Computer giant Microsoft's official YouTube channel appears to have been hacked Sunday morning. All of the official videos, including recent ad campaigns, have been removed from the account. In their place are short clips soliciting advertisers, not surprisingly, as the channel has some 24,000+ subscribers.

As of 1:30 p.m. ET, four videos have been uploaded to the account, all time-stamped within the past two hours. A fifth video, most recently uploaded, seems to have been removed. The video, "Garry's Mod - Escape the Box," featured what appeared to be an animated gunman shooting at the inside of a construction box.

The channel's description reads, "I DID NOTHING WRONG I SIMPLY SIGNED INTO MY ACCOUNT THAT I MADE IN 2006 :/."
