Vivek Ramachandran

Vivek Ramachandran has been working on Wi-Fi security since 2003. He discovered the Caffe Latte attack and also broke WEP Cloaking, a WEP protection schema, publicly in 2007 at DEF CON. In 2011, he was the first to demonstrate how malware could use Wi-Fi to create backdoors, worms, and even botnets. Earlier, Vivek was one of the programmers of the 802.1x protocol and Port Security in Cisco's 6500 Catalyst series of switches, and he was also one of the winners of the Microsoft Security Shootout contest held in India among a reported 65,000 participants. He is best known in the hacker community as the founder of SecurityTube.net, where he routinely posts videos on Wi-Fi security, assembly language, exploitation techniques, and so on. SecurityTube.net receives over 100,000 unique visitors a month. Vivek's work on wireless security has been quoted in BBC Online, InfoWorld, MacWorld, The Register, IT World Canada, and so on. This year, he will speak or train at a number of security conferences, including Blackhat, DEF CON, Hacktivity, 44con, HITB-ML, BruCON Derbycon, Hashdays, SecurityZone, and SecurityByte.

Time for action – sniffing data packets for our network

In this exercise, we will learn how to sniff Data packets for a given wireless network. For the sake of simplicity, we will look at packets without any encryption.

Follow these instructions to get started:

  1. Switch on the access point we had named Wireless Lab. Let it remain configured to use no encryption.

  2. We will first need to find the channel on which the Wireless Lab access point is running on. To do this, open a terminal and run airodump-ng --bssid 00:21:91:D2:8E:25 mon0 where 00:21:91:D2:8E:25 is the MAC address of our access point. Let the program run, and shortly you should see your access point shown on the screen along with the channel it is running on:

  3. We can see from the preceding screenshot that our access point Wireless Lab is running on Channel 11. Note that this may be different for your access point.

  4. In order to sniff data packets going to and fro from this access point, we need to lock our wireless card on the same channel...
