Security experts gathered at Caesar's Palace in Las Vegas to attend the annual security conference, Black Hat. Delegates, which include federal agents, corporate security professionals, anti-malware companies and hackers, will hear about new security exploits and undergo training in the latest hacking and malware-authoring techniques.

The edgier Defcon "underground" hacker show also kick offs at the Las Vegas Riviera on Wednesday. The annual gathering, which is marking its 15th year, has less of a business focus and is more popular with enthusiasts.

Two high-profile computer attacks that will influence the topics this year are: the strike on Estonia that crippled the websites of banks, media outlets and government agencies; and a data breach at the parent of TJ Maxx that exposed at least 45 million credit and debit cards to potential fraud.
