UPDATE @ 13:16 – It appears a sister site hackaserver.com was also compromised (through analysis of email headers). The site also appears defaced like CTF365.com below.
It appears that the well funded and connected online pentesting lab, CTF365.com was compromised within (at least) the last few minutes. At this point it is unsure to what degree the site/infrastructure has been compromised, but it is safe to say that a number of user accounts of the pastebin document have been verified. Currently the site shows a simple ASCII art front page claiming the hack was completed by CyberSelfie.

Time to get some unique, per site, email addresses everybody!
