Apparently Sony doesn't really rate-limit logins (say, per IP), leaving their customers open to password bruteforce attempts I'd love to know from someone in the business whether bruteforce attempts like this typically come from a single IP, multiple IPs or a unique IP per account break-in attempt. If it's anything but the latter, one would really hope a company as high-profile and as targeted as Sony would be checking more thoroughly for this kind of stuff.
