botnet attack

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

For:-XSS (Cross site script, multi-site scripting attack) is an attack that injects malicious script into a Web page to execute malicious script in the user's browser when the user browses the Web page. There are two types of cross-site scripting attacks: A reflective attack that convinces a user to click on a link that embeds a malicious script to reach the targ

Anti-DDoS (distributed denial of service) attack system is to maintain the stability of the business system, continuous operation and high availability of network bandwidth to provide protection capabilities. However, since the 1999 Yahoo, ebay and other e-commerce sites were attacked by denial of service, DDoS has become a new security threat on the internet, which is very dangerous and very difficult to protect.

Deploy the site to run monitoring equipment, strengthen the Web page horse, access redirection mechanism and domain name resolution monitoring, cut off the main infection path of malicious code. The use of the sandbox technology and a variety of shelling techn

other traffic attacks, or similar to TCP Flood, CC and other ways, and then look for a relatively effective response strategy. There are several approaches to this attack:1). Use "Honey net" protection to enhance the first time analysis and response to attack tools and malicious samples. Large-scale deployment of honey network devices to track botnet dynamics an

The DDoS full name is distributed denial of service (distributed denial-of-service attack), and many Dos attack sources attack a single server to form a DDoS attack, which dates back to 1996 initially and began to occur frequently in China in 2002, 2003 has begun to take shape.Introduction to DDoS Attacks:There are man

ICMP flood attack in Linux programming and linuxicmp Flood AttackIn my previous article "PING implementation in Linux programming", I used the ICMP protocol to implement the PING program. In addition to implementing such a PING program, what other unknown or interesting uses does ICMP have? Here I will introduce ICMP, another famous black technology: ICMP flood attack. ICMP flood attacks are one of the most

SQL injection, XSS attack, CSRF attack SQL injection what is SQL injectionSQL injection, as the name implies, is an attack by injecting a SQL command, or rather an attacker inserting a SQL command into a Web form or a query string that requests parameters to submit to the server, allowing the server to execute a malicious SQL command written.For Web developers, S

"Network attack and defense technology and practice" 11th Week operation SQL injection attack and Practice 1. Research on the principle of buffer overflow, at least for two kinds of database to study the buffer overflow principle?? Inside the computer, the input data is usually stored in a temporary space, the temporary storage space is called a buffer, the length of the buffer has been pre-defined by the p

PHP Common Vulnerability Attack analysis, PHP vulnerability attack Summary: PHP program is not impregnable, with the extensive use of PHP, some hackers are also in the absence of the trouble to find PHP, through the PHP program vulnerability to attack is one of them. In the section, we will analyze the security of PHP from the aspects of global variables, remote

The level of automation of attack tools continues to increase. The four phases involved in an automated attack have changed.1. scan for potential victims. A large number of scanning activities have been occurring since the 1997 year. New scanning tools are now using more advanced scanning techniques to become more powerful and speed-increasing. 2. intrusion into a vulnerable system. Previously, attacks on

The CC attack (Challenge Collapsar) is a DDoS (distributed denial of service) and is a common site attack method, the attacker through the proxy server or broiler to the victim host constantly send a large number of packets, causing the other server resources exhausted, until the crash.The CC attack (Challenge Collapsar) is a DDoS (distributed denial of service)

Today, the scanner mistakenly reported the flaw, I think it is a false alarm.Take the opportunity to understand, as if for the NoSQL and Nodejs service side, I think it may be JS for Nodejs is executable code, that is, arbitrary code execution, such an attack.There's a http://stackoverflow.com/questions/27879131/server-side-javascript-code-injection-attack on StackOverflow.Coincidentally, it seems that I and he used the same scan tool, with the same p

, and the attacker can forge the source IP address in the package so that the attacker is not blocked by the packets returned by the server. As you can see, this is a fairly serious issue in the TCP/IP protocol. Filtering packets through a firewall policy can prevent DDOS attacks to some extent.At the moment, the CC attack is mainly for the WEB application to compare the consumption of resources where the crazy request, for example, the search functio

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

Recently, on DEF CON 2018, a prestigious event in the field of global security, GeekPwn Las Vegas Station held the CAAD CTF Invitational, and six teams of top AI scholars and research institutes from home and abroad explored the CTF with a view to combating training as a means of attack.

Docker Web security experts have discovered a new IoT zombie network that uses Linux.proxym malware and is trying to attack the site. Linux.proxym is a Linux malware that creates a proxy network on infected devices through a SOCKS proxy server that forwards malicious traffic and masks its true origins. According to Dr. Web, Linux.proxym was first discovered in February this year, its activities peaked in late May, and the number of devices infecting
