October 2023: back to Positive Technologies, Vulristics updates, Linux Patch Wednesday, Microsoft Patch Tuesday, PhysTech VM lecture. Hello everyone! October was an interesting and busy month for me. I started a new job, worked on my open source Vulristics project, and analyzed vulnerabilities using it. Especially Linux vulnerabilities as part of my new Linux Patch Wednesday project. And, of course, analyzed Microsoft Patch Tuesday as well. In addition, at the end of October I was a guest lecturer at MIPT/PhysTech university. But first thing first.

Leave a reply

Vulnerability Management at Tinkoff Fintech School. In the last three weeks, I participated in Tinkoff Fintech School – educational program for university students. Together with my colleagues, we prepared a three-month practical Information Security course: 1 lecture per week with tests and home tasks.

Each lecture is given by a member of our security team, specialized in one of the following modules: Vulnerability Management, Application Security, Infrastructure Security, Network Security, Virtualization Security, Banking Systems Security, Blue & Red-teaming, etc.

Sending FireEye HX data to Splunk

Sending FireEye HX data to Splunk. FireEye HX is an agent-based Endpoint Protection solution. Something like an antivirus, but focused on Advanced Persistent Threats (APT). It has an appliance with GUI where you can manage the agents and see information about detected security incidents.

As with any agent-based solution, it’s necessary to ensure that the agents are installed on every supported host in your network. You may also want to analyze the alerts automatically. And for both purposes you can use Splunk. Let’s see how to do it. 😉

Note, everything bellow is for FireEye Endpoint Security (HX) 4.0.6 and Splunk 7.0.2. If you use some other version, the things may be quite different.

The main idea is following. We should present FireEye hosts and alerts data in JSON format, add some mandatory fields ans send this packages to Splunk using HTTP Event connector. Then we can process it in Splunk like I’ve shown in “How to correlate different events in Splunk and make dashboards“.

Vulchain scan workflow and search queries

Vulchain scan workflow and search queries. This post will be about my Vulnerability Scanner project – Vulchain. Recently I’ve spent couple of my weekends almost exclusively on coding: refactoring the scan engine, creating API and GUI.

Vulchain scan workflow and search queries

I was doing it because of the conferences, where I will be speaking soon:

Pretty intense schedule for a guy who spends most of his time in PyCharm and Linux console. 😉 Very excited! So, it seemed right to add a couple of slides about my project and show that something is already working.

Burp Suite Free Edition and NTLM authentication in ASP.net applications

Burp Suite Free Edition and NTLM authentication in ASP.net applications. As you know, Burp Suit is a scanner for advanced Web Application Security researchers. However, the free version of Burp is more like Firebug analogue, but much more functional.

Let’s see how to install it and use for website analysis. This analysis may be necessary to find vulnerabilities or somehow automate the work with the site. Let’s take, for example, ASP.net applications with NTLM-authorization, which is rather unpleasant to analyze.

Go to the site https://portswigger.net/burp/freedownload and download burp installer as a bash script:
