CBSE Addresses and Contains Vulnerabilities in OnMark Portal with Expert Cybersecurity SupportPreviousNext

The Central Board of Secondary Education (CBSE) has acknowledged and contained cybersecurity vulnerabilities in its OnMark portal, used for Class 12 answer sheet evaluations. Following public concerns raised by a 19-year-old ethical hacker and others, CBSE deployed cybersecurity experts from government agencies and Indian Institutes of Technology (IITs) to strengthen the system. The board thanked ethical hackers and alert citizens for flagging issues and is conducting further checks while transitioning to a more secure setup. CBSE affirmed no student data was compromised and invited additional security reports.
