For thousands of Class 12 students across India, the window to get their answer sheets rechecked or verified is closing fast. But just as the CBSE opened its post-result services portal on June 2, something else arrived — a barrage of malicious traffic that threatened to shut it down.
What happened: Cyberattacks hit CBSE portal days after launch
Delhi Police has registered an FIR and launched an investigation into a series of alleged cyberattacks targeting the Central Board of Secondary Education's post-result services portal, the board confirmed on Friday, June 5. The case was registered under Sections 66 and 43(f) of the Information Technology Act after CBSE lodged a formal complaint with the Intelligence Fusion and Strategic Operations (IFSO) unit of Delhi Police.
According to the board, the portal — which went live on June 2 to facilitate services such as verification and re-evaluation of Class 12 answer sheets — came under repeated attacks over three days. The attacks involved large volumes of malicious traffic originating from multiple sources, officials said.
Why this matters for students and parents right now
For students waiting on re-evaluation results that could change their college admissions or career paths, any disruption to the portal is deeply stressful. The CBSE confirmed that despite the attacks, the portal has remained operational and has already accepted over 56,000 applications for marks verification and re-evaluation. But with the deadline approaching, every hour of downtime matters.
Parents and students have been anxiously checking the portal, unsure if technical glitches are due to high traffic or something more sinister. The cyberattack adds an extra layer of uncertainty to an already tense period.
Timeline: How the attacks unfolded
The post-result services portal was launched on June 2, allowing students to apply for verification of marks, re-evaluation of answer sheets, and obtaining photocopies of evaluated answer books. Within hours of going live, the portal began receiving unusually high volumes of traffic.
Over the next three days, CBSE officials observed repeated spikes in malicious traffic — a pattern consistent with Distributed Denial of Service (DoS) attacks, where attackers flood a server with requests to overwhelm it. The board moved quickly to lodge a formal complaint with Delhi Police's IFSO unit, which specializes in cybercrime investigations.
Who is affected: Students, schools, and the education system
The Class 12 board results are a critical milestone for Indian students, determining college admissions, scholarship eligibility, and career trajectories. Any delay or disruption to the re-evaluation process can have real consequences — missed application deadlines for universities, added anxiety, and financial costs for families who paid for re-evaluation services.
Schools that rely on the portal to submit bulk applications on behalf of students are also affected. Teachers and administrators have reported difficulties accessing the portal during peak hours, though CBSE maintains the system is functioning.
Official response: What CBSE and Delhi Police have said
In a statement, CBSE said: "The portal has come under repeated attacks over the past three days, involving large volumes of malicious traffic originating from multiple sources." The board confirmed that a formal complaint has been lodged with Delhi Police's IFSO unit, and an FIR has been registered under Sections 66 and 43(f) of the IT Act.
Delhi Police has not yet released details about potential suspects or the origin of the attacks. The IFSO unit is known for handling complex cybercrime cases, including those targeting government infrastructure.
Analysis: Why target a CBSE portal?
Cyberattacks on educational portals are not new in India. In recent years, university admission portals, exam result websites, and board examination systems have all been targeted by malicious actors — sometimes by disgruntled individuals, sometimes by groups seeking to cause disruption, and occasionally by hackers testing their skills.
The CBSE portal handles sensitive student data, including personal information, marks, and financial transactions for re-evaluation fees. A successful attack could compromise data integrity or cause prolonged service disruption. Security experts say DoS attacks are often used as a smokescreen for more serious breaches, though CBSE has not reported any data theft.
Confirmed facts vs what remains unclear
Confirmed: Delhi Police has registered an FIR under IT Act Sections 66 and 43(f). The attacks involved large volumes of malicious traffic over three days. The portal remains operational. Over 56,000 applications have been submitted. The case is being investigated by the IFSO unit.
Unclear: The identity and motive of the attackers. Whether any student data was accessed or compromised. Whether the attacks are linked to any broader cybercrime network. The exact nature of the malicious traffic (DoS vs other methods).
Wider trend: Cyberattacks on Indian education infrastructure
This incident is part of a worrying pattern. Indian educational institutions — from school boards to universities — have become frequent targets of cyberattacks. In 2024, several university admission portals faced disruptions during peak application periods. The AIIMS Delhi ransomware attack in 2022 exposed vulnerabilities in public health education systems.
Experts say the education sector often underinvests in cybersecurity, making it an attractive target. The CBSE incident highlights the need for robust security measures, especially during high-stakes periods like result announcements and re-evaluation windows.
Practical guidance for students and parents
If you are a student waiting to apply for re-evaluation or marks verification: Submit your application as early as possible before the deadline. Keep screenshots or confirmation receipts of your application. If you face technical issues, contact CBSE's helpline or email support. Avoid sharing your login credentials or personal information on unofficial websites. Monitor official CBSE channels for updates.
Parents should ensure their children use only the official CBSE portal for applications. Be cautious of third-party websites claiming to offer faster re-evaluation services — these could be phishing attempts.
What happens next
Delhi Police's IFSO unit will trace the source of the malicious traffic, analyze server logs, and attempt to identify the attackers. CBSE has said it will continue to keep the portal operational and may extend the deadline if disruptions persist, though no official extension has been announced yet.
Students should expect the re-evaluation process to proceed as scheduled, with results likely announced in the coming weeks. The investigation may take months, and if suspects are identified, they could face charges under the IT Act, which carries penalties including imprisonment.
Our Take
This incident is a reminder that India's education infrastructure remains vulnerable to cyber threats at the worst possible times. While CBSE and Delhi Police have acted swiftly, the attack itself raises uncomfortable questions: Why wasn't the portal better protected? How many other government education systems are equally exposed?
For students, the immediate concern is getting their applications through. But for policymakers, the lesson is clear — cybersecurity cannot be an afterthought in a system that handles the futures of millions of young Indians.
