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.

Security best practices for Enterprises

We have seen a ton of attacks against WPA/WPA2, both Personal and Enterprise. Based on our experience, we would recommend the following:

  1. For SOHOs and medium-sized businesses, use WPA2-PSK with a strong passphrase. You have up to 63 characters at your disposal. Make use of it.

  2. For large enterprises, use WPA2-Enterprise with EAP-TLS. This uses both client and server-side certificates for authentication, and currently is unbreakable.

  3. If you have to use PEAP or EAP-TTLS with WPA2-Enterprise, then ensure that certificate validation is turned on, the right certifying authorities are chosen, the Radius servers that are authorized are used and finally any setting that allows users to accept new Radius servers, certificates, or certifying authorities is turned off.

Pop quiz – attacking WPA-Enterprise and RADIUS

  1. FreeRadius-WPE is a:

    1. Radius server written from scratch

    2. Patch to the FreeRadius server

    3. Ships by default on all Linuxes

  2. PEAP can be attacked...
