DDoS Attacks : A Serious unstoppable menace for IT security communities

October 18, 2013Anonymous
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

IoT Botnet — 25,000 CCTV Cameras Hacked to launch DDoS Attack

June 28, 2016Swati Khandelwal
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

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

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

BitTorrent Fixes Reflective DDoS Attack Security Flaw

August 28, 2015Swati Khandelwal
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.

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.

Github – a popular coding website used by programmers to collaborate on software development – was hit by a large-scale distributed denial of service (DDoS) attack for more than 24 hours late Thursday night. It seems like when users from outside countries visit different websites on the Internet that serve advertisements and tracking code from Chinese Internet giant Baidu , the assailants on Chinese border quietly inject malicious JavaScript code into the pages of those websites. The code instructs browsers of visitors to those websites to rapidly connect to GitHub.com every two seconds in a way that visitors couldn't smell, creating "an extremely large amount of traffic," according to a researcher who goes by the name A nthr@x . "A certain device at the border of China's inner network and the Internet has hijacked the HTTP connections went into China, replaced some JavaScript files from Baidu with malicious ones," A nthr@x wrote at Insight La

During the weekend China's Internet was taken down by a powerful distributed denial of service (DDoS) attack on the .cn domain slowed and blocked Internet access inaccessibility for hours. Security expert clarified that China could have been perpetrated by sophisticated hackers or by a single individual. The China Internet Network Information Center [ CINIC ] reported that the attack began at 02:00 local time on Sunday with a peek at 04:00 that made it the largest DDoS attack the country's networks have ever faced. The CCINIC is responsible for registering sites in the .cn domain. Before malicious coders can launch a DDoS attack, they must infect the computers of unsuspecting users, often by tricking people into installing malware on their computers. The China Internet Network Information Center confirmed the attack with an official statement informing internet users that it is gradually restoring web services and that will operate to improve the security leve

Google Public DNS Server Spoofed for SNMP based DDoS Attack

September 16, 2014Wang Wei
The Distributed Denial of Service ( DDoS ) attack is becoming more sophisticated and complex, and, according to security experts , the next DDoS vector to be concerned about is SNMP (Simple Network Management Protocol) amplification attacks. Yesterday afternoon, the SANS Internet Storm Center reported SNMP scans spoofed from Google's public recursive DNS server searching for vulnerable routers and other devices that support the protocol with DDoS traffic and are opened to the public Internet. " We are receiving some reports about SNMP scans that claim to originate from 8.8.8.8 (Google's public recursive DNS server), " wrote Johannes Ullrich, dean of research of the SANS Technology Institute and head of the Internet Storm Center. " This is likely part of an attempt to launch a DDoS against Google by using SNMP as an amplifier/reflector. " Simple Network Management Protocol (SNMP) is a UDP-based protocol designed to allow the monitoring of network-

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

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 (

17-year-old Arrested for Massive DDoS Attack on Norway's Financial Sector

July 14, 2014Wang Wei
The Norwegian police have arrested and charged a 17-year-old for a massive distributed denial-of-service (DDoS) attack earlier this week that disabled the websites of major financial institutions and other businesses in the country. Distributed Denial of Service (DDoS) attack is designed to sabotage, shut down and overload the targeted website with web traffic more than its capacity in order to make it unavailable to users. The attack targeted five major banks, two telecommunication firms, three airlines and one insurance company, as their websites and online payment systems were disrupted. The unnamed teen claimed to be a part of the hacktivist group Anonymous Norway for what was thought to be the country's biggest ever cyber-attack on businesses. Although, the Anonymous Norway, via a Twitter message, has dismissed any connection to him or the cyber attack. The youngster was a resident of Bergen, on Norway's west coast. He was arrested on Thursday morning and que

DDoS Extortionists made $100,000 without Launching a Single Attack

April 26, 2016Mohit Kumar
In Brief Cyber crooks find a new and ingenious way to make hundreds of thousands of dollars with no effort. An unknown cyber gang, pretending to be Armada Collective , has made more than $100,000 in less than two months simply by threatening to launch DDoS attack on websites, but never actually launched a single attack. A group of Cyber Extortionists is sending threatening emails to businesses across the globe involves the launching of powerful distributed denial-of-service (DDoS) attacks against victim's website unless a ransom is paid. But, the group never actually launched a single DDoS attack. In a typical scenario, attackers disrupt a targeted website with a short-term DDoS attack in order to demonstrate its power, followed by an e-mail containing ransom note threatening further disruption, if the ransom does not get paid. Armada Collective is the same criminal gang that was responsible for one of largest DDoS attacks against ProtonMail in November 2015 and ext

April 25, 2014Mohit Kumar
Reading a 'Note' created by anyone on the Facebook could trick you automatically to do malicious attacks against others unknowingly. A Security researcher Chaman Thapa, also known as chr13 claims that the flaw resides in 'Notes' section of the most popular social networking site - Facebook, that could allow anyone to launch the distributed denial-of-service (DDoS) attack of more than 800 Mbps Bandwidth on any website. A Distributed Denial-of-Service (DDoS) attack is one in which multiple compromised systems attacks a single target system or service to make it unavailable to its intended users. The flood of incoming requests essentially forces the target system or service to shut down, thereby denying service to the system to its legitimate users. While demonstrating the vulnerability on his blog , he explained that Facebook allows its users to include tags inside the post in order to draft a note with beautiful related images from any source.

Sony PlayStation Network Taken Down By DDoS Attack

Sony PlayStation Network Taken Down By DDoS Attack

August 25, 2014Wang Wei
It's been a bad weekend for Sony Playstation. The entire PlayStation Network was down much of the day after a dedicated distributed denial-of-service (DDoS) attack by online attackers, which left the network inaccessible to users. It's possible that EVE Online and Guild Wars 2 have also been hit by the attackers. Developers on the EVE Online forums have announced DDoS issues, and many users on the Guild Wars 2 forums have been reporting login issues. Sony's PlayStation Network is an online service that connects PlayStation 3 and PlayStation 4 video game consoles to the Internet and to over-the-top video services such as Netflix. What's weird about this attack is that it also includes a security threat against the American Airlines plane in which the President of Sony Online Entertainment, John Smedley, was traveling today. The aircraft along with a full load of passengers was diverted to Phoenix due to a bomb threat. WHO BRING DOWN SONY PLAYSTATION NETWORK? Tw
