Injecting traffic means inserting forged encrypted messages into the network. It may be done if either the key is known (to generate new messages), or if the key is not known and only an encrypted message and plaintext message is gathered, through comparison of the two. Programs able to do the latter are Aireplay and WepWedgie.
Aircrack-ng is a network software suite consisting of a detector, packet sniffer, WEP and WPA/WPA2-PSK cracker and analysis tool for 802.11 wireless LANs.It works with any wireless network interface controller whose driver supports raw monitoring mode and can sniff 802.11a, 802.11b and 802.11g traffic.
Wireshark is very similar to tcpdump, but has a graphical front-end and integrated sorting and filtering options.. Wireshark lets the user put network interface controllers into promiscuous mode (if supported by the network interface controller), so they can see all the traffic visible on that interface including unicast traffic not sent to that network interface controller's MAC address.
The secure room contained Narus traffic analyzers and logic servers; Narus states that such devices are capable of real-time data collection (recording data for consideration) and capture at 10 gigabits per second. Certain traffic was selected and sent over a dedicated line to a "central location" for analysis.
Kismet has three separate parts. A drone can be used to collect packets, and then pass them on to a server for interpretation. A server can either be used in conjunction with a drone, or on its own, interpreting packet data, and extrapolating wireless information, and organizing it.
The set of algorithms that cipher suites usually contain include: a key exchange algorithm, a bulk encryption algorithm, and a message authentication code (MAC) algorithm. [1] The key exchange algorithm is used to exchange a key between two devices. This key is used to encrypt and decrypt the messages being
The LAN Manager development team had one shared hardware-based analyzer at the time. Netmon was conceived when the hardware analyzer was taken during a test to reproduce a networking bug, and the first Windows prototype was coded over the Christmas holiday. The first 4 bytes of the Netmon capture file format were used to validate the file.
The attacker having physical access to a computer can, for example, install a hardware or a software keylogger, a bus-mastering device capturing memory or install any other malicious hardware or software, allowing the attacker to capture unencrypted data (including encryption keys and passwords) or to decrypt encrypted data using captured ...
