Depending on the web browser one is using the presented warning is slightly different. “Attackers on kat.cr might attempt to trick you into installing programs that harm your browsing experience (for example, by changing your homepage or showing extra ads on sites you visit)”, Chrome warns. The report of unwanted software page from Firefox reads “This web page at kat.cr has been reported to contain unwanted software and has been blocked based on your security preferences”.
In both cases users can get around the warning and visit the site as wanted but statistics show that most users faced with this situation choose not to. A check of the diagnostic report shows that the site was listed as being suspicious as on 104 pages hosted on the domain malware was being downloaded and automatically installed on a visitor’s PC without his/her consent through the use of exploits. This was also later confirmed by the KickAssTorrents team. Their visitors where infected by malware because bad advertisers began serving exploit code instead of ads. Ever since it was detected by KAT the bad advertiser has been removed but Google’s automatic checks will still keep the site flagged for a short while.
