The official page of Kaspersky Anti-virus 6.0 for Windows workstations that shows their anti-hacker settings has been defaced by a hacker who has placed a Nyan Cat animation there instead. However, when you look at the URL you will note that it’s the secure version of the page was defaced and not the standard HTTP (unsecured) version. We came to know about the hack when one of the Anonymous hacker VizFoSho posted the following tweet “#WILD #DEFACE https://support.kaspersky.com/wks6mp3/antihacker … #Kaspersky” Broken CSS is cause of hack. Now page works fine, but the cat is still in HTML source The site was defaced for quite a while until someone at Kaspersky noticed the situation or it was reported to them. The incensed happened on Sunday after noon.
