[Nefarious]

This is amateur shit, you can jack any skype you want, granted you are

A. Good at SE (requires less info)
OR
B. SE w/all required info

req info to jack a skype:

month and year skype acc was made in
email it was made with
first name (can usually bs this)
state/country it was made in

boom, done, jacked

premium skype accnts usually needs paypal email address, home address, sometimes name on pp acc or card

Godaddy domains, dox em, SE, done

For skype, alternatively you can try to get your hands on the REAL leaked skype 0day, not the one that doesn't do anything : P, this will let you do remote code exec on your victim, fun stuff.

Since you are so 1337, jack my skype.
