Late Wednesday evening, hackers operating under the name Poodle Corp. compromised the WatchMojo.com YouTube channel and started tagging dozens of videos.
The account hijacking was quickly detected, and the company turned to YouTube for assistance.
WatchMojo is known for their Top 10 videos on a number of topics. In 2013, the brand was listed as the 50th largest channel on YouTube. On Twitter, the company said they're aware "of the hack on our YouTube channel and we're working with YouTube to fix the changes."
