- Adblocking software will not block every piece of advertising but can dramatically reduce the attack surface. When choosing a product, however, research whether the product whitelists certain ad providers, as those advertisers will be ‘trusted’ by the adblocking software and permitted to show you their ads.
- When performing normal everyday functions, log in to your system using a non-administrator account. Many drive-by downloads and installers will fail if you don’t have sufficient access rights to install and execute software. In security circles this is called least privileges.
- Avoid using Flash and Java. Uninstall if possible. If you have to run them, make sure to only install and use the most current patched version.
- Maintain your web browser at the current patch level.
- Enable security settings on your browser. For example, “Warn me when sites try to install add-ons” in Firefox.
- Use anti-virus and anti-spyware/anti-malware software, especially ones that can detect potential malicious websites that you are attempting to visit.
Industry also has a vested interest in policing itself, as revenues will decline as more users adopt adblocking software. Additionally, reputable companies will avoid employing advertising networks that have been caught hosting malvertising to avoid damaging their brands. Malvertising is more than just an information security problem for users; it goes to the heart of e-commerce as it threatens people’s ability to access content freely and with minimal risk.
