I think if I were inclined to break into computer networks and systems I'd want to draw as little attention to myself as possible. No Twitter, no website, no blogs, nothing. All of that leaves a trace, in one way or another. I'd be the ghost in the machine. Seems like they've all gone the wrong way about it.
Exactly what I was trying to say earlier. But, these particular hackers must simply want attention so much that it counter acts their ability to lay low.
However, I'm confused what they want really. If it's all about "gov and corporations, bad", then how is exposing innocent bystanders personal info or directly attacking the gov and FBI to reach whatever goal they might have. It's just going to make the internet even less anonymous, more controlled by gov and we'll maybe even lose net neutrality for all.
There are some fundamental design "flaws" in the current internet architecture that could be exploited by someone with dubious motives. However, maybe some additional security measures are already coming with the transition to IPv6/IPSec, but the transition to IPv6 is going to take many many years. There's still the engineer that configures something wrong...
