Thankfully Centcom does not keep classified information on its twitter account but that doesn't make the hack any less embarrassing.
For example they seemingly published the home addresses of military Generals
After a half hour of being attacked, the Centcom Twitter page was taken down.
As of 1:20 PM the Centcom YouTube account is sill displaying an ISIS masthead and ISIS videos
.@CENTCOM response: We can confirm that our twitter account was "compromised. CENTCOM is taking appropriate measures to address the matter."
