Forbes Article Reformed Hacker Looks Back, brings to light just how vulnerable Web2.0 technology is to hackers like hacker legend Kevin Mitnick.

Kevin David Mitnick is a computer security consultant who was a controversial computer hacker in the late 20th century. In 1999, Mitnick admitted to the authorities [...]. Mitnick served five years in prison, of which four and a half years were pre-trial, and eight months were in solitary confinement. He was released on January 21, 2000. During his supervised release, which ended on January 21, 2003, he was initially restricted from using any communications technology other than a landline telephone. Mitnick fought this decision in court, and the judge ruled in his favor, allowing him to access the Internet. (Wikipedia)

Where's Kevin Now? Mitnick now runs Mitnick Security Consulting, a computer security consultancy (Wikipedia).

As for the weaknesses in Web2.0, quoted from Forbes:

What do you see as the biggest threats to cybersecurity today?

Cybersecurity used to be about the network or operating system. Now it's more at the application layer. Companies and their contractors build their own applications hosted on a public Web site, and the people who write them aren't trained in secure coding. The mistakes they make can be leveraged to break the system.

...and he's right. People are pumping out web-based applications all the time and I imagine the only protection they have remain vulnerable hackers like Kevin. I imagine this will become a bigger issue as software becomes a thing of the past and everything is web-based.
