The Evolution Of Ddos Attacks And Their Impact On Web Security

Due to constant innovation in the threat landscape, modern distributed denial-of-service (DDoS) attacks are almost impossible to detect compared to 12, 10, or even 5 years ago. Protecting against rapidly changing attack vectors and record-breaking attacks is critical to protecting online infrastructure, but can be a daunting challenge for security teams that lack the appropriate resources, expertise or technology.

Yottabyte Ddos Attack

Figure 1 describes the activity of more than 50 attack vectors over the past decade and outlines the increasing sophistication of DDoS.

1. Vector persistence awards are given to: UDP flooding, SYN flooding, and UDP fragmentation, techniques that have been around since Prolexic’s inception for their simplicity and reliability (Figure 2). They are still powerful, often with other carriers.

2. Some important vectors are now obsolete: ICMP floods are popular as easily accessible DDoS vectors, but are much less powerful than other vectors that allow amplification and reflection (Figure 3). Our largest pure ICMP attack to date was only 28 Gbps. These pings can increase, but the average speed of ICMP attacks is only 1.5 Gbps, which is hardly a small flow today, and they are almost exclusively used in combination with other vectors. All ICMP attacks have, on average, two additional vectors.

Denial Of Service Attack

3. Other attacks surfaced and attracted attention, but ultimately failed. The number of CharZen attacks and SSDP floods increased from 2015 to 2018, but are rarely seen today. This may be due in part to better reflectors available and fewer exposed servers using these exploitable protocols.

4. Additionally, CLDAP reflection use emerged in late 2016 and peaked as a top five vector in 2018, but has declined due to improvements in filtering practices, decline in novel reflectors, and attackers’ interest in new, more cost-effective carriers. Due to profit (Figure 4).

From these four pieces of information, it is clear that the threat of DDoS is evolving rapidly. As shown in Figure 5, the top five vectors were responsible for 90% of all attacks in 2010, whereas today the top five vectors are responsible for only 55% of all attacks. This change highlights not only the increasing sophistication of modern DDoS toolkits, but also the intense pressure placed on security teams to defend against a growing arsenal of threats.

History Shows Ddos Volumes To Keep Rising Despite Mitigation Efforts

In both biology and business, whatever works best – whether it’s an adaptable physical characteristic or an effective product strategy – will survive and spread. Similarly, attack vectors that produce maximum impact at minimum cost are likely to grow in popularity and outcompete similar attack vectors. Attackers are constantly looking for new tools to maximize damage and increase cost efficiency.

In the first half of 2022, we got a glimpse of where DDoS was evolving when two dangerous new vectors attacked our platforms for the first time. One has a 65-fold amplification capability, the other 4.2 billion times. So, what factors will ultimately determine the popularity and survival of these new attack vectors?

We don’t know if any of the above vectors will top out or reach new highs. We can be sure that the evolutionary path will continue and the next generation of threats will emerge on the network.

History Of Destructive Cyberattacks

Constant innovation in the DDoS threat landscape keeps organizations aware of ongoing risks and emphasizes the need for uncompromising protection against the latest attacks. To reduce the risk of DDoS-related downtime and avoid bad actors, consider doing the following:

If you are currently under DDoS attack or ransomware threat, call the DDoS hotline at 1-877-425-2624 for immediate assistance, or click here to sign up for a custom threat briefing. History will repeat itself. The History of DDoS and DoS The history of how an attack vector from 1997 re-emerged in a “new” form in 2007, and again in a “never seen before” form in 2017. The history of DDoS and DoS is a living document and a recording tool (look for updates). Don’t focus on the “biggest” or most “destructive” DDoS attacks. The focus is on the attack vectors and what the industry does to respond to attacks (even if the response is zero). “History of DDoS and DoS” Makes no sensational claims about “scale”. Size doesn’t matter. What matters is whether the DDoS attack was successful.

Denial of service (DoS) attacks, incidents, and incidents have existed in the Internet community since the early days of the ARPANET. They all occurred on early public networks (Fidonet, BBS networks, Bitnet, etc.) and were part of “mainframe” timesharing culture (people locking each other out of terminals to get more machine time).

Biggest Denial Of Service Attacks In History

Some people think that DoS attacks are new. they are not. Some people believe that just because DoS attacks are not in the news, they “disappear”. The reality is that we will always face DoS attacks. They will be with us as long as we have global interconnectedness of people, machines, AI, and things.

DoS attacks and “distributed DoS” attacks (DDoS) are caused by humans. Behind all intentional and unintentional DoS attacks are humans. The reasons vary but can be divided into five motivations:

Mains Re DoS. The human body is a criminal activity. These DoS attacks are the most common and range from paying people to DoS companies during major events, taking out competing gamers, “ransomware payment motive”, “DDoS extortion”, to intervening in other criminal intrusions/data leaks. Distractions etc. are included. , The key to all these “DoS flavors” is that there are human motivations that society deems illegitimate.

Protest, politics and ideological passion DoS. The second most common DoS attacks are launched by people who are protesting, politically involved, or using DoS as a statement to put forward “principles”. People coming together to ban all whaling is an example of a DoS protest. Students across China are launching DoS tools against Japan’s National Board of Education, and protesting that the “new official history” is a DoS protest. One thing to remember when countering DoS is the side effects it can have on the Internet. In the past, this meant slow internet speeds. Today, protests against DoS can have an impact on hospitals, voice connectivity and other critical infrastructure.

Nation-state actors, state-controlled influence operations, and terrorist DoS. Nation-state threat actors launching DoS attacks are obvious but often overlooked. The Internet is an international battlefield. Struggling countries can and will use the Internet as part of their struggles. Internet conflict planning between these countries will be part of the DoS resilience plan. However, more often “national interest” denial of service will be initiated indirectly through influence campaigns or terrorists. The 2006 attacks in Estonia are a prime example of state actors using “influential people” to serve Estonian interests.

Business competition. Companies compete. In some places there is a clear understanding of how to conduct business transparently and fairly. But this is so only in some parts of the world. Other parties may “delegate” DoS to rival companies to embarrass their competitors at events. Yes, it has some Cyberpunk/Shadowrun/Necromancer implications, but it shouldn’t be dismissed as human DoS inspiration.

Oops – unintentional mistake. The fifth motive is not really a motive, just a result. Some of the more serious DoS incidents are not intentional, but the result. The Morris worm is an example of a system that was not designed to target an Internet-wide DoS system. Slammer is also considered a bug (an insect that looks like a test but is loose). No matter how we respond to DoS incidents, we must remember that humans sometimes make mistakes that have consequences. Don’t fall into the “imagination failure.”

There are many reasons why people launch DDoS attacks. Some of these reasons are not obvious or are part of a larger strategy.

Every month some vendor, operator, or new site talks about one of the biggest, worst, worst DoS attacks. The new claims will be, “New DDoS trends” and “The future of DoS”. A warning “DoS will get worse” will appear and you better do something about it. Most of them are misogynists, boasting about “who is the biggest victim”. There is no point in constantly informing the world about the ever-increasing potential for DDoS to cause harm. This means the cost of building a DDoS resilient infrastructure capable of sustaining your business will continue to increase. However, these reports can be useful if you understand their limitations.
