Uncovering The Secrets Of Malvertising

Friday 7 October 11:30 - 12:00, Red room

Jérôme Segura (Malwarebytes)

Malicious advertising, A.K.A. malvertising, has evolved tremendously over the past few years to take a central place in some of today's largest web-based attacks. It is by far the tool of choice for attackers to reach the masses but also to target them with infinite precision and deliver such payloads as ransomware.

The complexity and layered structure of the ad industry has provided the perfect environment for rogue actors to game the system and create long lasting campaigns that go almost unnoticed. Indeed, by using a combination of social engineering and technical tricks, fraudulent advertisers are able to enter ad platforms and hide their malicious payloads so that traditional scanners are rendered useless.

In this paper, we will provide an overview of the ad industry's core concepts (programmatic, RTB, CPM) that are necessary to understand how and why online criminals are able to leverage the system to their advantage. We will also look into how rogue advertisers are able to defeat security screening both by creating fake identities and deploying advanced techniques to conceal malicious code from prying eyes.

While the debate about ad blockers rages, malvertising will continue to make headlines for the foreseeable future and this is why it is important to stay up to speed with its latest practices.
