For the past four years, I've been getting unauthenticated spam in the guise of amazon.co.jp (yes I like to look through my spam folder). I get emails daily that always lead to almost legit looking .com's that 302 to 7 character .cn's that then 302 back to google (while setting a PHP session cookie). They all lead to the same IP address that is also SSH accessible.
Taking all of this at face value, what's their game here?
* Collect data on IP addresses as silly as me to click through links?
* Hope someone tries to access their SSH?
* Wait for someone to load an image in their email that has some 0-day?
