First, several basic concepts Cookie spoofing means that, in a system that only performs cookies verification on users, the cookies can be used by modifying the content of cookies. User permission to log on. (Well, I have my own definition. Don't laugh) So what is cookies? Here I will give you a professional explanation. Cookies are a file stored in the browser directory. This file records the information you visit a specific site, and can only be rea

In the previous article, we have discussed four forms of man-in-the-middle attacks: ARP cache poisoning, DNS spoofing, and session hijacking. In this article, we will study SSL spoofing, which is also the most powerful form of man-in-the-middle attack, because SSL spoofing can launch attacks by using services trusted by people. First, we will discuss the theory o

Cross-network segment ARP spoofing attacks Cross-network ARP spoofing is much more complex than ARP spoofing of the same network segment. It must combine ARP Spoofing with ICMP redirection attacks. Assume that A and B are in the same network segment, and C is in another network segment. For details, see table 2. Table

We have learned from the article ARP working principles that the host will save and update the local ARP cache table in two cases,1. When receiving the "ARP broadcast-request" Packet2. When an "ARP non-broadcast-reply" packet is received We can see that the ARP Protocol has no authentication mechanism, and any host in the LAN can forge ARP packets at will. The ARP protocol design is inherently flawed. Assume that there are three hosts (GW refers to the gateway) in the LAN. The host name, IP

in the trusted lan. It is efficient but insecure. It is a stateless protocol and does not check whether a request packet has been sent or not.) Is it a legal response, all received ARP reply packets or ARP broadcast packets, including ARP request and ARP reply, are accepted and cached. This provides the possibility of ARP spoofing. malicious nodes can publish fake ARP packets to affect the communication between nodes in the network, or even act as a

Many Computers in the organization suddenly cannot access the Internet. This situation occurs on multiple computers, and many computers are XP SP2 system, and the firewall is enabled. But after careful observation, we found that most computers have enabled the file and printer sharing service, because the ports 137, 138, 139, and 445 opened by this service are exactly It is recommended that you do not open the port frequently used by viruses, or disable the port of the service on the firewall se

Article Title: arp spoofing and sniffing in linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. It is a record process. After playing cain for a long time in windows, I found that he occupies a high cpu. The key is that there is no command line. Today, I also met a linux user who directly obtained the root passw

Linux ARP spoofing sniffing internal penetration testI have already told the related personnel that the smtp and pop protocols for mailbox authentication should be encrypted. Otherwise, it is too easy for someone to sniffer the plaintext password in the company's intranet. In addition, the mailbox password is shared with bbs, bbs also uses the http protocol and does not use https, which is a problem. Although the network we control has been processed,

This is a DNS spoofing experiment that uses Kali's ettercap. There are three machines, the victim, the attacker (virtual machine), and the Web server.The victim's 124.16.70.105.The virtual machine is 124.16.71.48The Web server is 124.16.70.235 and is 80 portsSubnet mask is 255255.254.0Little White has deceived success, the target domain of deception is hao123. But his experiment found that using the victim ping hao123 when the DNS

The route that is said here, is thousand yuan above the route, 1000 blocks below does not discuss. Now a lot of enterprise routing, all say that there is such a function,But such a function is to have the premise that the computer must be directly routed, if separated from the switch, these functions for the computer, the shape of a fake. and LAN inside the broadcast storm, ARP spoofing these problems are very common problems, the problem is not big,

MAC Address Spoofing on LinuxGuideThe NIC manufacturer marks a 48-bit GUID on each NIC (NIC) when it leaves the factory. This GUID is the MAC address of the NIC, used to determine the identity of a network card. The 24-bit high MAC address is called OUI, which is the identifier of the Organization that sets the MAC address for the NIC. As a result, the MAC addresses set for different organizations will not conflict. Although the MAC address is specifi

URL Structure Let's take a closer look at URLs and its related security meanings. A "funny" method of URL exploitation has been discovered by spam advertisers for a long time, but now the "kb" (Knowledge Base) Spoofing and the article published in crypto-gram in February, this allows the URL to do more. Although most Internet users associate WWW addresses or FTP with URLs, the use of uniform resource locators (URL, unified Resource Locator) is more co
