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).

Defense Against CC attacks
Discuz! 5.5 based on the past anti-CC attack, two methods are added. You can combine appropriate methods based on the actual attack situation. I will briefly describe the configuration method, but will not elaborate on the confrontation principle in detail.

. 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
This article summarizes some of the strange cc control servers I've seen in my safe work. The design method of the controller server and the corresponding detection method, in each Cc Control service first introduces the Black Hat part is the CC server design method for the different purposes, and then introduces the white hat part is related detection methods , let's have a look at the western set. There's a part of the white hat part of the detection method that requires some data and statisti
In the event of a DDOS Denial-of-Service attack on a website, the second step is to determine the type of DDOS attack in the methods used by EeSafe to help the website solve the problem.

By March, the site incredibly to the second home page Baidu, although only persisted for three days, immediately fell to the fifth, but those days every day has 100,000 IP, at that time cut a map (with the plug-in of shielding ads, so no promotional links).

By analyzing the data of 50 million fake Google crawlers, incapsula found that up to 34.3% of counterfeit crawlers are malicious, of which 23.5% are used for layer-7 DDoS attacks.
Anti-DDoS attacks initiated by Google crawlers make it very difficult for website operators: they either shield all Google crawlers, disappear from search engines, or
Counterfeit Google crawlers have become the third-largest DDoS attack tool
In the article Prolexic released the first quarter of 2014 Global DDoS attack report published by quickshield, we learned that the attack traffic initiated by the "Reflection amplification" technology
