Russian iTunes users saw a little more (or less) than they expected when a new version of the app displayed pornographic images instead of the films people were trying to watch.
If a movie that a user was trying to download was without an image, it often linked to a xxx.xxx web address, the BBC reported.
The problem arose because, as the Russian iPhones.ru explained: "…the people responsible for iTunes put the 'temporary' link type xx.xx.xx."
And as it happens, "xxx.xxx" is a real porn website.
Of course users took screen shots. You can see them here and here.
However, while customers saw pornographic images, they weren't accidentally subjected to pornographic video, Top F Secure IT researcher Mikko Hypponen told the BBC.
"If someone actually clicks on such a movie and buys it, they won't get a porn movie — they will get what was supposed to be there, a real film, but the image was just wrong," he said.
He added, "It's like when you go to a real-world video rentals store and all the DVDs are there but the covers for some of them are wrong. It's accidental — as I understand the situation, as they were adding content, they were a bit rushed and didn't have images for every single movie cover."
