The board has also strengthened the portal's security and technical infrastructure. Students can now more easily verify details, complete applications, and report evaluation discrepancies

India's cybersecurity watchdog, CERT-In, has issued a high-alert advisory to MSMEs regarding advanced AI systems like Mythos. These powerful AI models can now identify software flaws, automate attacks, and generate phishing content at unprecedented speeds, significantly lowering the barrier for cybercriminals and posing substantial risks to businesses with weaker defenses.

A massive international crackdown, Operation PowerOFF, has targeted over 75,000 users of illegal DDoS-for-hire services. Europol and 21 nations disrupted criminal infrastructure, leading to arrests, domain takedowns, and warning campaigns. This operation aims to dismantle easy-to-access cybercrime tools and prevent future attacks on businesses and individuals globally.

The US Justice Department has disrupted four global botnets, Aisuru, KimWolf, JackSkid, and Mossad, which infected over 3 million devices worldwide. These botnets were used to launch massive Distributed Denial of Service (DDoS) attacks, impacting millions of IoT devices and even systems connected to the Department of Defense.

Microsoft's Azure successfully defended against the largest cloud DDoS attack ever recorded, peaking at 15.72 Tbps and nearly 3.64 billion packets per second. The Aisuru botnet, exploiting compromised IoT devices, launched the massive UDP flood targeting a single Australian customer. This incident highlights the escalating threat landscape as internet speeds and IoT capabilities advance.

Elon Musk's social media platform X (formerly Twitter) experienced a DDoS attack, causing delays before a scheduled conversation with former U.S. President Donald Trump. The incident highlighted the serious nature of such attacks, which overwhelm services with excessive traffic. ddos attacks disrupt platforms, leading to potential financial losses, data issues, and user dissatisfaction.

Tesla CEO Elon Musk's anticipated interview with Republican Presidential candidate Donald Trump on X was disrupted by a Distributed Denial of Service (DDoS) attack. Despite initial plans for 8 million listeners, Musk announced the conversation would proceed with a smaller audience and the full audio posted later. The attack hindered platform functionality, prompting measures to contain it.

A Distributed Denial of Service (DDoS) attack is designed to stop a website from functioning normally or disrupt it completely. During an attack (which usually targets government institutions, retail or financial companies, media or other organizations). According to Kaspersky experts, this is a standard picture: A relatively calm summer is followed by a sharp surge in DDoS activity.

According to I4C CEO Rajesh Kumar, the 16 lakh bot attacks were part of an attempted distributed-denial-of-service (DDoS) attack. The aim of a DDoS attack is to overwhelm a network by flooding it with superfluous traffic so it can't handle requests from legitimate users. "When you do a DDoS attack, the attacker creates bots and they act on the attackers' behalf. They send multiple requests that the system can't handle," he said, adding they were treating one DDoS attack involving 16 lakh bots as "one security incident".

In a blog post, Google said that back on June 1, a Google Cloud Armor customer was targeted with a series of HTTPS ddos attacks which peaked at 46 million requests per second. As per Google, this is the largest Layer 7 DDoS reported to date.

Here, we throw some light on the strategies used by cyber experts to mitigate a DDoS cyberattack.

Computer security analysts have issued an alert for Internet users and operators against hackers attempting to target websites of "reputed" government and private organisations.

Google has revealed that it had faced one of the biggest DDoS cyber attacks back in 2017 clocking at 2.5 Tbps (bits per second) over a period of six months. The researchers claimed that the attack originated from China and had used the network of four internet service providers in China. The attackers expected to get past Google’s past automated defences to disrupt services.

Zoom experienced a significant global outage on Friday, disrupting video meetings, its website, and mobile apps, leaving numerous users unable to connect. The company acknowledged domain name resolution issues and later confirmed service restoration. While investigating the cause, a hacking group, DarkStorm, claimed responsibility for a DDoS attack, though Zoom has not confirmed this.

Wikipedia has banned Archive.today after discovering it launched a DDoS attack on a blogger by embedding malicious JavaScript. The archive site allegedly altered web page snapshots to include the blogger's name. This move, effective immediately, aims to protect readers and maintain Wikipedia's integrity, despite some concerns about verifiability.

Google, Microsoft, Amazon, and Cloudflare have successfully mitigated a massive DDoS cyber attack that targeted their services. Referred to as "HTTP/2 Rapid Reset," the attack exploited a zero-day vulnerability in the HTTP/2 network protocol. The companies developed technology and added additional protections to counter similar attacks, which peaked in August 2023.

Officials say the European parliament website has been affected because of a hacking attack. European Parliament spokesman Jaume Duch said Wednesday that the website “is currently impacted from outside due to high levels of external network traffic.” He added that “this traffic is related to a DDOS attack (Distributed Denial of Service) event.”

India topped the global top 50 ranking of countries that have witnessed the highest volume of ‘originating distributed denial of service (DDoS) traffic’.

Earlier this month, Microsoft 365 suite, which includes Outlook, Word and Excel, was down for thousands of users, outage tracking website Downdetector showed. At that time, Microsoft 365 Status account tweeted about the outage that occurred on June 5, and a day later said that it got things under control. However, the company was investigating the cause of the outage and it has now added that outages were caused by a Distributed Denial-of-Service (DDoS) attack.

To prevent attacks on connected gadgets, users must update their devices, monitor networks, and follow network security best practices. Hackers exploit vulnerabilities, so staying updated is crucial. Stefan Zuger from Fortinet advises protecting devices against malware and suspicious activity to stay safe from cybercriminals.

DDoS stands for Distributed Denial of Service. In other words, a ‘denial of service’ to the regular online traffic of a particular website or service. In this type of cyberattack, the cyber perpetrators send a huge chunk of data over an online network/service/server to overwhelm it, to basically bring it down or make it stop functioning.

During Operation Sindoor, India faced intense cyberattacks from state-backed hackers and hacktivists across multiple nations, targeting critical infrastructure and defense systems. These attacks, peaking in early May 2025, involved ddos attacks and attempts to extract sensitive information. Pro-Indian hacktivist groups emerged to counter these threats, highlighting the escalating cyber warfare landscape.

An airline in Mumbai experienced two ddos attacks within eight months, disrupting operations and sales. The unidentified attacker warned the airline on social media and demanded action to stop the attacks. Cyber police are investigating, with no monetary demands made. Multiple IP addresses were used, indicating a complex attack strategy.

Cloudflare has successfully defended against the largest publicly disclosed DDoS attack, a 'hyper-volumetric' bombardment by the Aisuru/Kimwolf botnet peaking at 31.4 Tbps. The 'Night Before Christmas' campaign, originating from compromised Android TVs, targeted various organizations including Cloudflare's own infrastructure. Automated systems detected and mitigated these intense, short-lived attacks without human intervention.
