To say there are a lot of ads on the internet would be an understatement. Research shows that the average American is exposed to over 10,000 ads per day, most of which appear on the internet. You can’t always trust ads on the internet, however. Some of them are designed specifically to spread malware. A cyber threat known as malvertising, it includes the following types.

#1) Hidden Inline Frames

Hidden inline frames is a common type of malvertising. Inline frames are embedded Hypertext Markup Language (HTML) documents, such as web pages. Websites may feature inline frames that contain the content of other web pages. Hackers may use hidden inline frames to trick users into downloading malware from these other web pages. The inline frames may look like native ads, but they are actually embedded web pages that contain malware.

#2) Drive-By Downloads

Drive-by downloads are often used for malvertising purposes. Drive-by downloads involve a user unknowingly downloading malware or malicious code. Normally, users must manually download software from websites. Drive-by downloads are automatic and occur without any action taken by the user. Users may load a web page with a malicious ad, which will then infect their computer with the malware or malicious code.

#3) Fake ‘Close’ Buttons

Some malicious ads trick users into downloading malware by leveraging a fake “close” buttons. Most ads feature a “close” button. It typically consists of an X in the corner of the ad. Malicious ads, though, may use a fake “close” button. They still feature an X in the corner, but clicking this X won’t close them. Instead, it will deploy malware onto the user’s device.

#4) Sneaky Redirects

Another common type of malvertising is sneaky redirects. Nearly all ads on the internet point to another web page. Sneaky redirects involve tricking users into clicking an ad by sending them to a different web page other than what they expected. Users may assume that an ad points to a legitimate business web page. Clicking the ad, though, may redirect them to a different web page, such as a malicious web page that infects their device.

#5) Rogue Security Software

You’ve probably encountered ads for rogue security software before. They typically promote anti-virus software or services. But rogue security software is a type of malvertising, and it may be used to infect your device with malware. The rogue security software ads may ask you to perform a system scan, for instance. Upon initiating the fake system scam, your device will become infected with malware.
