Internet advertisement networks provide attackers with an effective venue for targeting numerous computers though malicious banner ads. Such fake ads may take the form of Flash programs that look like regular ads, but contain code that attack’s the visitor’s system directly or redirects the browser to a malicious website.
The popularity of social media platforms such as Facebook has also led to a number of scams that spread virally across the social network, tricking users into taking surveys and earning the scammers money. Make sure as a user that you stay informed about the latest scams spreading fast across Facebook and other internet attacks.
Who is responsible?
It should be everyone. The host of the website should be actively involved in making sure that the content is malware free, the ad producers should also be active in preventing their ads from being hacked and the users should be alert as well.
