Malvertizing, or malicious advertizing, is a cyber-threat that involves disguising spam code into online advertizements that seem to be legitimate. When a user hovers or clicks on any of these ads, it leads to downloading malicious software that can damage data, steal confidential information or even get complete remote access of the infected computer. Malvertizing attempts to exploit the unpatched software vulnerabilities in a computer without any need to compel the user to visit a malicious website.
How Does Malvertizing Work?
Malvertizements can appear on a website in any of the following ways:
- Legitimate Ads: The cybercriminal initially places a number of malware free advertizements on a credible website that allows third party ads. Eventually, he may inject a malicious code into the advertizement to infect maximum computers before it is banned or removed.
- Pop-Ups: Pop-ups can infect a user’s computer the moment the ad appears on the web page. In some cases, the malware may also be installed when the views clicks on ‘X’ to close the pop-up.
How To Protect Against Malvertizing?
- Disable Auto Play For Plug-ins: When you choose auto play for plug-ins, all Java and Flash elements will automatically run when you visit a web page. As most malvertizing attacks involve the use of malicious plug-ins, make sure you have complete control over the ones that you need to run.
- Remove Unused Plug-Ins: You should disable or uninstall all the browser plug-ins that you do not use, including Java. This will reduce the probability of a malvertizing attack by limiting the number of vulnerable software that can be exploited by the cybercriminals.
- Update Your Web Browser: Your web browser should be regularly updated to fix any security flaws. You can enable automatic updates to keep your browser protected against malvertizing attacks. If you have a plug-in installed, make sure they are frequently updated with the latest versions.
- Stay Informed: You should always be cautious of pop-ups that claim to remove malware or increase the speed of your computer. Do not click on any of these links as they may inject a malicious code or download spam software to your computer. Anti-virus, anti-malware software and browser toolbars should also not be installed through an advertizement or pop-up link.
