Recently, the number of reflective DDoS attacks using memcached servers has increased significantly. CNCERT has carried out centralized monitoring and analysis on three types of key reflective attacks. This report is a special analysis report on reflective attack resources in February 2018. Focusing on the problem of Internet environment threat management, this paper focuses on the analysis of "what are the important network resources used to launch DDoS reflection attacks". Network resources for reflection attacks include:

SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.
I like what Sister Ping said: "I like to do one thing instead of insisting on doing one thing." Many people say that one must stick to it. If it grows in your blood and is as natural as eating and sleeping, it does not need to "stick to it" and just do it. Saying "stick to" is because you don't love enough, so you need to remind yourself all the time.
In fact, we also need to pay attention to one thing, Because when a packet passes through a chain, All the rules of the current chain are matched, However, there must always be an order when matching. We should match one by one, and we said that rules of the same functional type will gather in a "table". Then, which rules in the "table" will be executed at the front of the "chain"? At this time, there needs to be a priority problem. We also take prerouting "chain" as an illustration.

One is a vulnerability against TCP/IP. The last is to try and carry out real violent attacks.
The verification code changes when recording, so if you want to use BurpSuite for replay attacks, you need to find a login website that does not need the verification code. 2.2. 2 During the experiment, first of all, according to the above analysis of replay attacks, I chose Touniu Net for the experiment. You can see that its login page does not need to enter a verification code. Then log in, And open BurpSuite to observe the intercepted login information, Forward the unwanted response in the past, Find the important information part, and the intercepted content is shown in the following figure: the circled part is my login name and encrypted password. Record the information to carry out replay attack. When accessing the login page again, only the request needs to be released again to achieve the login effect, without inputting the user name and password. The way to replay the attack is as follows, Choose Block Login Info. Right-click SendtoRepeater for a replay attack, Then enter the Repeater tab to observe, You can see that the content of the attack that you will replay appears in the request interface. Stand-alone go makes replay attacks, The return information of the page appears in the response interface, It represents the success of login authentication, as shown in the following figure: Let's modify the login information just recorded and replay it again to see how the results will be different. Here, I have deleted several digits from the user name, so the login will fail. Through the Compare tab, we can compare the page response after two logins.
Other methods to modify rules: delete rules by number first, and then add a rule at the original number position.
