The PSN is down, all accounts got dumped by an anonymous hacker and the community is cryin' for answers. 77 million accounts with password and sometimes CC info are worth a lot in several hack chans. This is a very huge case.
Now SONY engaged an external security company to discover the holes in SONY's system and find answers. As I was wondering if there may be some information about the actual case we can find out publically, I researched a bit myself.
One interesting point I found is a not secured access log of a PSN environment.
You will quickly notice the IP 184.108.40.206, which sends requests like a vulnerability scanner.
The IP points to the DoD Network Information Center, based in Ohio USA.
The first log entry of this IP is [03/Mar/2011:07:10:38 -0800]. As the DoD is knows as beeing easy to hack, the anonymous hacker could have used this as proxy.
Maybe SONY might want to take a look at this IP, I hope soon we get some news and details about the case...
