According to the education body, the attacks involved large volumes of malicious traffic from multiple IP addresses in India and abroad
The Central Board of Secondary Education (CBSE) has filed a formal complaint with the Delhi Police after its post-results services portal came under a series of coordinated cyber attacks.
The portal, launched on June 2 for Class 12 students seeking services such as verification of marks and re-evaluation of answer scripts, was targeted by repeated attacks over three days.
According to CBSE, the attacks involved large volumes of malicious traffic from multiple IP addresses in India and abroad, with the apparent aim of disrupting access for legitimate users and attempting unauthorized extraction of information.
“The attacks were successfully mitigated through continuous 24×7 monitoring and response mechanisms,” CBSE said in a statement.
The board said it approached Delhi Police for a detailed investigation and legal action against those responsible, adding that no data breach or unauthorised access had been detected. “Despite these malicious attempts, CBSE’s systems and databases remain secure and uncompromised. No data breach or unauthorised access has been detected.”
The attacks come at a critical time for students, as the portal is used by thousands of students across the country to access post-result services.
According to an earlier press release from CBSE, the portal will remain open until midnight on June 6, allowing students sufficient time to complete their applications for verification and re-evaluation.
However, some students continued to report technical issues and glitches on June 5, raising concerns over accessibility and timely submission of forms.
One user wrote on X: “The revaluation payment page is stuck in an endless loading loop and my transaction won’t go through. Please fix this portal glitch soon as deadlines are approaching!”
Responding to the complaint, CBSE replied to the post and shared a video tutorial with step-by-step instructions to help users complete the payment process and navigate the portal successfully.
On June 4, X user Aparna779068 also reported reported technical difficulties.
Dear CBSE,
I spent hours trying on the website for re-evaluation, but even after filling in all the details correctly, I’m repeatedly getting an error and the form is not submitting. The last date is approaching. Please resolve this technical glitch quickly.@cbseindia29 pic.twitter.com/jCZ9efD9GL— Aparna (@Aparna779068) June 4, 2026
