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

I have understood this attack for a long time and do not understand what it means to "rebind. After A little understanding, I found that the attack principle is literal. Refresh the DNS A record and bind it to another address. In the following section, I reference the note of a fairy "To mount a DNS rebinding

are originally planning to access a website are taken to other websites that hackers point to without knowing it. There are multiple implementation methods. For example, attackers can exploit the DNS Cache Server vulnerability on the internet ISP side to attack or control the attack, so as to change the response results of the user's access to the domain name in

server. Another clever approach is to use DNS. There are many network vendors that have their own DNS servers, and allow anyone to query, and even some are not their customers. and general DNS uses UDP,UDP is a connectionless transport layer protocol. With the above two conditions as the basis, it is very easy for those attackers to launch a denial-of-service

Event Causes and analysis This incident is a linkage event, mainly divided into two parts: 1, the Dnspod site's DNS server by more than 10Gbps traffic DDoS attack the suspect because it is the competition between the network game between the business, causing a server operators launched thousands of zombie hosts to Dnspod launched a DDoS flood attack, Causes the

Name Service provider 114DNS found a "monitoring data anomaly." Then, the security team successfully traced to launch this DNS hijacking attack "culprit", and the first time the attack to the Tp-link and other domestic mainstream router manufacturers. 114DNS and Tencent computer stewards say a new round of DNS phishi

In the previous article (man-in-the-middle attack ARP poisoning), we discussed dangerous hacker attacks and practical ARP poisoning principles. In this article, I will first discuss how to detect and prevent ARP poisoning (or ARP spoofing) attacks, and then I will review other man-in-the-middle attacks-DNS spoofing.ARP cache attacks are very dangerous. It is important to create security awareness and analyz

Domain Name Server authorized by baidu.com to the local DNS server. The local DNS server continues to initiate a query to baidu.com to obtain the IP address of www.baidu.com. After obtaining the IP address corresponding to www.baidu.com, the local DNS server transmits the IP address to the user in the form of a dns re

Recently in doing OpenWrt platform, DNS use is DNSMASQ, but through the board to the Internet, the PC's DNS is set to board the time, found that Baidu, etc., but the company mailbox can not open. The domain name of the company mailboxxx-xx-notes.xxx.com.cn form, so the DNSMASQ log opened to see the next. Finally found the problem.How to open DNSMASQ log1. Find/etc/dnsmasq.confIn the OpenWrt system, dnsmasq.

This article will introduce several main DNS attack methods. I hope this technology will help you. Use DNS servers for DDOS attacks The normal recursive query process on the DNS server may be exploited as a DDOS attack. Assume that the attacker knows the IP address of the at

Like smurf Currently, many DNS servers support EDNS. EDNS is an extended DNS mechanism, which is introduced in RFC 2671. Some options allow the DNS to reply to more than 512 bytes and still use UDP, if the requestor points that it can handle such a large DNS query. Attackers have used this method to produce a large am

hundreds of thousands of users are redirected to a trap site set up by hackers by embedding a server with a cache poisoning attack. The severity of this issue is related to the number of users who use domain name requests. In this case, hackers who do not have a variety of technologies can cause a lot of trouble, so that users can tell others their online banking account passwords and online game account passwords in a confused manner. In this way, t

After a series of recent retaliatory attacks caused by the closure of the file sharing website Megaupload, Anonymous's Denial-of-Service "Cannon" has greatly reduced the number of shells fired later. Although Anonymous members intend to break the INTERPOL website in February 28 (mainly through the online version of the "low-track Ionic Gun" Denial-of-Service tool ), moreover, some vulnerable websites (including most recently websites affiliated with Panda Security) have been destroyed, and the
