On Wednesday, February 28, 2018, GitHub's code hosting website hit with the largest-ever distributed denial of service (DDoS) attack that peaked at record 1.35 Tbps. Interestingly, attackers did not use any botnet network, instead weaponized misconfigured Memcached servers to amplify the DDoS attack. Earlier this week we published a report detailing how attackers could abuse Memcached, popular open-source and easily deployable distributed caching system, to launch over 51,000 times powerful DDoS attack than its original strength. Dubbed Memcrashed , the amplification DDoS attack works by sending a forged request to the targeted Memcrashed server on port 11211 using a spoofed IP address that matches the victim's IP. A few bytes of the request sent to the vulnerable server trigger tens of thousands of times bigger response against the targeted IP address. "This attack was the largest attack seen to date by Akamai, more than twice the size of the September 2016

It should be the busiest day of the year for your business, but your website has just disappeared off the Internet and orders have dried up. If this happens to you, then you likely just become yet another victim of a distributed denial of service (DDoS) attack . By now, everyone who uses the Internet has come across DDoS attacks . It is one of the oldest attack technologies on the web, and a popular way of paralyzing the huge data centers. Just yesterday we have reported about a massive 100Gbps DDoS attack that hit World's 3rd Largest Chinese Bitcoin exchange for 9 hours. Arbor Networks, a leading provider of DDoS and advanced threat protection solutions, today released data on global distributed denial of service (DDoS) attack trends for the first three quarters of 2013, revealed that this kind of attack still represents a serious menace for IT security communities.  The document provides an interesting overview into Internet traffic patterns and threat evolutio

UPDATE — How an army of million of hacked Internet-connected smart devices almost broke the Internet today. Cyber attacks are getting evil and worst nightmare for companies day-by-day, and the Distributed Denial of Service (DDoS) attack is one such attacks that cause a massive damage to any service. Recently, the Internet witnessed a record-breaking largest DDoS attack of over 1 Tbps against France-based hosting provider OVH, and now the latest victim of the attack is none other than Dyn DNS provider. A sudden outage of popular sites and services, including Twitter, SoundCloud, Spotify, and Shopify, for many users, is causing uproar online. It's because of a DDoS attack against the popular Domain Name System (DNS) service provider Dyn, according to a post on Ycombinator . DNS act as the authoritative reference for mapping domain names to IP addresses. In other words, DNS is simply an Internet's phone book that resolves human-readable web addresses, like thehackerne

Cloudflare on Wednesday disclosed that it acted to mitigate a 15.3 million request-per-second (RPS) distributed denial-of-service (DDoS) attack. The web infrastructure and website security company called it one of the "largest HTTPS DDoS attacks on record."  "HTTPS DDoS attacks are more expensive in terms of required computational resources because of the higher cost of establishing a secure TLS encrypted connection," Cloudflare's Omer Yoachimik and Julien Desgats  said . "Therefore it costs the attacker more to launch the attack, and for the victim to mitigate it." The volumetric DDoS attack is said to have lasted less than 15 seconds and targeted an unnamed Cloudflare customer operating a crypto launchpad.  Volumetric DDoS attacks are designed to overwhelm a target network/service with significantly high volumes of malicious traffic, which typically originate from a botnet under a threat actor's control. Cloudflare said the latest attack w

At the beginning of January, Gcore faced an incident involving several L3/L4 DDoS attacks with a peak volume of 650 Gbps. Attackers exploited over 2000 servers belonging to one of the top three cloud providers worldwide and targeted a client who was using a free CDN plan. However, due to Gcore's distribution of infrastructure and a large number of peering partners, the attacks were mitigated, and the client's web application remained available. Why was mitigating these attacks so significant? 1. These attacks were significant because they exceeded the average bandwidth of similar attacks by 60×.  The performed attacks relate to volume-based attacks targeted to saturate the attacked application's bandwidth in order to overflow it. Measuring total volume (bps)—rather than the number of requests—is the way these attacks are usually tabulated. The average bandwidth of this attack type is generally in the tens of Gbps (about 10 Gbps). Therefore, the specified attacks (at 650 Gbps) excee

The Internet of Things (IoTs) or Internet-connected devices are growing at an exponential rate and so are threats to them. Due to the insecure implementation, these Internet-connected embedded devices, including Smart TVs, Refrigerators, Microwaves, Set-top boxes, Security Cameras and printers, are routinely being hacked and used as weapons in cyber attacks. We have seen how hackers literally turned more than 100,000 Smart TVs and Refrigerator into the cyber weapon to send out millions of malicious spam emails for hacking campaigns; we have also seen how hackers abused printers and set-top-boxes to mine Bitcoins. And now… Cyber crooks are hacking CCTV cameras to form a massive botnet that can blow large websites off the Internet by launching Distributed Denial-of-service (DDoS) attacks. Researchers at Security firm Sucuri came across a botnet of over 25,000 CCTV cameras targeting business around the globe while defending a small jewelry shop against a DDoS attack . Al

