The Central Board of Secondary Education (CBSE) has confirmed that a reported compromise of its On-Screen Marking (OSM) portal on February 26, 2026, involved a fake testing site. The board stated the compromised URL, http://cbse.onmarks.co.in, was a mock testing platform, not the live system used for actual student assessments. This testing site contained fabricated data and served no purpose related to real student evaluations.
CBSE officials clarified that the actual production portal, where answer scripts are evaluated and marks are recorded, operates on a separate and secure environment. This live portal was not affected by the incident and did not exhibit the security vulnerabilities claimed on social media. Therefore, the integrity of student data and recorded marks remains intact.
Data Integrity Unaffected
The board reiterated that the testing site did not store any real evaluation data, actual student marks, or personal student information. They expressed confidence in the security of the production portal used for live evaluations. No security breaches have been reported on this official system.
The incident at the testing site has no bearing on recorded marks. The fundamental integrity of the CBSE assessment processes remains secure. The OSM system is designed to enhance transparency in the evaluation process. It also includes established procedures for addressing student grievances.
Guidance for Students and Parents
CBSE advises students and parents to rely on official communications. Information should be sourced directly from the CBSE official website and from schools. Avoid engaging with unverified social media posts that can cause unnecessary anxiety.
If you suspect an error in your paper's evaluation or your allotted marks, follow the formal grievance procedure outlined by CBSE. Do not act on rumors. The reported compromise concerned a non-production testing site with sample data only.
CBSE assures all stakeholders that robust safeguards are in place. These measures protect the secure evaluation environment and student information on the live platform. All concerns should be addressed through the established grievance mechanisms, and information should be sought from official notifications.
