First line of browser defence: AdBlockers


There is always going to be an argument for not using an adblocker, and it is that content cannot always be free – support through ad revenue or pony up for a subscription. However, so many advertising networks are now permitting malvertising ads to slip onto their servers that is up to consumers to run defensive systems to prevent attack. Malware running with these ads is becoming more sophisticated and more painful, with ransomware becoming even more common, year on year, so defending your systems is a must.

Some sites will respond to your use of an adblocker, either by asking you not to use one, or in some instances, actually prohibiting you from accessing the content. There does need to be an ongoing and urgent discussion about publishers running malicious ads on their site and whose responsibility it is when a visitorĀ“s computer is infected. The advertising networks need to be forced into reviewing their ads much more carefully, and publishers need to make this clear to the ad networks on behalf of their site visitors.

In the meantime, it is down to you to protect your computer and devices from intrusion by malvertising and trackers.

There are many adblockers (such as AdBlock Plus) and there are also now secure browsers (and add ons) such as Ghostery, Privacy Badger and HTTPS Everywhere. For Firefox users, it is a good idea to run NoScript as this will prevent any malicious scripts from running on sites you visit.

A further line of defence is to browse from within a VM (Virtual Machine), such as VirtualBox by Oracle. Many malware suites will not operate in this environment because it is the most often used by security researchers to analyse malware and capture the offenders.
