The environmental services industry witnessed an "unprecedented surge" in HTTP-based distributed denial-of-service (DDoS) attacks, accounting for half of all its HTTP traffic. This marks a 61,839% increase in DDoS attack traffic year-over-year, web infrastructure and security company Cloudflare said in its DDoS threat report for 2023 Q4 published last week. "This surge in cyber attacks coincided with  COP 28 , which ran from November 30th to December 12th, 2023," security researchers Omer Yoachimik and Jorge Pacheco  said , describing it as a "disturbing trend in the cyber threat landscape." The uptick in HTTP attacks targeting environmental services websites is part of a larger trend observed annually over the past few years, specifically during COP 26 and COP 27, as well as other United Nations environment-related resolutions or announcements. "This recurring pattern underscores the growing intersection between environmental issues and cyber security, a nexus that is increasingl

Cloudflare on Tuesday disclosed that it had acted to prevent a record-setting 26 million request per second (RPS) distributed denial-of-service (DDoS) attack last week, making it the largest HTTPS DDoS attack detected to date. The web performance and security company said the attack was directed against an unnamed customer website using its Free plan and emanated from a "powerful" botnet of 5,067 devices, with each node generating approximately 5,200 RPS at peak. The botnet is said to have created a flood of more than 212 million HTTPS requests within less than 30 seconds from over 1,500 networks in 121 countries, including Indonesia, the U.S., Brazil, Russia, and India. Roughly 3% of the attack came through Tor nodes. The attack "originated mostly from Cloud Service Providers as opposed to Residential Internet Service Providers, indicating the use of hijacked virtual machines and powerful servers to generate the attack — as opposed to much weaker Internet of Things

In today's digital world, where connectivity is rules all, endpoints serve as the gateway to a business's digital kingdom. And because of this, endpoints are one of hackers' favorite targets.  According to the IDC,  70% of successful breaches start at the endpoint . Unprotected endpoints provide vulnerable entry points to launch devastating cyberattacks. With IT teams needing to protect more endpoints—and more kinds of endpoints—than ever before, that perimeter has become more challenging to defend. You need to improve your endpoint security, but where do you start? That's where this guide comes in.  We've curated the top 10 must-know endpoint security tips that every IT and security professional should have in their arsenal. From identifying entry points to implementing EDR solutions, we'll dive into the insights you need to defend your endpoints with confidence.  1.

DDOS attack on Change.org from China ! Change.org, an online petitioning platform, has come under an ongoing distributed denial of service (DDoS) attack originating from China after the site hosted a call urging Chinese authorities to release artist Ai Weiwei from custody. The attacks, which started late Sunday, have nearly brought down the site, according to Change.org founder Ben Rattray. DDoS attacks work by using hundreds or thousands of hacked computers to send traffic to a website, overwhelming it with data so it becomes inaccessible to normal users. Change.org said the current attack originates from an expanding group of computers primarily based in China, and has yet to stop. This is the first time the site has been hit with a DDoS attack. Change.org has been hosting a online petition calling for the release of Chinese artist Ai Weiwei, who is currently under arrest. The petition has attracted almost 100,000 people from 175 countries, making it one of Change.org'

The Geneva-based encrypted email service ProtonMail was forced to pay a  Ransom of almost $6,000 to stop sustained Denial-of-service (DDoS) attacks that have knocked its service offline since Tuesday. ProtonMail – a full, end-to-end encrypted email service that launched last year – has been dealing with, what it called, the extremely powerful DDoS attack, and is still unavailable at the time of writing. ProtonMail Paid $6,000 to Stop DDoS In an official statement posted on a WordPress blog Thursday, officials of ProtonMail said the powerful DDoS attack by an unknown group of hackers forced them to pay 15 Bitcoins (about $5,850) in exchange for them halting the assault. However, even after paying the ransom amount, the crippling DDoS attacks continued to the ProtonMail service. DDoS Attack Continues Even After Paying Ransom ProtonMail officials said, "We hoped that by paying [ransom], we could spare other companies impacted by the [DDoS] attack again

