What is Malvertising? Best practices for avoiding novel threats online By Tom McVey, Senior Sales Engineer EMEA, Menlo Security Artificial intelligence has transformed digital marketing. From tracking customer conversations to measuring engagement with content, it’s a technology that’s enabling organisations to unlock incremental competitive advantages through productivity improvements, data-informed service enhancements, and enhanced customer interactions. However, there are two sides to every coin. Research conducted by CensusWide for Menlo Security reveals that one in three UK consumers believe that over half of all advertisements on websites or social media sites are generated by AI. The merits of AI in marketing and advertising are clear – it’s an undoubtedly useful resource. Yet it also opens up opportunities for malicious actors.

With the increasing use of AI in digital advertising, we at Menlo anticipate a major spike in ‘malvertising’ due to the rise in convincing fake ads created by AI tools like ChatGPT and image generators such as Midjourney and DALLE. What is malvertising? Malvertising is a form of highly evasive threat where malware is embedded into online or social media ads. Malvertising can be particularly tricky to detect for both internet users and publishers, with malicious ads typically serving consumers through legitimate advertising networks; all internet users encountering them are at risk of infection. Not only is malvertising novel, it's typically complex, and usually comprises several rungs in the attack chain. Attackers will usually begin by breaching a third-party server to inject malicious code within a digital advert, such as a banner advert, or video. If clicked by a website visitor, the corrupted code will lead to the installation of malware on the user’s endpoint device or direct a user to a malicious website. Indeed, some advertising attacks involve the use of exploit kits – created with the intention of surveying a system to then identify and exploit vulnerabilities. And, if installed, malware can wreak untold damage. Threat actors may delete, modify, or encrypt data. Further, malware may be used to corrupt files, redirect internet traffic, monitor user activity, steal data or develop backdoor access routes to a system. Awareness of malvertising is currently low Given this is a relatively novel and innovative attack method, awareness of the threats of malvertising remains low at present. In our survey conducted with CensusWide, we found that while seven in ten consumers say they currently click on advertisements on the internet ‘to some extent’, the vast majority (70%) of respondents simply didn’t know they can be infected with malware by clicking on a brand logo. By comparison, almost three-quarters (73%) understand they can be infected by malware hidden in an email link. The research also revealed that around half (48%) are unaware they can be infected via a social media ad, while 40% didn’t know they can be infected by clicking on pop-ups and banners. Furthermore only 32% wouldn’t trust any website not to contain malvertising. These statistics are concerning. Indeed, it’s estimated that approximately one out of 100 online ads is currently malicious, and we now expect this to rise even further as more AI tools and software become increasingly available and easy to use.
