This article describes the PHP cross-station attack principle and prevention techniques. Share to everyone for your reference. The specific methods are analyzed as follows: When a cross-site attack is made using some details or bugs in the program, how can we prevent a cross station attack? Here is an example to preve

This vulnerability is caused by a vulnerability that is directly put into the src attribute of the img label without checking the validity of the network image. Currently, most websites on the Internet use similar methods to process network images. The post mainly uses discuz as an example. Currently, all discuz versions are affected. I won't tell you that freebuf can do the same! Discus does not verify the validity of the network image when process

1. Tear Drop attack: The modified IP packet is sent to the destination host, the length of the IP header is negative, the packet length is treated as unsigned integer, and the system attempts to replicate the extremely long packet, which may crash or restart Detailed For some large IP packets, it is often necessary to split the transmission, this is to meet the link layer of the MTU (maximum transmission unit) requirements. For

Code is the best language. The code is as follows Copy Code #demo for Prevent CSRF /*** ENC*/function Encrypt ($token _time) {return MD5 ('!@##$@$$#%43′. $token _time);} $token _time = time ();$token = Encrypt ($token _time);$expire _time = 10; if ($_post) {$_token_time = $_post[' token_time '];$_token = $_post[' token ']; if ((Time () –$_token_time) > $expire _time) {echo "Expired token";echo "} Echo $_token;echo "$_token

absolutely safe. For the X-Treasure password control, as long as an inline hook can be completely broken.Principle: Go to the browser's process memory space, Inline Hook live user32! setwindowshookexw/a function, analyze the parameters of the function, judge if the incoming module belongs to the target module and the hook type is a low-level keyboard hook, then call the original function, wait for the original function to return successfully, then call the original function set a low-level keyb

This article mainly introduces to you about ANGULARJS user input dynamic template XSS attack related data, the text through the sample code introduced in very detailed, for everyone to learn or use Angularjs has a certain reference learning value, the need for friends to learn together. Overview XSS attack is one of the most common attack methods in Web

CC Attack Reason The principle of the CC attack is that the attacker controls some hosts to keep sending a large number of packets to the other server, causing the server to run out of resources until downtime crashes. CC is primarily used to attack pages, everyone has this experience: when a Web page visits a very large number of times, open the page is slow, C

0. Here is an attack code written using this principle: This code took nearly 88 seconds on my VPS (single cpu,512m memory), and CPU resources were almost exhausted during this time: A common hash table of the same size is inserted for only 0.036 seconds: It can be shown that the second code inserts n elements at an O (n) level, while the first attack code takes O (n^2)

PHP Prevent injection attack case analysis, PHP injection Example analysis In this paper, the method of preventing injection attack by PHP is analyzed in detail. Share to everyone for your reference. The specific analysis is as follows: PHP addslashes () function --single apostrophe plus slash escape PHP String function Definition and usage The Addslashes () fun

Shen is a very practical tactic, ancient and modern, many military strategists, politicians, entrepreneurs are talking about this tactic, in the network attack and defense is no exception, system administrators will use such tactics. Because each network system has a security vulnerability, if it is of high value, these vulnerabilities can be exploited by intruders. Usually, people will take the initiative to make up for these vulnerabilities or flaws

Next we will take the release version as an example to illustrate the anatomy. The key code for the EXE disassembly is as follows: Function showcomputername:00401030: 8B 4C 24 04 mov ECx, dword ptr [esp + 4] 00401034: 83 EC 0C sub ESP, 0ch 00401037: 8d 44 24 00 Lea eax, [esp] 0040103b: 50 push eax 0040103c: 51 push ECx 0040103d: E8 be FF call 00401000 00401042: 83 C4 14 add ESP, 14 h 00401045: C3 RET Main function:00401080: 68 30 50 40 00 push 405030

Transferred from: http://www.lijiejie.com/openssl-heartbleed-attack/　　The openness and prevalence of the OpenSSL Heartbleed vulnerability has excited a lot of people and made others panic. From the point of view of attack, I already know that the online scanning tools are: 1. Nmap Script SSL-HEARTBLEED.NSE:HTTP://NMAP.ORG/NSEDOC/SCRIPTS/SSL-HEARTBLEED.HTMLNMAP-SV--script=ssl-heartbleed 　　OpenSSL Heartbleed

STACK1 calls the stack structure of the F function as shown in:Copy the data to the BUF, and the results are as follows:When 0xffffd710 covers the position of the original EIP, the F function will bounce the 0xffffd710 out to the EIP when it returns, and the program is looking for the following program according to the EIP address.SummaryThis section describes the principle of buffer overflow vulnerability attacks, mainly modifying the value of EIP in the stack.Reference:http://blog.csdn.net/li

This article mainly introduces the example of ARP attack code written in python. For more information, see Note: to use this script, you need to install the scapy package. It is best to use it on the linux platform, because the scapy package always has various problems when installed on windows. The code is as follows: # Coding: UTF-8# Example: sudo python arp
