Please take a look to this link. The info from pastebin lead us to the dump of WHMCS db, root files, cpanel, and customer info (CC, license, etc). WTF !!!. And WHMCS twitter also got hacked. Hahaha. https://twitter.com/whmcs.
Discussion in WHT :
If you want to get the mirror link for WHMCS db, please contact me. :D
Happy Hacking :D
