- 19-year-old hacker claims CBSE OSM portal breach.
- Shared 'Bad Apple' video as proof of access.
- CBSE denies hack, calls it a testing site.
The Central Board of Secondary Education's (CBSE) On-Screen Marking (OSM) system portal was reportedly hacked again. Nisarg Adhikary, a 19-year-old student and self-proclaimed ethical hacker, has claimed responsibility for accessing the platform.
To support his claim, Adhikari shared a screen recording on the social media platform X, which appears to show the 'Bad Apple' video playing on the official portal address, cbse.onmark.co.in, Jagran.com reported.

The video displayed the message 'PWNED via SQLi.' In cybersecurity terminology, 'PWNED' refers to unauthorised breach or control of a system, while 'SQLi' (SQL injection) refers to a technical vulnerability that is used to gain access to a database.
'Reported Security Vulnerabilities To Agencies, CERT-In': Nisarg
The 19-year-old claimed that he had previously reported several security vulnerabilities to the relevant agencies and CERT-In. According to him, the portal had severe authentication and access control flaws that could have exposed the system to widespread unauthorised access, the report added.
The incident comes amid ongoing controversy over the CBSE OSM system, answer sheet scanning, and the re-evaluation process. This is not the first time the portal has faced such scrutiny, as the student had previously claimed to hack the official website.
CBSE Dismisses Claims As 'Misleading'
The appearance of a 'maintenance' message on the portal sparked debate among the students and parents. Social media users raised questions about why the system was suddenly put into maintenance if it had not been compromised.
However, the CBSE dismissed the claims as 'misleading'. The board clarified that the URL shared on social media linked only to a testing site that houses sample data.
The board assured that the actual evaluation system is completely secure and has not been compromised.
