Basic Wireshark Skills ( Brad’s MTA Wireshark Tutorials).

How data reduction aids in investigations.

How to pivot into and away from PCAP Analysis (how to use findings for quicker analysis).

Understand the advantages and goals of PCAP Analysis.

This post assumes you have a DFIR Analyst Station ready to analyze the PCAPs from The Case of the Stolen Szechuan Sauce.

Make sure you understand the basic rundown of forensic artifacts. Have you built your DFIR Fort Kickass, yet? How to build a DFIR Analyst Workstation found here. We had to create our own software in order to extract this information from large pcap files.Reading Time: 28 minutes Case 001 PCAP Analysis We also offer a text file containing a description of all the input/output operations that appear in the SMB traffic. In order to refer to this repository please include the link in your paper, cite the repository shared in IEEE dataPort ( here) and/or cite this paper in which the repository is explained in more detail

We will only send you a link to download the full pcap files. This helps us to keep this repository up and include more samples (as it proves that it is interesting for the community).

If you find it useful and you want to download the whole samples, we ask for your e-mail and institution name, in order to keep a record of hoy many people are interested in these files. You can download 10% of the packets from each traffic trace for free. There is a link to an info page for each sample, offering some information about the sample and about the scenario where it ran ('More info' column in the table). There are 94 samples from 32 different ransomware families downloaded from malware-traffic-analysis and hybrid-analysis. This is a repository of PCAP files obtained by executing ransomware binaries and capturing the network traffic created when encrypting a set of files shared from an SMB server.
