The attack also reached 110 million packets per second On June 14, a Chinese gambling company was unlucky enough to be at the end of a complex multi-vector DDoS attack that blasted over 470 gigabits per second (Gbps) and over 110 million packets per second (Mpps) at its servers. The attack came after the company had already faced multiple 250+ Gbps attacks in the previous days. The good news is that this 470 Gbps attack only lasted four hours and was deflected by the company’s DDoS mitigation service. Nine-vector DDoS attacks are rare Even if short, the attack itself was extremely complex, with the crooks utilizing nine different attack vectors. Compared to data from the first quarter of 2016, nine-vector DDoS attacks are extremely rare and happen once every 500 attacks (0.2% of all attacks). This particular attack started with a basic network-level assault that wanted to suffocate the network with large amounts of data. It first blasted SYN payloads, then generic TCP and UDP data packets. From the get-go, the attack was different from all the previous attacks, throwing over 300 Gbps at its target from its initial seconds, before growing bigger to reach its peak value. Attack evolved from network to application level Midway through the attack, the crooks completely changed tactics. They stopped the network-level attack and shifted to an application layer DDoS, during which attackers send packets of a smaller size, but in larger numbers to occupy the memory of the receiving servers. Incapsula, the company that was providing DDoS mitigation, said that in Q1 2016, it regularly mitigated application layer 50+ Mpps DDoS attacks every four days, and 80+ Mpps attacks every eight days. Even if this attack exceeded 110 Mpps, the company was able to mitigate the threat. The combination of all these vectors makes this one of the most complex attacks the company saw. In fact, Incapsula said this was the biggest DDoS attack it mitigated in terms of sheer size (470 Gbps) in its entire history. “On a technical level we want to make clear that there isn’t much difference in mitigating 300, 400, or 500 Gbps network layer attacks,” Incapsula’s Igal Zeifman and Ofer Gayer explain. “They’re similar threats, each dealt with in a similar manner. Large attack waves aren’t more dangerous than smaller ones. All you need is a bigger boat.” Source: http://news.softpedia.com/news/chinese-gambling-company-was-target-of-a-nine-vector-470-gbps-ddos-attack-505850.shtml#ixzz4D57R4eWd

The Network Ops DDoS Playbook
A DDoS attack against a jewelry shop website has lead researchers to the discovery of a CCTV botnet comprised of some 25,000 cameras from around the globe. The website had been repeatedly attacked, first with 35,000 HTTP requests per second and then, when those efforts were thwarted, with 50,000 HTTP requests per second. Looking into the IP addresses from which the attack was coming from, Sucuri researchers discovered that all of them were running the … More ?

25,000-strong CCTV botnet used for crippling DDoS attacks
All clues lead back to Chinese DVR vendor TVT A botnet of over 25,000 bots lies at the heart of recent DDoS attacks that are ferociously targeting business around the world. More exactly, we’re talking about massive Layer 7 DDoS attacks that are overwhelming Web servers, occupying their resources and eventually crashing websites. US-based security vendor Sucuri discovered this botnet, very active in the last few weeks, and they say it’s mainly composed of compromised CCTV systems from around the world. Their first meeting with the botnet came when a jewelry shop that was facing a prolonged DDoS attack opted to move their website behind Sucuri’s main product, its WAF (Web Application Firewall). Botnet can crank out attacks of 50,000 HTTP requests per second Sucuri thought they had this one covered, just as other cases where companies that move their sites behind their WAF block the attacks, and eventually the attacker moves on to other targets. Instead, they were in for a surprise. While the initial attack was a Layer 7 DDoS with over 35,000 HTTP requests per second hitting the server and occupying its memory with garbage traffic, as soon as the attackers saw the company upgrade their website, they quickly ramped up the attack to 50,000 requests. For Layer 7 attacks, this is an extraordinarily large number, enough to drive any server into the ground. But this wasn’t it. The attackers continued their assault at this high level for days. Botnet’s nature allowed attacks to carry out attacks at higher volumes Usually, DDoS attacks flutter as the bots come online or go offline. The fact that attackers sustained this high level meant their bots were always active, always online. Sucuri’s research into the incident discovered over 25,513 unique IP addresses from where the attacks came. Some of these were IPv6 addresses. The IPs were spread all over the world, and they weren’t originating from malware-infected PCs, but from CCTV systems. Taiwan accounted for a quarter of all compromised IPs, followed by the US, Indonesia, Mexico, and Malaysia. In total, the compromised CCTV systems were located in 105 countries. Top 10 locations of botnet’s IPs The unpatched TVT firmware comes back to haunt us all Of these IPs, 46 percent were assigned to CCTV systems running on the obscure and generic H.264 DVR brand. Other compromised systems were ProvisionISR, Qsee, QuesTek, TechnoMate, LCT CCTV, Capture CCTV, Elvox, Novus, or MagTec CCTV. Sucuri says that all these devices might be linked to Rotem Kerner’s investigation, which discovered a backdoor in the firmware of 70 different CCTV DVR vendors . These companies had bought unbranded DVRs from Chinese firm TVT. When informed of the firmware issues, TVT ignored the researcher, and the issues were never fixed, leading to crooks creating this huge botnet. This is not the first CCTV-based botnet used for DDoS attacks. Incapsula detected a similar botnet last October. The botnet they discovered was far smaller, made up of only 900 bots .