Github – the popular code sharing website used by programmers to collaborate on software development – again became a victim of a distributed-denial-of-service (DDoS) attack on Tuesday morning. The attack came just a few months after the popular code repository website GitHub suffered a massive DDoS attack, which was linked to China. Also Read: China Using A Powerful 'Great Cannon' Weapon to Censor The Internet The company was made aware of the issue early on Tuesday. After investigating the problem, the team discovered that the service was under a new DDoS attack. The code repository disclosed the new attack on its status page as well as its official Twitter account. "The connectivity problems have been identified as a DDoS attack. We're working to mitigate now," GitHub status log read early on Tuesday. The March DDoS attack against GitHub lasted close to a week . At the time, the attackers used malicious JavaScript to hijack Internet

Yesterday, the most popular RSS reader Feedly was down as a result of a large scale distributed-denial-of service (DDoS) attack carried by the cybercriminals to extort money. On Wednesday, the Feedly was temporarily unavailable for its users. Feedly posted details of the attack at 5:00 AM ET on its blog saying that they were under a Distributed Denial of Service (DDoS) attack and cyber-criminals were demanding money in return for returning the service to its normal operations. " Criminals are attacking feedly with a distributed denial of service attack (DDoS). The attacker is trying to extort us money to make it stop, " Edwin Khodabakchian, founder and CEO of Feedly said in a statement on Wednesday. He also expressed regret, " We want to apologize for the inconvenience. Please know that you data is safe and you will be able to re-access your feedly as soon as the attack is neutralized. " Feedly is a very popular RSS feed service which is available for desktop, iOS and

Someone just DDoSed one of the most critical organs of the Internet anatomy – The Internet's DNS Root Servers . Early last week, a flood of as many as 5 Million queries per second hit many of the Internet's DNS ( Domain Name System ) Root Servers that act as the authoritative reference for mapping domain names to IP addresses and are a total of 13 in numbers. The attack, commonly known as Distributed Denial of Service (DDoS) attack, took place on two separate occasions. The first DDoS attack to the Internet's backbone root servers launched on November 30 that lasted 160 minutes ( almost 3 hours ), and the second one started on December 1 that lasted almost an hour. Massive Attacks Knocked Many of the 13 Root Servers Offline The DDoS attack was able to knock 3 out of the 13 DNS root servers of the Internet offline for a couple of hours. Also Read:  Secure Email Service Paid Hackers $6000 Ransom to Stop DDoS Attacks . The request queries fired

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 (IoT)  is transforming efficiency in various sectors like healthcare and logistics but has also introduced new security risks, particularly IoT-driven DDoS attacks. This article explores how these attacks work, why they're uniquely problematic, and how to mitigate them. What Is IoT? IoT (Internet of Things) refers to online, interconnected devices that collect and exchange data. This broad category of devices includes sensors, cameras, network routers, and advanced machinery, and their integration into everyday life and work processes results in an ecosystem that can automate operations, improve decision-making, and enhance user experience. IoT: A Breeding Ground for Botnets IoT's rapid adoption amplifies its vulnerability, as poorly secured devices become easy prey for attackers and may become part of a botnet. Controlled by attackers, botnets can scale and rapidly execute various attacks, including DDoS, data theft, ad fraud, cryptocurrency mining, spam a

Cloudflare on Thursday said it mitigated thousands of hyper-volumetric HTTP distributed denial-of-service (DDoS) attacks that exploited a recently disclosed flaw called  HTTP/2 Rapid Reset , 89 of which exceeded 100 million requests per second (RPS). "The campaign contributed to an overall increase of 65% in HTTP DDoS attack traffic in Q3 compared to the previous quarter ," the web infrastructure and security company said in a report shared with The Hacker News. "Similarly,  L3/4 DDoS attacks  also increased by 14%." The total number of HTTP DDoS attack requests in the quarter surged to 8.9 trillion, up from 5.4 trillion in Q2 2023 and 4.7 trillion in Q1 2023. The number of attack requests in Q4 2022 stood at 6.5 trillion. HTTP/2 Rapid Reset (CVE-2023-44487) came to light earlier this month following an industry-wide coordinated disclosure that delved into DDoS attacks orchestrated by an unknown actor by leveraging the flaw to target various providers such as

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
