Many people use adblock (Including me) and I noticed that a lot of businesses are stating that adblockers are bad and people should not use them.
Don’t listen to it. Adblockers provide an important role in security for blocking compromised adverts, malvertising, clickjacking and malicious web resources, which will infect users with all sorts of malware. Anything from Ransomware to spyware can infect the user.
What is malvertising?
Malvertising is the use of 3rd party advertisements to infect users with malware. Often these malicious adverts contain scripts that redirect the user through a series of exploits that infect the user with malware. The most common type of malware used as a payload of exploits is ransomware.
What is clickjacking?
Clickjacking is the use of adverts to hide a malicious webpage on top of something that the user can interact with on the parent page. For example, websites offering downloads sometimes have ads which cover the download button, so the user clicks on the malicious webpage, however they actually meant to click on the real download button. As a result of the clickjacking attack, the user is now infected with malware.
I understand that you need income
Of course, everyone needs some sort of income to stay alive and keep doing what they do, but companies and businesses should not blame people that use adblock for their loss of income. Instead, they should blame the people that host malicious advertisements, as research has shown that malicious adverts are on the rise, meaning that the rise in adblock could actually be caused by the rise in malvertising.
What kind of exploits are being used?
Malwarebytes has discovered the use of both the Neutrino exploit kit and the RIG exploit kit in malicious adverts. These exploits were infecting the user with CryptoWall ransomware. You can learn about a recent example of malvertising and the exploit kits named above here.
Just to be clear. I am not against the use of adverts to gain income. I am against the use of malicious advertisements. (In other words I just don’t want to be infected with malware)
I would recommend Malwarebytes Anti-Exploit to protect against exploits in vulnerable applications!
