I'm assuming the blog the kid used the plugin on had all sorts of info and links to his Twitter account, etc.
They left in his real name in one of the screenshots BTW.
IMO it's quite an entertaining SocEng attack. And he just wanted to get the latest version of a commercial WP plugin! hahaha! I was kind of expecting something more malicious: I thought either the source file he requested contained login credentials or other sensitive info, or he was going to send back a "patched" version with a backdoor in it.
Odd, how he went through all that trouble. Anyone know what the plugin does BTW? I haven't looked, is it that good? :)
