Are you referring to lulzsec? There attacks have mostly used SQL injections. And yes most big company websites are not much more secure than anything else.
Nope. Upon further research apparently the webmasters were really THAT incompetent. SQL injections and simple bruteforcing don't count as technical genius.

A hacked site can only be the result of incompetence or negligence. When you handle your data correctly, there is no amount of genous that can magically alter the laws of computation to make it break open.
I have a related question. I'm an inexperienced desktop application developer who is try to transition to web development. I'm getting myself acquainted with LAMP (Perl) and the necessarily markup (HTML/CSS) and a bit of JS.
I just realized that I'm very ignorant regarding security measures. Is there some uptodate web archive out there that I can trust to inform me of the latest security holes (server/client side of any type) and how to combat them?

No there are just generic vulnerabilities you need to know about and learn while developing your web applications e.g. SQL injection, file inclusion, Cross site request forgery. There are good books on this subject, just Google it.
