Cyber Security Operations
I have written this guide a few times in the past, but here is a revised version with some notable inclusions based on more recent experiences with Cuckoo. I have some Github repositories too which aim to expedite the process, but have a read nonetheless and see just how easy and quick it can be…
Every few months, StrangeBee puts out an update to TheHive (Security Incident Response Platform). This month they have added Elasticsearch as an index engine to alleviate issues with using Cassandra, and they have integrated support for MISP galaxies as well!
Now Incident Responders using TheHive can export IOCs and Galaxy assignment directly from TheHive to MISP.

Static analysis for me has become more fun with the inclusion of Assemblyline into my arsenal. But the lack of integration between other elements of my FOSS SOC stack was concerning.
In this post I detail not only how to write a Cortex Analyzer, but also how to integrate with other appliances with that analyzer.

Since the last write up I published on TheHive, there have been some significant changes and updates to TheHive. So for this post I will be walking through the installation and deployment of TheHive4 (4.0.5) and the connection to MISP, Cortex and enabling Webhooks.

Cuckoo’s dynamic malware analysis platform is pretty good out of the box. But how can we scale it to allow parallel processing of samples, particuarly where Cuckoo is part of a process driven analysis workflow? In this article we discuss parallel processing for Cuckoo with 5x Windows 7 VMs.
Cuckoo is an automated dynamic malware analysis platform which allows for the analysis of submitted artefacts within a range of custom configured guest operating systems.
Analysis environments may be created for Windows, Linux, MacOS and Android, with all manner of filetypes able to be analyzed through the Cuckoo platform. Including, executables, office documents, pdf files, emails, and even hands-on execution of malware with network connections able to be routed through Tor.

VirusTotal is a subsidiary of Alphabet Inc. (which is also the parent company of Google). The service offers static and dynamic artefact analysis through a combination of free and paid tiers of access, as well as access to broader intelligence harvested from submissions and their own honeypots.
The Virustotal service is quite popular amongst the Information Security profession in performing quick analysis of artefacts, however there are some drawbacks and other aspects to consider before implementing VirusTotal as part of your DFIR stack of tools.

As part of my final Masters degree research component I have been collecting data from honeypots which I have seeded around the globe. The objective being to distil this data in to organisational threat data based on a fictitious business.
Part of the complication I am going to start facing, is how to how Elasticsearch and Kibana to find specific information for me from this live data set.
Previously I have indicated that a data set exists which was produced by the Canadian Institute for Cybersecurity, called IDS 2018, which contains Windows Event Logs and PCAP files relating to a set of simulated attacks generated for the purposes of teaching people how to hunt within similar datasets.
Here I will be discussing the deployment, configuration and interaction with this data set to achieve the outcome required.

So whilst playing through an element of Kringlecon 2019 I came across a task which didn’t really suit my Christmas challenge of going to Linux full-time. One such challenge involved a Windows Event Log file with no ready access to a Linux derivitive of Event Viewer. My Kali laptop for my Christmas challenge was already…
Sometimes there is a need to analyse files in a live environment where their composition and provenance may not be entirely certain. For the most part we can try to reply on virus detection and heuristics to detect potentially malicious files, but what about those files which have not yet been identified, or have been specifically crafted for your organisation as a targeted attack?
Note: I have updated this article to reflect the current installation requirements for Cuckoo on Ubuntu 18.04 (as at 22nd Feb 2021).
