DDoS-attacks have become cheaper, shorter and more powerful

DDoS-attacks are getting bigger, but their duration is falling, according to a recent report of the company Arbor Networks, which provides commercial services for protection from DDoS-attacks. According to the company, for the first six months of 2013 the average capacity of DDoS-attacks remained unchanged 2 Gbit / s. Analysts say that such a trend was recorded for the first time since before the power is always growing. However, in Arbor say that on the average the rules there are exceptions. For example, anti-spam service Spamhaus experienced in March of this year, the attack power of 300 Gbit / s. The report Arbor says that the soup-like attacks also recently become frequent and are no longer uncommon. For example, from January to June 2013 the average power "super attack" was the order of 20 Gbit / s - more than double the figure of the same period in 2012. Earlier, the trend for the occurrence of the so-called super-DDoS-attacks and talking company Akamai Technologies, the world's largest operator of content delivery networks. In Akamai said that the nature of the super-DDoS explained simply - rent small botnets to launch attacks is becoming easier and the presence of a particular financial resource attackers at hand may be dozens of networks. So, rent a small botnet can now only $ 20 per hour. How Akamai, and Arbor say that the strategy of collecting small botnets used before hackers group QCF (Izz ad-Dim al-Qassam Cyber ​​Fighters) - they ran the short-lived but very powerful attacks on popular resources on the network. Arbor report also says that the very business model for renting a botnet has become a profitable business for operators of such resources. The company notes that there are cases of "zero downtime" botnets, botnets when the power for 10-20 minutes switched to attack one resource to another. Monitors company registered as the waves of attacks with a boat-segment switched to a completely different resources. "In general, the attacks become more, as a large share of resources going into the hands of one or a couple of operators to get their hands botnet is now easier than ever either. On the other hand in the arsenal of protection from DDoS-attacks is also becoming more and more vehicles, "- said in Arbor. cases of exotic attacks company observes major attack on DNS-servers, as well as the creation of dummy DNS-resolvers to victim computers were connected to them and directed to sites with malicious software. At Arbor say that the practical side of attacks on DNS-servers, they are not too clear, since the only thing that they receive the organizers of attacks - this is a temporary paralysis of some of the client machines, but it does not affect the operation of other servers. "We can say that the organizers of the attacks and defender of them play cat-and-mouse. We improved filtering, hackers have expanded the scope of addresses, we began to switch customers to the alternative route, the hackers have reduced the duration of attacks. And so on, "- told the Arbor.
