In this blog, we discuss Adobe Extensible Metadata Platform (XMP) identifiers and how they can be used as both pivot and detection anchors. Defined as a standard for mapping graphical asset relationships, XMP allows for tracking of both parent-child relationships and individual revisions. There are three categories of identifiers: original document, document, and instance. Generally, XMP data is stored in XML format, updated on save/copy, and embedded within the graphical asset. This last tenet is critical to our needs as we'll be tracking the usage and re-usage of both malicious and benign graphics within common Microsoft and Adobe document lures.

InQuest provides an automated platform for SOC hunter that includes powerful means for inspecting files to detect the presence of malicious code. The platform ingests network data and then goes through a variety of analytic functions resulting in an effective risk score. Check out this interview between Ed Amoroso of Tag Cyber and Pedram Amini, our CTO.

Since YARA rule creation is a highly valuable skill set we approach the lessons slowly, think of "baby steps" from the movie "What About Bob?" as the approach. In keeping the spirit of the process, we feel that the next natural step to take is to learn about the different components that make up the rules and focus on how they are constructed.

In this blog, we take a subtle dive into memory analysis using Volatility and the memory analysis methodology. For those unfamiliar with the tool, The Volatility Framework is a completely open collection of tools, implemented in Python for the extraction of digital artifacts from volatile memory (RAM) samples. The extraction techniques are performed completely independent of the system under investigation but offer visibility into the runtime state of the system. The framework is intended to introduce people to the techniques and complexities associated with extracting digital artifacts from volatile memory samples and provide a platform for further work into this exciting area of research.

InQuest has just released a new analysis suite for the researcher and hobbyist. Welcome to InQuest Labs! Our CTO, Pedram Amini, presented Worm Charming: Harvesting Malware Lures for Fun and Profit at Blackhat USA 2019. During this talk, Pedram detailed the harvesting mechanism that drives the DFI portion of InQuest Labs. Capable of ingesting malware at scale, samples are fed through a lightweight and less featured version of Deep File Inspection to extract embedded logic, semantic content, metadata, and IOCs such as URLs, domains, IPs, e-mails, and file names.
