Their ability to monitor, intercept, and decode data as it is in transit makes them useful for:. While wireless packet sniffers are valuable tools for maintaining wireless networks, their capabilities make them popular tools for malicious actors as well. Hackers can use wireless sniffer software to steal data, spy on network activity, and gather information to use in attacking the network.
Logins usernames and passwords are very common targets for attackers using wireless sniffer tools. Wireless network sniffing attacks usually target unsecure networks, such as free WiFi in public places coffee shops, hotels, airports, etc. Spoofing is a type of attack where a malicious party uses information obtained by a wireless sniffer to impersonate another machine on the network. There are two modes of wireless sniffing: monitor mode and promiscuous mode. In monitor mode, a wireless sniffer is able to collect and read incoming data without sending any data of its own. A wireless sniffing attack in monitor mode can be very difficult to detect because of this.
In promiscuous mode, a sniffer is able to read all data flowing into and out of a wireless access point. Since a wireless sniffer in promiscuous mode also sniffs outgoing data, the sniffer itself actually transmits data across the network.

This makes wireless sniffing attacks in promiscuous mode easier to detect. It is more common for attackers to use promiscuous mode in sniffing attacks because promiscuous mode allows attackers to intercept the full range of data flowing through an access point. There are several measures that organizations should take to mitigate wireless packet sniffer attacks.
Monitoring Solutions for Every Need
First off, organizations and individual users should refrain from using insecure protocols. Secure protocols ensure that any information transmitted will automatically be encrypted. If an insecure protocol must be used, organizations themselves need to encrypt any data that will be sent using that protocol. Virtual Private Networks VPNs can be used to encrypt internet traffic and are a popular tool for organizations today. One advantage of reading from a pcap file is that you do not need to be root to execute the script.
Example 1: The -a option will spoof every single DNS request the victim makes and when used in conjuction with -r it will redirect them to -r's argument address.
SpyAgent invisibly records everything users do.
The victim will be redirected to stallman. Example 2: This will spoof the domain eff. When there is no -r argument present with the -a or -dns arguments the script will default to sending the victim to the attacker's IP address. If the victim tries to go to eff. This script uses a python nfqueue-bindings queue wrapped in a Twisted IReadDescriptor to feed packets to callback functions. Python's scapy library does the work to parse and inject packets.
Injecting code undetected is a dicey game, if a minor thing goes wrong or the server the victim is requesting data from performs things in unique or rare way then the user won't be able to open the page they're trying to view and they'll know something's up. This script is designed to forward packets if anything fails so during usage you may see lots of "[!
This is OK. If they don't get hooked on the first page just wait for them to browse a few other pages. The goal is to be unnoticeable. Do things like create an official looking Facebook pop up saying the user's authentication expired and to re-enter their credentials. Skip to content.
