Four Methods for hackers to intrude into wireless networks

The following are four main methods for hackers to attack:

Some foreign professional media wrote that wireless broadband Internet access is becoming more and more popular in the United States and Europe. not only many offices, airports, coffee shops, restaurants, and so on have begun to provide wireless Internet access services, even many home users have wireless broadband Internet access. However, some foreign experts recently pointed out that many wireless networks have not taken security protection measures, which is not only vulnerable to hacker intrusion, but even difficult to trace the culprit afterwards.

Experts warned that hackers often use the following four methods to intrude into wireless networks:

Method 1: ready-made open network

Process: hackers scan all open wireless Access points (Access Points). Some of the networks are for public use, but most of them are because users are not properly configured.

Attempt: free Internet access, attack a third party through your network, and explore other people's networks.

Method 2: detects intrusion into wireless access devices

Process: A hacker first sets up a disguised wireless access device on an attempted network or in a public location, so that the victim may mistakenly think that there is a wireless network available. If the hacker's camouflage device signal exceeds the real wireless access device signal, the victim's computer will choose a camouflage device with a strong signal to connect to the network. At this point, hackers can wait to receive the password entered by the victim, or enter the virus code into the victim's computer.

Attempt: attackers can detect intrusions, steal passwords or identities, and gain network permissions.

Method 3: WEP encryption attack

Process: hackers detect WEP Security protocol vulnerabilities and crack communications between wireless access devices and customers. It may take several days for a hacker to crack a passive attack using the monitoring method, but some active attacks can be cracked in just a few hours.

Attempt: illegal intrusion detection, password theft or identity theft, and obtaining network permissions.

Method 4: day-to-day attack

Process: similar to the second method, a hacker sets up a disguised wireless access device and a virtual private network (VPN) server (such as SSH) that is the same as the attempted network ). If the victim wants to connect to the server, the fake server sends a Response Message to connect the victim to the fake server.

Attempt: illegal intrusion detection, password theft or identity theft, and obtaining network permissions.

The four methods of hacker intrusion have been introduced to you, and we hope you can master them as soon as possible.
