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


Using Sysinternals System Monitor (Sysmon) in a Malware Analysis Lab

System Monitor (Sysmon) is a new tool from Microsoft, designed to run in the Windows system's background, logging details related to process creation, network connections, and changes to file creation time. This information can assist in troubleshooting and forensic analysis of the host where the tool was installed prior to the incident that's being investigated. This article explores the role that System Monitor might play in a malware analysis lab, possibly supplementing tools such as Process Monitor. Continue reading Using Sysinternals System Monitor (Sysmon) in a Malware Analysis Lab


Hibernation Slack: Unallocated Data from the Deep Past

Hi Folks, I was recently doing some forensic research on a laptop which had been formatted and factory-reinstalled (using the preinstalled HPA partition it shipped with), and then used normally by another user for six months prior to collection. I wasn't really expecting to be able to recover much of anything from before the format, … Continue reading Hibernation Slack: Unallocated Data from the Deep Past
