Know More About Malvertising

Here’s What You Need To Know About Malvertising

Malvertising is a growing global problem that has been affecting individuals and businesses. Before you know how to protect yourself from malvertising, it’s important to understand what exactly “maladvertising” is first!

What is Malvertising?

Malvertising is a harmful practice that spreads malware through different web advertisements. It can be anything from ransomware to adware, and can have a big impact on the security of your devices and/or network.

Judging and putting a specific figure on the scale of malvertising is quite hard as it doesn’t come with red-flags. It is rapid and high-impact, which end up producing detrimental effects on even high-profile websites. A malvertising attack is such a large threat that can work in various methods. However, here are 2 common techniques that affect the websites as well as users.

   ❏ Pre-click: Some malvertising campaigns use a special script or coding that automatically downloaded in the device as the ad loads. This means a user doesn’t have to click anywhere but visiting the page where the ad loads are enough. In this method, an attacker can easily set up a malvertising redirect chain on a landing page that increases the bounce rate of the website.

   ❏ Post Click: As its name sounds, this attack happens when a user clicks on the malicious ad or link. An attacker uses malvertising redirects that make uses moving through several malicious pages. Malvertising through post-clicks can happen through images, links, pages and ads.

How does it work?

Ads are often designed with a call-to-action that encourages viewers to click. Many visitors won’t be able to distinguish between reliable ads and harmful ones, therefore attackers use redirects to send visitors to a malicious webpage. Once on the malicious webpage, a code starts running in the background to download malicious software onto the device. This unintentional download of malicious software or virus is called ‘drive-by download’. Mostly, attackers use this ‘drive-by download’ method to install ransomware and other malware onto targeted computers.

In some more advanced malvertising, attackers install malware directly to the devices from the legitimate site that displays the ad without interacting with the visitors. This can be devastating to a user and even the organization. Most often, companies rely on software and even the third-party vendors for their online ad management that put them into potential risk.

It is not just about clicking malicious ads, malvertising can also be done and harm your device through some sketchier side of the internet. Illegal streaming sites offering flash games, sites offering free cracks/ software/ warez/ keygens, torrent sites, online dating sites, betting sites etc. contain injected malicious ads. These ads affect billions of users and perpetually block access.

Who has been infected in this serious cyber threat?

Anybody can be a victim of malvertising. Attackers target clean and reputed places with a huge number of visitors. Some high-profile companies have been infected previously with malvertising including, Reuters, Huffington Post and The Daily Mail. The sites themselves weren’t infected but the ad providers were blasting malicious ads onto the millions of computers.

What are the measures to avoid malvertising?

Due to the inconspicuous nature, avoiding a cyber threat like malvertising may seem tricky to avoid, but remember these quick tips:

● Reliable Security Solution: A reliable security solution such as antivirus can protect your device from threats you may be unaware of by performing scans on downloads before malicious software is installed onto your device.

● Ensure New Updates: As the tech world is changing regularly, it is also important to update your software, browser and OS with their new versions to battle new threats.

● Avoid Bad Websites: It is one of the most important things you should consider. You should always make sure that the source is legitimate, secure and reputable.

● Use an Adblocker: You can use an ad blocker to avoid any suspicious advertisements display on your website. Also, this will help you avoid clicking on the potentially harmful ads.

● Avoid Clicking On Sketchy Advertisements: Lastly, don’t click on sketchy advertisements. It is recommended that if you see anything enticing in the ad, visit the website from your browser directly and make sure that it is legit.

However, avoiding bad websites and clicking ads won’t always be considered as precautionary measures against cyber threats like malvertising. It is crucial to incorporate reliable security solutions while keeping your computer/software up-to-date with the latest versions.
