Everything has two sides. The webpage Trojan creation technique introduced in this article is intended to strengthen everyone's awareness of prevention, rather than thinking about "infected creatures ". We hope to provide some help to you and create a secure Internet access environment. If you visit the xxx website (a portal website in China), you will have a gray pigeon Trojan. This is what a hacker told me. Open the home page of the website. After

C/c ++ Open Course Study Notes-Hacker code analysis and prevention, and wisdom podcast Study Notes Hacker code Analysis and Prevention notes [Course Introduction] C/C ++ language is similar to the underlying computer language except assembly. Currently, mainstream operating systems such as windows, linux, iOS, and Android are all written in C/C ++, therefore, many viruses and Trojans are implemented using

I can't help but claim a topic that everyone is so enthusiastic about. If you can find it, let's briefly talk about the Linux system password attack and prevention. In early Linux systems, the/etc/passwd file contains information of each user in the system. of course, after a user's password passes through a certain number and logic algorithm, I can't help but claim a topic that everyone is eager to claim. If you can find it, let's briefly talk about

recently took a little time to "the King of Destruction-ddos attack and the depth of the prevention of the analysis" to read it, frankly, this book is relatively simple, can be said to be an introductory book, of course, for me this kind of DDoS smattering people, is also a good book, at least I learned something. DDoS is a shorthand for distributed denial-of-service (Distributed denial of service, DDOS), and the name shows that its attack is distribu

Thinkphp is it because of the prevention of XSS that every time you submit content with the editor, some symbols are escaped, which causes the pictures that cannot be edited in the editor to display properly? Always encountered this problem before. At first I thought it was an editor problem, and then I changed the editor or there was a problem. Reply content: Thinkphp is it because of the prevention o

IPS (Intrusion prevention system) and WAF (Web Application Protection system) Two products have different usage scenarios, with the complexity of web application development, security requirements are increasing, the emergence of WAF is in compliance with the needs of the market and technology.Web application protection is undoubtedly a hot topic. Due to the development of technology and people's expectation of convenience, Web application becomes the

the Trojan Horse is mainly: 1) Detection Trojan. 2 to find the Trojan boot file, generally in the registry and the system startup related files can find the location of the Trojan file. 3 Delete the Trojan file and delete the information about the Trojan in the registry or system startup file. But for some very cunning slippery Trojan, these measures are unable to find out, now the means of detection Trojan is nothing but through the network to connect and view system process, in fact, some

How to better achieve the prevention of hacker attacks, I mention personal views! First, the free program does not really have a fee, since you can share the original code, then the attacker can analyze the code. If you pay attention to precautions in detail, your site's security will be greatly improved. Even if there are vulnerabilities such as SQL injection, attackers will not be able to take your site immediately. Because of the ease and ease of