The DDoS techniques have massively increased with the attackers becoming more skillful at working around the network security. A massive 300Gbps DDoS attack launched against Spamhaus website almost broke the Internet a year ago and also earlier this year, hackers have succeeded in reaching new heights of the massive DDoS attack targeting content-delivery and anti-DDoS protection firm CloudFlare, reaching more than 400Gbps at its peak of traffic. Akamai's Prolexic Security Engineering and Response Team (PLXsert) issued a threat advisory on Thursday reporting a significant surge in DDoS attacks last month abusing the Simple Network Management Protocol (SNMP) interface in network devices. Simple Network Management Protocol (SNMP) is a UDP-based protocol which is commonly known and often used to manage network devices. SNMP is typically used in devices such as printers, routers and firewalls that can be found in the home and enterprise environments as well. Just as D

In March of this year, we saw the first ever 300 Gigabit DDoS attack , which was possible due to a DNS Reflection Amplification attack against Spamhaus . On 24 September World's 3rd Largest Bitcoin exchange BTC China , a platform where both Bitcoin and Chinese yuan are traded faced massive DDoS attack for continued nine hours, where no amplification techniques were used. Incapsula , Cloud-based security service provider helped the Chinese Bitcoin trader to protect them from such massive denial-of-service attack and successfully mitigated the threats. Incapsula tweeted  a graph of DDoS attack last month as shown, " Yesterday we prevented a ~100Gbps DDoS. The attack's load was distributed across our 350Gbps network. " Specialist at Incapsula shared the details of the attack with TheRegister , explained " The attack against BTC China took the form of a SYN flood rather than the DNS amplification-style attack ", " The attacker balanced the assault betwee

Two weeks ago, we reported how a serious flaw in the popular peer-to-peer BitTorrent file sharing protocols could be exploited to carry out a devastating distributed denial of service (DDoS) attack, allowing lone hackers with limited resources to take down large websites. Good news is that the developers of BitTorrent have fixed the security issue in its service that is being used by hundreds of Millions of users worldwide. In a blog post published Thursday, BitTorrent announced that the flaw was resided in a reference implementation of the Micro Transport Protocol (uTP) called libuTP , which is used by many widely used BitTorrent clients such as μTorrent , Vuze and Mainline . The San Francisco company also announced that it has rolled out a patch for its libuTP software that will stop miscreants from abusing the p2p protocol to conduct Distributed Reflective Denial-of-Service (DRDoS) attacks. DRDoS attack is a more sophisticated form of conventional DDoS att

There is currently a Mega cyber attack campaign being launched on a large number of WordPress websites across the Internet.  In April, 2012 we reported about a large distributed brute force attack against millions of WordPress sites were occurring, out of that hackers are successful to compromise 90,000 servers to create a large Botnet  of Wordpress hosts. According to the DDOS attack logs report  received from a ' The Hacker News ' reader ' Steven Veldkamp ', victim's website was under under heavy DDOS attack recently, coming from various compromised Wordpress based websites. Possibly using the brute force attack on WordPress administrative portals with the a world list of the most commonly used username and password combinations, attackers are taking control of many poorly secured WordPress Hosts. After analyzing the piece of a DDOS attack Log file from timing 23/Sep/2013:13:03:13 +0200 to 23/Sep/2013:13:02:47 +0200, we found that in 26 second attacker was

Currently there are more than Million people worldwide playing Windows Games, Computer Games and Online Video Games, at least an hour a day, but the gaming servers are often insecure and misconfigured. Yesterday, a popular multiplayer Free Online Game ' Wurm ' servers were knocked offline by Distributed Denial of Service (DDoS) attack. Servers were targeted shortly after its most recent update. The Online Game company announced a Bounty Reward of  €10,000  ($13,000) for information about the attacker involved in the recent DDOS attack .  As the gaming servers go down, the company will lose gamers, reputation and revenue. The Wurn Online Game developer said: " We can offer 10,000 Euro for any tips or evidence leading to a conviction of the person responsible for this attack. " Free Online Game service was already planning to change the server, but the DDoS attack made the gaming application offline for more than a day. " Shortly after todays update we wer

