In July 2016, we worked with @kafeine of Proofpoint to help bring down the AdGholas malvertising campaign. This campaign started operating in 2015, which affected a million users per day during its peak before it was shut down earlier this year. It used the Angler and Neutrino exploit kits to attack victims. It also used steganography to hide malicious code within a picture.
In the process of working on this campaign, we found and analyzed an information disclosure vulnerability in both Internet Explorer and Microsoft Edge. We worked with Microsoft to address this flaw, named as CVE-2016-3351. Previously considered as a zero-day vulnerability, this issue was fixed in MS16-104 for Internet Explorer and MS16-105 for Edge, which was released though a patch earlier this week.
