WiFi vulnerabilities: Advances and incidents in 2010

By Ajay Kumar Gupta, Network World |  Security, security, wi-fi

The 802.11n standard was ratified in 2009 and WiFi really took off in 2010, with support showing up in an array of consumer electronic devices. Unfortunately security related issues escalated right along with growing acceptance.  Here's a look back at the WiFi security issues that emerged this year.

Virtual WiFi leads to rogue access points: The Windows 7 virtual WiFi capability, or soft AP, became popular in the early part of 2010, with users downloading millions of copies of free programs such as Connectify to exploit feature.  But it didn't take long for security experts to see the danger and warn organizations about the possibility of employees creating possible rogue access points using virtual WiFi. These rogue APs can create a hole in your network security and allow an unauthorized user to "ghost ride" into the corporate network.  This type of access can be difficult to notice using traditional wire-side techniques, so experts advocated watching carefully for the appearance of rogue APs while upgrading machines to Windows 7.

MiFi gains popularity:  Steve Jobs experienced a WiFi malfunction during the iPhone 4 launch in June 2010. An examination after the fact revealed that around 500 mobile hotspot networks were in use, supporting some 1,000 WiFi devices. This incident brought to light the security issues that can crop up from use of MiFi, and experts suggest using dedicated monitoring solutions capable of detecting these unauthorized devices on a 24x7 basis.

Google's WiFi snooping controversy: In the middle of 2010 Google admitted that their cars used to collect Street View information also mistakenly collected payload data from unsecured WiFi networks. Many viewed the act as a privacy breach because the data collected included personal information such as email, passwords, fragments of files, browsed Internet data, pictures, video clips, etc. The controversy was a major black eye for Google but served as a big wake up call for all those WiFi users who still haven't secured their WiFi networks.  

Russian spies and peer-to-peer WiFi links: The use of private, adhoc WiFi networks for secret communication came to light when the FBI arrested a group of Russian spies who were using the tools to privately transfer data. Such adhoc WiFi networks set up links between WiFi users without using a centralized WiFi router. Corporations are advised to deploy monitoring tools that can snoop out such connections.
