What is malvertising or malicious advertising? How is it different from online advertising?
In today´s post we will briefly explain the differences between these two concepts: adware and malvertising.
What is Adware?
Adware is the program that fills our browser with toolbars and unwanted advertising. Most of the time it is downloaded without our knowledge. During the process of downloading and installing a specific program, many message boxes ask us if we want to install the adware program. The problem is that, in the rush to have the program running as soon as possible, we tend to click on “next” button without even reading these messages.
And…What is Malvertising?
Malvertising (aka malicious advertising) is a practice that involves malicious activity. In this type of attack, victims can be deceived for weeks and even up to months. These attacks can be delivered through different vias:
- One option is for hackers to use online ads to hide pieces of malware in them, and thus exploit vulnerabilities in browser plugins or outdated software. The whole process is carried out without users´ knowledge. As soon as users access a website, the exploit begins to look for vulnerabilities. When it finds one, it exploits it.
- Another option is to use legitimate banners or online ads. That way, when users click on a link on them, they are either redirected to a malicious site or a malicious download is initiated.
The continuing rise of malvertising is translating into an increase in the use of tools to block online ads. This trend represents a huge threat to online advertising companies.
How can we protect ourselves against malvertising?
With RITech, organizations can choose between blocking unwanted online ads or allow their employees to see and interact with them, but always in an isolated mode, so that no malware can ever infect their endpoint devices.
