Examining Shellcode in a Debugger through Control of the Instruction Pointer

During the examination of malicious files, you might encounter shellcode that will be critical to your understanding of the adversary's intentions or capabilities. One way to examine this malicious code is to execute it using a debugger after setting up the runtime environment to allow the shellcode to achieve its full potential. In such circumstances, … Continue reading Examining Shellcode in a Debugger through Control of the Instruction Pointer


Analyzing Shellcode Extracted from Malicious RTF Documents

During the analysis of malicious documents designed to exploit vulnerabilities in the programs which load them (thereby allowing the running of arbitrary code), it is often desirable to review any identified shellcode in a debugger. This allows an increased level of control and flexibility during the discovery of it's capabilities and how it implements the … Continue reading Analyzing Shellcode Extracted from Malicious RTF Documents


Running Malware Analysis Apps as Docker Containers

A new REMnux project initiative provides Docker images of Linux applications useful for malware analysis to offer investigators easier access to malware forensics tools. Docker is a platform for packaging, running and managing applications as "containers," as a lightweight alternative to full virtualization. Several application images are available as of this writing, and you can contribute your own as a way of experimenting with Docker and sharing with the community. Continue reading Running Malware Analysis Apps as Docker Containers

Kerberos in the Crosshairs: Golden Tickets, Silver Tickets, MITM, and More

It's been a rough year for Microsoft's Kerberos implementation. The culmination was last week when Microsoft announced critical vulnerability MS14-068. In short, this vulnerability allows any authenticated user to elevate their privileges to domain admin rights. The issues discussed in this article are not directly related this bug. Instead we'll focus on design and implementation … Continue reading Kerberos in the Crosshairs: Golden Tickets, Silver Tickets, MITM, and More
