XSS cross-site scripting attacks have always been regarded as the most popular attack method in client Web security. Because of the complexity of the Web environment and the variability of XSS cross-site scripting attacks, this type of attacks cannot be completely solved. So what are the specific attack behaviors of XSS cross-site scripting attacks and how can we effectively prevent them? This document anal
Over The years , internet paralysis in several cities in the United States, including Twitter,Shopify,Reddit, and so on, a large number of internet-known websites for hours without normal access. The US Dyn company, which provides domain name resolution services for many websites , says the company has been subjected to massive "denial of service"(DDoS) attacks. in the words of security researchers, it is called Mirai 's malicious files have been exploiting the flaws in "male" products, injecti
many ways to look for hash collisions, such as birthday attacks for general attacks and the modulo difference method. These methods are used to attack the intermediate encounter attacks of hash schemes with a group chain structure, modify group attacks based on Modulo-arithmetic hash functions. Here I will briefly introduce the following four methods for finding a collision:
Equals substrings

1. NTP reflection and amplification attacks, whether based on DNS or NTP, are ultimately based on UDP protocol. In the UDP protocol under normal circumstances, the client sends the request packet to the server side, the server returns the response packet to the client, but the UDP protocol is non-connected, so the client sends the source IP of the request package is easy to forge, when the source IP is modified to the victim's IP, the response packet returned by the end server will return to the
In this article we will explore the theory and demonstration of session hijacking, and discuss related detection and defense techniques. IntroductionIn the previous two articles we discussed the ARP cache poisoning and DNS spoofing separately, as shown in the previous example, we can see that the man-in-the-middle attack is a very effective form of attack and more and more difficult to detect. In this arti
Recently, hashtable collision attacks (HashtablecollisionsasDOSattack) have been raised, and various languages have been involved. This article combines the PHP kernel source code to talk about the principles and implementation of such attacks. For more information, see the following illustration to show you how to explore the PHP kernel: hash table collision attack principles.

Getting Started with XSS attacksXSS represents the Cross site Scripting (span scripting attack), which is similar to a SQL injection attack where SQL statements are used as user input to query/modify/delete data, and in an XSS attack, by inserting a malicious script, Implement control of the user's browser.There are two types of XSS attacks:
Non-persiste
Introduction
Not long ago, I published a blog post on the Raidersec blog about how to use Python and Scapy to bypass authentication attacks. I am very happy to write this article because I have not only learned how to use the aircrack suite, but also have the opportunity to deeply understand the differences in the operating methods of wireless attacks.
Therefore, as mentioned in this Article, this blog article will introduce a series of short and concise blog articles discussing how to use Pytho

Non-authorized access: unauthorized access to related data
Information disclosure or loss: information leaked or lost during transmission
Corrupted data integrity: Data was modified during transmission
Denial of service attack: by sending a large number of packets to the server, consuming the resources of the server, making the server unable to provide services

First, XSSCross Site script attackA malicious attacker inserts malicious script code into a Web page, and when the user browses to the page, the script code embedded inside the Web is executed to achieve the intent of the malicious attacker.1. Reflected XSSA reflection-based XSS attack relies primarily on the site server to return the script, triggering execution on the client side to initiate a web attack.
absrtact: with the rapid development of computer network technology, network security has become more and more people's attention, the form of network attacks are various, many worms, trojan viruses, such as implanted into some Web pages, to network users brought a great security risk. Where XSS cross-site scripting attacks, malicious attackers into the Web page to insert malicious HTML code, when users browse the page, embedded inside the Web HTML code will be executed, so as to achieve the spe
Technical Background
As Web technologies become more and more widely used in our lives, Web application architecture designers and developers have to deal with such a problem, that is, the increasing Web Access volume and load, technologies related to performance improvement have emerged, such as DNS round robin, Server Load balancer, and Cache technologies. If you are interested, you may wish to capture packets for large websites. You can find that many websites use squid reverse proxy to provi

It may be a bit strange to see this question. No one in the cybersecurity circle has defined such a term. At first, I am not sure what kind of term to define, I just defined such a term according to the original term of the attack. If there is a better suggestion to give him a better name, such as "pandatv incense", it is well known.I do not know whether this attack method has been studied. I have never see
