Overview
- The board’s post‑result portal remained live and had processed 70,433 successful applications by June 4 for verification and re‑evaluation, and the application window closes at 11:59 pm on June 7.
- CBSE says its systems sustained a coordinated Denial‑of‑Service event on June 3 that sent nearly 3.8 million malicious packets but was mitigated with no confirmed data breach.
- Within two minutes of the portal going live on June 2 the platform recorded about 1.5 million access requests and blocked more than 100,000 unauthorised attempts, placing heavy load on the system.
- The board lodged a formal complaint with Delhi Police’s IFSO unit and an FIR was registered on June 5 while cybersecurity teams from IIT Kanpur, IIT Madras, CERT‑In and central agencies carry out 24×7 monitoring and technical audits.
- Researchers had earlier flagged concrete OSM flaws such as a plaintext master password, client‑side login checks, and a password reset weakness that could let attackers impersonate examiners, prompting transfers of senior CBSE officials and a procurement inquiry that could affect trust in digital exam systems.
