A large number of WordPress websites are infiltrated and become the source of DDOS attacks Recently, Sucuri security researchers found that tens of thousands of WordPress sites were used for layer-3 DDos attacks. A total of 26,000 different WordPress sites continuously send HTTPS requests to the same website at 10 thousand to eleven thousand times per second, up to 20 thousand times per second. More seriou

In recent days the company's official website and Business System registration page frequently encountered DDoS attacks, resulting in the IIS application pool CPU occupancy rate of 100%, access to the site 503 errors.

Attack | difference For readers: DDoS researcher, major webmaster, network administratorPre-Knowledge: ASP Basic reading abilityMany friends know the barrel theory, the maximum capacity of a bucket of water is not determined by its highest place, but by its lowest place, the server is the same, the security of the server is determined by its weakest point, and the most vulnerable places are more dangerous than the server.

With the gradual integration of mobile terminals and PCs, more and more websites are implementing a policy to ensure the reliability and traffic quality of users, that is, sending mobile phone verification codes to users' mobile phones. At Wooyun, we can often see the bypassing of these things and the abuse of these things-sms dos, which causes great inconvenience to users, vendors are also active in repairing this problem (maybe because China Mobile charges fees based on the number of items).

Use the firewall function of Linux to defend against Network AttacksVM service providers may be attacked by hackers during operation. Common attacks include SYN and DDOS attacks. By changing the IP address, it is possible to find the attacked site to avoid the attack, but the service interruption takes a long time. A thorough solution is to add a hardware firewall. However, hardware firewalls are expensive. You can consider using the firewall function

To combat DDoS (distributed denial of service) attacks, you need to have a clear understanding of what happened during the attack. In short, a DDoS attack can be accomplished by exploiting vulnerabilities on the server, or by consuming resources on the server, such as memory, hard disks, and so on. There are two main types of DDoS attacks: bandwidth exhaustion at

In IDCs, hardware firewalls are usually used to prevent DDOS and CC attacks. IPtables can provide good protection for a small amount of attacks. 1. firewall enabling/disabling in Linux Command 1) permanently effective. it will not be enabled after restart: chkconfigiptableson disabled: chkconfigiptablesoff2) effective immediately, in IDCs, hardware firewalls are usually used to prevent DDOS and CC attacks.

There is a virus in a machine in a LAN. If the virus is not eliminated and isolated in time, other machines will soon be infected with the virus. Once the virus is infected with the whole site machine, the network anti-virus will be disabled, and a large amount of manpower and material resources will be invested in repeated checks; otherwise, the system will be damaged, and Internet cafes will be forced to shut down. Internet cafe owners are talking about viruses. Those who have experience in ma

Another way is to click Start, select Run, enter cmd, pop up the cmd window, type the command: C:\netstat-na, if received a large number of syn_received connection status can be determined to have Synflood a
