Scapy is a powerful interactive packet processor written by Python that can be used to send, sniff, parse, and forge network packets, often used in network attacks and tests. This is done directly with Python's scapy. Here is the ARP attack way, you can make ARP attack. Copy Code code as follows: #!/usr/bin/python """ ARP attack """ Imp

File Upload is a common feature of WEB applications. It is a normal business requirement and has no problems. However, if the file is not correctly processed during uploads, security problems may occur. This article analyzes the File Upload detection methods and how to bypass the corresponding detection methods in detail, and provides a security protection method for file upload attacks. The file upload attack means that attackers can use WEB applicat

Tags: pppoe session attackPppoe sessions are divided into discovery and session phases. We have implemented the pppoe session before the attack in the discovery phase. The problem arises: In the session phase, we impersonate a server and establish a complete discovery phase with the client, in addition, suitable NCP negotiation in the session phase is provided. When the password is verified, the client sends the plaintext password. Can you obtain the

An attacker could make a Dos attack through a replication node or generate an illegal XML that would cause server-side logic to break. An attacker can also manipulate external entities, causing any file or TCP connection ports to open. Poisoning with the definition of XML data can also cause changes in the running process to help attackers gain confidential information. 1. Cross-site scripting attacks in Ajax example, the Yamanner worm exploited the

... Previous Stack parameter 1 The address to which the previous stack was run Start address of previous stack Parameter n ... Parameter 1 After 3, you can see that the whole function exits, and the stack pointer goes back to the stack of the calling function. This completes the complete function call, and also completes the stack-in

Reason PHP script part of the source code: Copy the Code code as follows: $fp = Fsockopen ("udp://$ip", $rand, $errno, $ERRSTR, 5);if ($fp) {Fwrite ($fp, $out);Fclose ($FP); PHP script in the Fsockopen function, to the external address, through the UDP send a large number of packets, attack each other. Response You can disable the Fsockopen function through php.ini, and use Windows 2003 Security Policy to mask the UDP port on this computer. disabling

First you need to declare. This is purely without foresight and a bit of talent to develop a silly view, only for Web reference systems security.1. HTTP parameter injection attackThe parameters, which are used as a reference in the backend HTTP request, can cause an HTTP parameter injection.A rotten self-thought out, for example:One-to-peer transfer system: money, where to go (from).A very easy system. Developed in order to reuse the code. An inferred character (check) was added. Of course, this

Mobile Game Development Attack and Defense-1. Game Engine selection and mobile game development Attack and Defense Engine Now mobile games fire of a mess, engine is also endless in addition to leading the 3D market Unity3D, Duba 2D market Cocos2D-X, as well as illusory, Sphinx and so on, and even Sohu has developed a domestic Genesis-3D engine. Others are not much, here mainly compare Unity3D and Cocos2D-X,

New Bank Trojan Anubis attack, a collection of ransomware, keyboard recorder, remote Trojan, anubis attack According to PhishLabs, a network security company, in 5th day of this month, they discovered a new variant of the Bank Trojan BankBot, which is being disseminated by disguising it as a legitimate application of Adobe Flash Player, Avito, and HD Video Player. PhishLabs indicates that the new variant na

Attack Android injection "1", attack android "1"PrefaceThis series was originally shared by the company and has a large amount of content. Therefore, we reorganized this PPT into a blog, hoping to help you learn it. I will first use an "text message interception" as an example to throw a problem and propose a "injection"-based technical solution to increase the interception priority. Then I will focus on th

This article illustrates the YII framework's approach to preventing SQL injection, XSS attacks, and csrf attacks. Share to everyone for your reference, specific as follows: The methods commonly used in PHP are: /* Anti-SQL injection, XSS attack (1)/function Actionclean ($str) {$str =trim ($STR); $str =strip_tags ($STR); $str =stripslashes ($STR); $str =addslashes ($STR); $str =rawurldecode ($STR); $str =quotemeta ($STR);

The root cause of SQL injection attacks is the vulnerability of SQL specifications, but because of the long-term existence and use of the specification, it is almost impossible to modify the specification, only from the developer itself to avoid attacks, although the SQL injection is very serious, but now relatively well controlled, here just as a learning content.The test process is as follows:1: Build php,mysql development environment, can see my other blog custom development PHP Environment2:

address of the computer infected with viruses and the physical address of the network card.3. Set ARP tables to avoid the impact of ARP spoofing on trojansThis method can reduce the impact of other computers of the Trojan on the machine to some extent. Use the method described above to determine the correct gateway IP address and gateway physical address, and then enter and execute the following command in the "command prompt" window:ARP-s gateway IP Gateway physical address4. Static ARP bindin

The core switch is currently the most commonly used networking device, and its security performance is also good. However, improper use may also cause some problems. There are blue sky and white clouds on the Internet, there is also a hidden underflow, if you do not pay attention to it, a variety of network viruses may be "not please come ". In the event of a network virus attack on a LAN, the Internet access speed is not normal. In severe cases, the

Attack Android injection "3", attack android "3"I continue to detail the technical solution for Injection through ptrace in "II". In this chapter, I will introduce a unique Injection Technology on Android, named -- Component Injection. As the name suggests, this method is related to Android components.

still released the code, which would allow malicious hackers to exploit it. Microsoft then released a patch in Tuesday to fix the two vulnerabilities, but understandably, the company is dissatisfied with Google's move to disclose details of security breaches, as Microsoft is not only preparing patches but is also about to release them. industry insiders point out that the details of public disclosure of security breaches prior to the release of the patch are only helpful to a very small number
