ddos attack statistics 2015

In the previous blog (http://cloudapps.blog.51cto.com/3136598/1708539), we described how to use Apache's module Mod_evasive to set up anti-DDoS attacks, in which The main prevention is the HTTP volume attack, but the DDOS attack way, a lot of tools, a random search to know, we look back, what is called Dos/

From the 07 of the Estonian DDoS information war, to this year Guangxi Nanning 30 internet cafes suffered from DDoS ransomware, and then to the Sina network suffered a DDoS attack can not provide external services for more than 500 minutes. DDoS intensified, attacks increase

an attacker builds a site that contains a malicious JS code page, visitors to that site will become participants in the DDoS attack. It is deduced that the greater the number of visits to the Web page, the greater the DDoS traffic. However, because of the limited number of visits to the Web page in general, the destructive power of

simple statistics, we found some 3322 generic malware domains but found that it wasn't what we needed, because only a handful of machines went to it, and after some time we finally found that a domain-access volume was the same as Naver (a Korean portal). Workgroup001.snow****.net, it seems that the management of their own botnet is very good, about 18 machines have access to this domain name, hosting the domain name in Singapore, the Survival time T

February, foreign hacker organizations launched a high-volume DDoS attack on XBOX, one of the world's largest online gaming platforms, which had a business impact for up to 24 hours. In early March, domestic game manufacturers were also under heavy DDoS attacks. It seems that 2016 is destined to be an extraordinary year.After 24 hours of confrontation, the X

1. Defensive base 1.1. How big is the attack flow?When it comes to DDoS defense, the first thing to do is to know how much of an attack has been hit. The problem seems simple, but in fact there are a lot of unknown details in it. In the case of SYN Flood, in order to increase the efficiency of sending SYN wait queues on the server, the IP header and TCP header

. If the TCP serial number of the target system can be pre-calculated, whether the Blind TCP three-time handshakes with pseudo source address can be inserted or not is worth testing! In fact, the experiment I did does not explain anything. I just verified the TCP protocol serial number and the test and calculation functions. I think the author is inspired by the CC attack principle and cannot figure out the proxy method to achieve the CC

High-traffic attacks are growing, with more than hundred g of attacksIn recent years, the United States Federal Communications Commission (FCC) CC on broadband redefined, the downlink speed from 4Mbps to 25Mbps, the uplink speed from 1Mbps to 3Mbps. Internet users around the world have a 2008-2012 annual average growth rate of 12%, 2013 Internet users have surpassed 37.96% of the population, and the number of users is expected to exceed 3 billion in 2015
