In this workshop, attendees will learn how to exploit those nasty stack-based buffer overflow vulnerabilities by applying the theoretical methods taught in this course to hands-on exercises. Exercises will be performed for real world (32-bit) software such as the Foxit Reader Plugin for Firefox, Wireshark, and nginx.

Continue readingAfter our last blogpost regarding Emotet and several other Emotet and Ransomware samples that we encountered, we recently stumbled across a variant belonging to the Gozi, ISFB, Dreambot respectively Ursnif family. In this blogpost, we want to share our insights from the analysis of this malware, whose malware family is mainly known for being a banking trojan that typically tries to infect browser sessions and sniff/redirect data. In particular, we are going to provide details about the first stage Word Document, the embedded JavaScript/XSL document, an in-depth runtime analysis of the downloaded executable, and some details regarding detection.
Also, with this blog post, we are releasing a Rekall plugin called pointerdetector that enumerates all exported functions from all DLLs and searches the memory for any pointer to them (essentially a search for dynamically resolved APIs). This plugin can assist in identifying dynamically resolved APIs and especially memory regions containing DLLs loaded with techniques such as reflective DLL injection. This blog post will contain some examples illustrating the usage of this plugin, as well.
If you are interested in a hands-on analysis of Incidents and malicious files, we are giving another round of our Incident Analysis workshop at Troopers20.
