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

Despite the profitability of ransomware there is a good reason why mining malware is thriving

Though ransomware is far more profitable than using a compromised PC to mine bitcoins, the global distribution of malware means that there are many botnets for which mining is the most efficient way to extract money out of a PC.
