Subscribers of one of YouTube's most popular channels, WatchMojo, were greeted with an unusual surprise on Wednesday evening, as a couple of hackers, known only as Obnoxious and Pein, hacked the lineup of the channel's videos.

The two hackers then proceeded to rename almost all of WatchMojo's videos with the title "HACKED BY OBNOXIOUS AND PEIN twitter.com/poodlecorp." Since the channel was compromised, the hackers have uploaded two new videos, Top 5 Facts About the Yakuza and a video about Neanderthal myths. Apart from these, however, the hackers have not touched anything else on the channel.

Though most of WatchMojo's videos still remain hacked as of writing, the popular channel announced that it is fully aware of the hack. WatchMojo further stated that it has already contacted YouTube about the incident and that it is already starting to fix the changes to its videos.

The identity of the two hackers has not been determined so far, though the cyber attackers have been quite tame with regards to the changes they initiated to the hacked channel. Notably, when the hack went public, some internet trolls have even encouraged the hackers to delete the channel and all its videos. Thankfully, the hackers seemed to have opted for a rather harmless hack instead.

Nevertheless, the massive security breach on the popular channel has turned heads in the computer security world. After all, the hack could have easily compromised the channel's 12 million subscribers, who could have been redirected by the hackers to websites that deliver Ransomware.

WatchMojo boasts more than 12 million subscribers on YouTube, with the channel becoming very popular due to its daily Top 10 uploads. Its signature lists tackle almost everything under and beyond the Sun, from facts about pop culture, mythology and even space.

Since its acknowledgment of the hack, WatchMojo has been pretty silent. Its videos, however, have started reverting back to their old titles. With the channel's penchant for making Top 10 lists, however, it would not be surprising at all if this very hack makes it to a list pretty soon.
