One third of all websites may be under the DoS attack at any time

Houston, we have a problem! A serious problem that theoretically can affect one-third of all websites on the Internet. Recently Israeli security researcher Barak Tawily found a WordPress vulnerability that can lead to a massive DoS attack. DoS attack is a type of cyber-attack when an attacker drains network or server resources by flooding it with an enormous amount of requests. Every request needs some resources, but if you’re capable of making a lot of these requests or you find a way to drain more resources with fewer requests you’ll finally make the network or server inaccessible for the time of the attack.

Do not confuse DoS attacks with DDoS attacks, DoS (denial-of-service attack) attacks run from a single source of requests and DDoS (distributed denial-of-service attack) need more than one request sources. In this case, we are talking about attacks that are possible to execute from a single request source (for example one computer). The success of a DoS attack is directly dependent on how many requests a hacker can generate and how much it consumes server or network resources. Usually, DDoS attacks are more efficient than DoS attacks. But in this case, a single attacker could make a significant load on the server and create the real denial-of-service situation.
