Protect Yourself Against Malvertising
We all know spam emails. Those annoying emails that flood our inboxes and build up to the point of absurdity. Since we’ve all heard the warnings about opening suspicious emails or clicking on links inside spam emails, we ignore the urgent subject lines and delete our chances of inheriting millions of dollars from an African prince who was kind enough to leave all his riches to us. But did you know, that there is a new form of spam? Malvertising.
What is malvertising?
Malvertising is spam in the form of internet ads. Cybercriminals use internet ads, even on trusted websites, as a vehicle for viruses. How malvertising differs from traditional spam emails is that you don’t have to click on the ad for your computer to become infected! And once the virus is installed onto your computer it can wreak havoc! Malware can delete and modify files, allow hackers to gather information about you or steal your personal information, or seriously affect the performance of your device.
Wondering how a virus from an ad can be downloaded without clicking on the ad? Security flaws in ad programming, most notably Adobe Flash. Just by visiting a website that has infected ads you become vulnerable to cybercriminals. They use ad networks to place the virus infected ads onto a publisher’s website which can then be automatically downloaded onto a victim’s device.
So how can you protect yourself?
- Use an ad-blocking browser plugin. This is the most effective way of making sure malvertising ads don’t get the chance to download viruses onto your device. However, using an adblocker will also block legitimate ads of the websites you visit.
- Make sure your plugins and web browser are up to date and routinely check for upgrades. As cybercriminals develop new threats, companies develop software and program upgrades to keep you safe.
- Have your browser flag malicious content. Under your browser’s “Settings” there will be a “Security” or “Privacy” section where you will find an option to turn on/off “Safe Browsing.” Turn on “Safe Browsing” and your browser will warn you if your visiting a malicious or questionable site.
There is no sure-fire-way to protect your device completely. Cybercriminals are always creating new ways to infect your device and sabotage your files and steal your information. However, there are proactive steps that you can take to protect your device, information and identity.
