A new study has again warned that porn site users are opening themselves up to attacks from cyber criminals.

Porn sites users are at risk because the sites they frequent not only often harbour malware, but also entrap users in various schemes and shady deals.

The report, which highlights the dangers that porn site users face, was prepared by the International Secure System Lab.

Dr Gilbert Wondracek, who led the study, said that the intense competition amongst the online porn industry made matters far worse: ”They have almost inadvertently created a whole ecosystem that’s easy to abuse for cyber crime on a large scale. There are studies looking at the profitability and economics of the industry but we are the first to come at it from a security and more technical point of view.”

The techs at the International Secure System Lab built their own porn sites and quickly discovered that many porn site users are very vulnerable to computer viruses and loopholes.

Dr Gilbert pointed out that the study had been basically carried out to test the commonly held assertion that porn site users are at risk. He added: “There are studies looking at the profitability and economics of the industry but we are the first to come at it from a security and more technical point of view.”

Dr Gilbert stressed that it was often hard for the average user to tell a porn site which is honest, compared to one that might be hiding malware threats.

Of the 35,000 porn site domains studied in the report, it was discovered that 90% were ‘free’ sites and that these acted as ‘funnels’ for sites that require payment to view their content.

The 35,000 domains published some 269,000 individual websites. The study looked at all these sites and discovered that a touch over 3% were booby-trapped with malware, including viruses, spyware and adware. What’s more, many other sites used tools such as JavaScript catchers which make it hard for porn site users to actually leave the site.

Other sites immediately transferred those people hoping to view a video, to say a number of affiliate sites, which creates a circle of click trading. Dr Gilbert said: “Visitors are being abused as click bots. It’s cut-throat competition. Everybody tries to get as much traffic as possible.”

Porn site users are being told to be aware of “safe browsing modes” when visiting such websites and to keep their anti-virus software up-to-date.