Do you know — Your Smart Devices may have inadvertently participated in a record-breaking largest cyber attack that Internet has just witnessed. If you own a smart device like Internet-connected televisions, cars, refrigerators or thermostats, you might already be part of a botnet of millions of infected devices that was used to launch the biggest DDoS attack known to date, with peaks of over 1 Tbps of traffic. France-based hosting provider OVH was the victim to the record-breaking Distributed Denial of Service (DDoS) attacks that reached over one terabit per second (1 Tbps) over the past week. As the Internet of Things (IoT) or connected devices are growing at a great pace, they continue to widen the attack surface at the same time, giving attackers a large number of entry points to affect you some or the other way. 1 Tbps DDoS Attack Hits OVH IoTs are currently being deployed in a large variety of devices throughout your home, businesses, hospitals, and even entire cities (

Distributed Denial of Service (DDoS) attacks have risen enormously in past few months and, mostly, they are coming from hacked and insecure internet-connected devices, most commonly known as Internet of Things (IoT). Recent DDoS attack against DNS provider Dyn that brought down a large chunk of the Internet came from hacked and vulnerable IoT devices such as DVRs, security cameras, and smart home appliances. This DDoS was the biggest cyber attack the world has ever seen. Now, in the latest incident, at least five Russian banks have been subject to a swathe of DDoS attacks for two days, said the Russian banking regulator. The state-owned Sberbank was one of the five targets of the attacks that began on last Tuesday afternoon and lasted over the next two days. According to Kaspersky Lab, the longest attack last for 12 hours and peaked at 660,000 requests per second came from a botnet of at least 24,000 hacked devices located in 30 countries. Although the culprit appears

On Thursday, we compiled a story based on research published by a British security expert reporting that some cyber criminals are apparently using Mirai Botnet to conduct DDoS attacks against the telecommunication companies in Liberia, a small African country. In his blog post , Kevin Beaumont claimed that a Liberian transit provider confirmed him about the DDoS attack of more than 500 Gbps targeting one undersea cable servicing Internet connectivity for the entire country. Later, some media outlets also confirmed that the DDoS attack caused Internet outage in some parts of the country, citing 'slow Internet' and 'total outage' experienced by some local sources and citizens. "The DDoS is killing our business. We have a challenge with the DDoS. We are hoping someone can stop it. It's killing our revenue. Our business has frequently been targeted" an employee with one Liberian mobile service provider told PC World . Network firm Level 3 confirmed Zack Whittaker

Image Credit: Pixelbay Blockchain startups are cropping up left and right aiming to disrupt existing services and business models. These range from the trivial to potentially game-changing solutions that can revolutionize the internet as we know it. Among those that promise to change the world, most are attempting to reconstruct the entire internet infrastructure into something that is decentralized, secure, scalable, and tokenized. There are also those that aim to solve the most significant problems plaguing the digital world, particularly potentially costly and tedious security issues. We do not lack for dangers, ranging from data breaches to denial-of-service attacks, and other hacks. For the most part, there are capable SaaS and software-defined services that are capable enough in addressing the threats that involve malware and DDoS. However, blockchains offer much much more. The plague of DDoS Distributed denial-of-service or DDoS attacks involve a malicious hacke

Distributed Denial of Service (DDoS) attack is a malicious form of attack that disrupts the regular network traffic by overwhelming the website with more traffic than the server can handle. The main aim of this kind of cyberattack is to render the website inoperable. Over recent years, these kinds of attacks are increasing, fueling the demand for the  best DDoS protection  software solutions. Many unplanned data center outages are owing to DDoS attacks. The threat of DDoS is due to access to easy-to-use tools and the profit potential through extortion.  The attacks target businesses directly, leading to substantial financial and personal losses, making it critical to have robust DDoS protection software solutions in place. According to the report of  Market Research Inc , the DDoS protection Software Market is predicted to reach +14% CAGR by 2020 – 2028.  Important Statistics to illustrate the growing demand for DDoS Software Solutions Demand for the DDoS software market is on th

DDoS (Distributed Denial of Service) attacks are making headlines almost every day.  2021 saw a 434%  upsurge in DDoS attacks, 5.5 times higher than 2020.  Q3 2021 saw a 24%  increase in the number of DDoS attacks in comparison to Q3 2020.  Advanced DDoS attacks that are typically targeted, known as smart attacks, rose by 31% in the same period. Further,  73% of DDoS attacks  in Q3 2021 were multi-vector attacks that combined multiple techniques to attack the targeted systems. The largest percentage of DDoS targets (40.8%) was in the US Banks, and financial institutions were the biggest DDoS and DoS attack targets in the past couple of years.  Does this mean businesses and organizations that aren't in the banking and financial services sector are safe from  DDoS attacks ? Most definitely not! Every business is a potential DDoS target. Read on to know why and what measures to take to keep your business effectively protected.  Common DDoS Targets Even though every business can be ta
