Thanks for filling in the blank for me. Couldn't this same concept be used to hack computers as well, though? I was pretty sure that I've heard of such things.
Botnets are primarily used for four different kinds of tasks:
- spam mails
- dDOS Attacks
- proxy services
- distributed hashtable cracking
dDOS and spam are the most prominent uses and the Amazon service was most likely used for simple traffic generation to overload PSN servers.
The latter two are only really used for cracking attempts where a proxy service basically obfuscates your entry path (think, instead of breaking in yourself, you hire someone who hires another one to break in).
Hashtable cracking is used for breaking encrypted passwords. While someone might use them to crack a single password faster, it is usually more commonplace to calculate so-called rainbow tables which are basically a dictionary of hashes and the cleartext name. The tables themselves are then used in a dictionary attack which saves the time of calculating hashes and simply works quicker.
I guess that the attackers used a botnet as a proxy to break in via direct exploits to vulnerable software. The sony statement said that they elevated their priviliges afterwards (you only have the rights of the service you attacked, initially) and worked their way through multiple servers. The statements also notes that admins got curious as multiple machines started rebooting, which can be taken as a sign the exploits did backfire and bring some services down.
They still got through, though, and downloaded the userdata which may or may not be cracked with the method mentioned above.
While some people on the internet seem to know more and say that passwords of users were not encrypted, i don't recall reading that in any official statement and just assume that those were hash'ed at least.
Hope that clarifies things a bit
