Can We End DDoS Attacks With Blockchain Technology?

A DDoS (Distributed Denial of Service) is a type of cyber attack in which websites are rendered unusable because it is flooded with requests from many different devices at the same time. This can do catastrophic damages to business.

What Cyber Criminals Can Get

Cyber criminals, meanwhile, love the opportunities that DDoS attacks give them. In fact, a DDoS attacks can generate multiple sources of income for hackers.

“DDoS attacks are often used as leverage for blackmail. Once a hacking group has a reputation for being able to field a large and dangerous botnet to knock servers offline, they can demand huge ‘protection’ payments from businesses afraid of facing their wrath. In fact, they don’t even have to do the hacking in the first place.”

Technology to Protect Against DdoS Attacks

Unsurprisingly, a lot of technologies are being developed to help businesses avoid DDoS attacks. However, in this cat and mouse game that is played on the internet, any new protection that is put in place will soon get destroyed by hackers. Meanwhile, it is important to note that a DDoS attack has an Achilles heel, which is that it requires a lot of processing power and bandwidth to be able to provide the huge traffic required to bring down a website. A DDoS attack is usually launched from a machine that is controlled through malware, making it nearly impossible to trace. DDoS protection companies open point to this difficulty as a reason for not being able to deliver the protection they promised, just like when Akamai failed to protect the website of Brian Krebs.

“Akamai said so-called “booter” or “stresser” DDoS-for-hire services that sell attacks capable of knocking Web sites offline continue to account for a large portion of the attack traffic in mega attacks. According to Akamai, most of the traffic from those mega attacks in Q3 2016 were thanks to Mirai – the now open-source malware family that was used to coordinate the attack on this site in September and a separate assault against infrastructure provider Dyn in October.”

Emergence of Blockchain Technology

Fortunately, it now seems that there might be a solution to these problems, and that this solution lies in blockchain technology. Blockchain is perhaps best known for running cryptocurrencies and also for creating systems like Ethereum. All of these are said to be almost incorruptible. One company that believes that this type of technology could be used to prevent DDoS attacks is Gladius, which is based in Maryland.

“DDoS attacks are becoming an increasing reality of operating a business with an online presence. These attacks can cost an incredible amount of money, not just in lost uptime, but also a loss in consumer trust and crisis PR. Gladius is the decentralized solution to protecting against DDoS attacks by allowing you to connect to protection pools near you to provide better protection and accelerate your content. With an easy to use interface as well as powerful insight tools, Gladius enables anyone to protect and accelerate their website.”

Gladius, however, is only a startup company, and this means that they will have some significant challenges to overcome. Obviously, it is too early to tell whether their system will ultimately be successful. One of the greatest challenges they will have to overcome, ironically, is making sure that DDoS hackers do not get hold of the machines used to protect against DDoS and use it to stage an attack instead.

As technology advances, both attackers and defenders have to change the way they operate. It is likely that this particular cat and mouse game will be an endless one. For as long as humans have been around, crime has been around as well and this is unlikely to ever change. All that we can try to do is stay ahead of the game.
