London Firms Risk Drive-by Hacks
Source: AnywhereYouGo
City [of London] and financial institutions are at risk from 'drive-by' hackers because they have not secured their wireless networks.
A group of security experts have revealed how easy it is to access data from outside a company building. Consultants from Orthus picked up signals from 124 company wireless local area networks (Lans) in and around the City.
The signals from wireless Lans in an office have a range up to 200 meters, but Orthus found two-thirds were unencrypted and easily accessible by anyone with inexpensive equipment.
The consultants needed only a laptop, a wireless network card and free software downloaded from the net.
Eight areas of the capital, including the City, home to the UK's largest financial institutions, were tested in the study, sponsored by security specialist RSA.
Although security was tighter in the City, some 48 companies out of the 124, including some well-known institutions, were still exposed, with more than half using unencrypted signals.
Anyone with malicious intent could have grabbed user IDs, passwords, and even wire fund transfers, said Richard Hollis, managing director at Orthus.
