Posted by   Martijn Grooten on   May 17, 2017

VB2016 paper: Uncovering the secrets of malvertising

Posted by   Martijn Grooten on   May 10, 2017

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. Today, we publish a paper presented at VB2016 in Denver by Malwarebytes researchers Jérôme Segura and Chris Boyd, in which they look at the advertising ecosystem, how it is used, and at what techniques are being utilised to spread malware

Posted by   Martijn Grooten on   Apr 25, 2017
