluation and post-result mechanisms.
