A detailed report by Cisco on how Angler EK works

概要

Angler is an exploitation machine, continuing to compromise users at a high rate for a long time. This is due largely to how effective and innovative Angler has been. Whether it is Domain Shadowing, 302 Cushioning, Encrypted Payloads, or rapid exploit deployment, Angler has dominated 2015, as predicted in last years Annual Security Report. While conducting this research Talos was able to obtain information about hosts serving Angler. We now have a good approximation around Angler’s revenue stream. By analyzing the behavior of just one node delivering Angler as well as a server monitoring these systems, Talos can reliably say that one threat actor was responsible for up to half of the Angler activity that we’ve observed globally. This malicious network generates approximately more than $30 million annually, which we will cover in detail later.
