CBSE Row: The Central Board of Secondary Education (CBSE) on Friday lodged a complaint with the Delhi Police regarding coordinated cyber attacks on its Post-Result Services Portal. All attacks were successfully mitigated through 24×7 monitoring, with no data breach or compromise of systems, it said.
The development comes at a time when the CBSE is under fire over the On-Screen Marking (OSM) evaluation issue. The CBSE is facing criticism after some class 12 students alleged that the scanned copies of their answer sheets uploaded by the board did not match their handwriting, raising concerns over possible answer-sheet mismatch in the On-Screen Marking (OSM) system. Recently, a 19-year-old ethical hacker, Nisarga Adhikary, exposed multiple critical vulnerabilities in the CBSE's OSM evaluation portal. However, the board maintained that the compromised site was a testing portal with sample data rather than the live evaluation system.
Big Action By The Govt Over OSM Issue
Following the row over the OSM issue, the Central government on June 2 transferred CBSE chairman Rahul Singh and secretary Himanshu Gupta, replacing them with Lokhande and Varun Bhardwaj, respectively, amid alleged irregularities in the Class 12 digital evaluation system.

The CBSE had also said that 'malicious actors' attempted to disrupt services on its re-evaluation portal through a barrage of cyberattacks, including a denial-of-service attack that caused 1.5 million hits on the platform within two minutes and more than one lakh attempts at unauthorised file access.
CBSE Says 3.8 Million-Packet DoS Attack Thwarted
Earlier on June 3, the CBSE said it successfully thwarted a 3.8 million-packet denial-of-service (DoS) attack on its website, while over 56,000 applications for verification and re-evaluation were received till 9:30 pm.
"Our technical teams are proactively monitoring performance and introducing refinements to deliver a smoother, faster and more seamless experience for students," it said. Payment gateways of State Bank of India (SBI), Canara Bank, Bank of Baroda and Indian Bank are available on the verification and re-evaluation portal, the CBSE said, adding that students are not required to have an account with these banks to complete the payment process.
