Sunday night, 10pm. Your standard in-bed Facebook browse turns to something more X-rated in one of the darker crevasses of the internet. Goodnight, indeed. Just know that watching porn on your phone poses more risks than just a dodgy internet history.

According to tech firm Wandera, smartphone smut is much easier for hackers and cyber criminals to expose and exploit. Operating systems – Android in particular – are much less secure than desktop equivalents, meaning that hackers can tap into your porn tastes with malware: software designed to deliberately disrupt, damage or gain unauthorised access to your data.

A study by the firm found that more than two-thirds of men who watch porn do so on their mobiles. Aside from viruses and data theft, the risk is that hackers attempt to blackmail users by threatening to reveal your viewing habits to your family, or even your employer. Wandera also found that a small number of idiots even watch porn on their work phones – fetish for a disciplinary on all fronts.

“Adult, extreme and illegal content categories are far more likely to leak data, employ unencrypted technologies and otherwise expose organisations to risk,” said a spokesperson for the company. Which is basically techspeak for “don’t do it”. Watch on a desktop instead and make sure your antivirus is up to date.
