Advertising builds trust in a brand, and that trust makes us feel secure enough to click on a banner ad of a brand we know while browsing the Internet. However, danger could lurk here in the form of “malvertising”.

This insidious hacking technique actually has malicious advertising banners masquerade as legitimate ones by mimicking colors, fonts and layouts. When you click on the banner, instead of heading to your intended site, you are actually redirected you to a third party site. Often, this site promptly informs you that you have a virus. Now here is the especially clever part: you are offered a solution to this problem, but the malware is actually contained in the “fix” you download to get rid of the “virus” you were allegedly infected with.

By using social engineering and our own browsing habits against us, malvertising attacks can thus penetrate networks and wreak havoc with our confidential data.

There are ways to prevent this and we go into more detail in our brief video on this topic. Stay informed about this hard-to-detect and difficult-to-prevent form of attack. Also, don’t forget to leave a comment if you have had any experiences from “malvertising” attacks to help out your fellow network administrators.
