Malvertising

Malvertising

Malvertising is a type of cyber attack that unfortunately happens often these days, but is seldom discussed. The definition of a malvertising attack is one where a hacker or cyber criminal infiltrates an advertisement on a website with malware and viruses, unbeknownst to the website owner, that ultimately infect the computers of anyone who views the website or clicks on the ad. The result is that the malvertising architect, the cyber criminal, now has access to millions of consumer’s websites simply because they visited a website they may frequent on a daily basis.

Sometimes malvertisements are placed on the website by the website owners, who communicate directly with what ends up being a cyber criminal, and sometimes these hackers get their ads included in an online advertising network’s portfolio, which is placed on their client’s websites.

Unfortunately, these infected malvertising ads go undetected by the website owns or their online ad networks for weeks or months, meantime infected millions of computers around the world. The reason the malware laden ads go undetected for so long is because they have no affect on the actual website so there are no alerts or red flags that signal to the website owner that something is wrong.

Additionally, if a consumer visits 100 different websites in a day and then realizes the next day that they have malware installed on their computer but they know that they did not actually click on any ads while perusing the Internet the day before, they would have no way of knowing where the infection came from. This is one of the most unfortunate parts of malvertisements – it does not require the consumer to actual click on an ad in order to get the malware.

There are a couple things that a consumer can do to prevent infection by a malvertisement.

  • 1First, a consumer can set up their website browser or use a website browser that will detect malware ads on websites. Google Chrome is a great example of a website browser that has the detection abilities to prevent a user from engaging with an infected website.
  • 2Second, you should always install antivirus software to protect your computer.
  • 3Third, these cyber criminals often use Adobe Flash products to install their malware, so it's important to keep this program updated.
  • 4Finally, installing an ad blocking software that will remove ads from websites is another great way to prevent malvertisements.

Take a look at the articles below for more information on how you can protect yourself against an infection by a malvertisement.
