5 Haktip-19 Beacon Frames and Injection

6 802.11 Beacon Frames and Injection – Notes
Beacon: announces presence wireless device Beacon types Ad-hoc Ssid 32 character identifier Timestamp Capability Channel Data Rate MDK3

7 802.11 Beacon Frames and Injection – Questions
What can MDK3 do: Network probing What is the SSID The 32 character wireless network name What does a Beacon do Announces the presence of a wireless device

8 Haktip-21 Frame Analyzing

9 Frame Analyzing – Notes
ID SSID 32 character text BSSID 6 hex octets Typically the MAC address ESSID All the BSSs in the network Basically the SSID Wireshark Aircrack Airbase-ng MDK3

10 Frame Analyzing – Questions
T/F: the BSSID is always the same as the wireless MAC address F What does the command airbase-ng do: Used with the AT interface to work with the encrypted data. E.g. you can see plaintext before sent and after received