Inside the World of the Dark DDoS
One of the most concerning characteristics of the Godless malware is the ability to receive remote instructions on which app to download and install on mobile devices, without the user’s knowledge. This is called command and control (C&C). Being a DDoS subject matter expert, I believe this has the makings of something more insidious than malicious ads. Nearly one million infected Android devices connected to 4G LTE networks offers some serious firepower for a botnet … More ?
The central banks of Indonesia and South Korea are reportedly bulking up security on their public-facing websites after being hit with cyberattacks and distributed-denial-of-service (DDoS) disturbances linked to notorious hacking collective Anonymous. In response to the attempted cyberattacks, Ronald Waas, deputy governor of Bank Indonesia (BI), told Reuters his institution was forced to block 149 regions that don’t usually access its website, including “several small African countries”. The central banks of Indonesia and South Korea are reportedly bulking up security on their public-facing websites after being hit with cyberattacks and distributed-denial-of-service (DDoS) disturbances linked to notorious hacking collective Anonymous. In response to the attempted cyberattacks, Ronald Waas, deputy governor of Bank Indonesia (BI), told Reuters his institution was forced to block 149 regions that don’t usually access its website, including “several small African countries”. As previously reported, a video statement posted to YouTube on 4 May by the group said: “We will not let the banks win, we will be attacking the banks with one of the most massive attacks ever seen in the history of Anonymous.” Later, the central bank of Greece admitted its website was taken offline for a short period of time. This was followed by other banks in countries including France, England, Scotland and Sweden. In June, the hackers announced that ‘phase three’ of the operation has started – dubbed Project Mayhem – and that the focus of the campaign would change to include major stock exchanges. In any case, the global banking system has been left shaken by a number of successful hacks, breaches and cyber-heists throughout 2016. In one attack, the Bangladesh central bank was targeted by a highly coordinated team of hackers that were able to steal a massive £81m via fraudulent money transfers.

The official English language website of Muslim Brotherhood movement was forced to go offline after facing massive DDoS attacks! Earlier today, a hacker going by the handle of SkyNetCentral conducted a series of distributed denial-of-service (DDoS) attack on the official website of Society of the Muslim Brothers or Muslim Brotherhood (Al-Ikhwan al-Muslimun in Arabic) forcing the website to go offline despite using CloudFlare DDoS protection service. The hacker also conducted DDoS attacks on the official website of Freedom and Justice Party, which is an Egyptian political party affiliated with Muslim Brotherhood. That’s not all, the attacker also managed to bypass site’s security and steal Al-Ikhwan al-Muslimun’s files from the database, ending up leaking it online for public access. Upon scanning the leaked data HackRead found it to be legit and never been leaked on the internet before. The data dump contains IP addresses, email conversation, comments and commenters’ names and IP addresses. It seems as if the hacker only managed to compromise some tables of the database without getting hold of any sensitive data. The only damage that can be caused is tracing the location of the commenters but that’s not a task just anyone can perform. Here is a screenshot from the leaked data showing comments and IP addresses: At the moment, the motive behind these attacks is unclear however after going through attacker’s profile it’s evident that they have been targeting Muslim Brotherhood, Council on American-Islamic Relations – CAIR and other similar organizations.

We have all heard the stories of businesses which have suffered debilitating DDoS attacks and, in some cases, succumbing altogether. Take Code Spaces, the web-based SVN and Git hosting provider which suffered such an attack in June 2014 that it was forced to wave the white flag and cease trading after recovering all the data lost would cost too much. Now, a new piece of research from A10 Networks argues businesses face ‘sudden death’ from DDoS if caught unawares. The average company was hit by an average of 15 DDoS attacks per year, according to the survey of 120 IT decision makers, with larger organisations more badly affected. One in three (33%) respondents said they had encountered DDoS attacks of more than 40 Gbps, while one in five had suffered downtimes of more than 36 hours due to the attack. The average attack of those polled lasted 17 hours. More than half (54%) of respondents said they would increase their DDoS budgets in the coming six months, while multi-vector attacks were seen by the majority of those polled (77%) as the most dangerous form of DDoS threat in the future. “DDoS attacks are called ‘sudden death’ for good reason. If left unaddressed, the costs will include business, time to service restoration and a decline in customer satisfaction,” said A10 Networks CTO Raj Jalan. He added: “The good news is our findings show that security teams are making DDoS prevention a top priority. With a better threat prevention system, they can turn an urgent business threat into an FYI-level notification.” Previous research has examined the growing sophistication of DDoS threats. In April, Neustar argued that such DDoS issues were “unrelenting”, with more than seven in 10 global brands polled having been subject to an attack.
