Pornhub, the popular porn site, has recently closed a hack that has been occurring for over a year, The Guardian reported.

The hack meant that a pop-up would appear on users screens to install an update to their internet browser. Those who agreed to the update experienced the virus infecting their computer. The virus gave control on the user’s computer to whoever created the virus.

The virus then generated fake advertisements that created real profit for other websites, commonly known as “malvertising.” However, this could have just as well have been any other version of virus with much more malicious intent.

The legality of hacking is still in the works. However, two students from North Dakota State, Nicholas Dailey and Matthew Dawson, both students of computer engineering, said that they were not only uncomfortable, but that they believed hacking a computer or the server it’s on is illegal because it’s valued as private property.

According to cgs.ct.gov, the law states that to access a computer or any of its systems without consent is illegal. The website also stated that the penalties range from a class B misdemeanor, meaning six months in prison, or a fine of up to $1,000 or both, to a class B felony, meaning up to 20 years in prison, or a fine of up to $15,000 or both.

The group responsible for the attack was KovCoreG group, according to proofpoint.com. The attack spanned the globe, affecting users in the U.S., Canada, the U.K. and Australia.

Pornhub is one of the top porn sites out there, putting out over 90 billion videos a year, enough for more than 12 videos per person on earth, according to Pornhub’s statistics.

Pornhub’s statistics also revealed that, over their entire network of sites, which includes YouPorn and RedTube, they receive about 115 million daily visits, most of which are made from mobile devices. On average, 74 percent of these visits are made by men, and the average time spent on the porn site is 9 minutes and 36 seconds. That’s a lot of affected computers.
