Using eval to Calculate, Appraise, Classify, Estimate & Threat Hunt

Nov 28, 2023 By Tamara Chacon In Splunk
I hope you're all enjoying this series on Hunting with Splunk as much as we enjoy bringing it to you. This article discusses a foundational capability within Splunk — the eval command. If I had to pick a couple of Splunk commands that I would want to be stuck on a desert island with, the eval command is up there right next to stats and sort. (Part of our Threat Hunting with Splunk series, this article was originally written by John Stoner. We’ve updated it recently to maximize your value.)

Using RegEx for Threat Hunting (It's Not Gibberish, We Promise!)

Nov 20, 2023 By Tamara Chacon In Splunk
Known as RegEx (or gibberish for the uninitiated), Regular Expressions is a compact language that allows security analysts to define a pattern in text. When working with ASCII data and trying to find something buried in a log, regex is invaluable. But writing regular expressions can be hard. There are lots of resources to assist you: “But stop,” you say, “Splunk uses fields! Why should I spend time learning Regular Expressions?”

How are IT leaders and their MSPs approaching threat hunting?

Nov 7, 2023 By Iratxe Vazquez In WatchGuard

Companies are increasingly aware of the importance of creating detection and hunting capacities that help to keep their business’s future from being put at risk. The popularity of threat-hunting services is a consequence of detecting ever more persistent attacks, which also last longer and longer. On top of this, cybercriminals also have ever more tactics to avoid traditional defense measures.

Creating a Threat Hunting Lab in Graylog

Oct 10, 2023 By David Elgut In Graylog
When I was looking to break into the cybersecurity industry, I found myself overwhelmed with the sheer amount of content to learn and try. So much of the content, you had to purchase certain things, or it was way too complicated for me to understand at the time. Today, I wanted to break down create an easy walk-through on how to set up a functional threat hunting lab.

Why Every Company Should Include Threat Intelligence in Their Cybersecurity Strategy

Sep 29, 2023 By Chris Jacob, Global VP of Threat Intelligence Engineering In ThreatQuotient
In the fast-evolving digital landscape, the prevalence of cyber threats has become a stark reality for businesses and individuals. While essential, conventional cybersecurity measures are often reactive and inadequate against sophisticated attacks. This is where Cyber Threat Intelligence (CTI) emerges as a proactive and complementary approach to cybersecurity. Utilising CTI helps organisations to protect their systems from potential hazards. It provides a way to cut through the noise and focus on threats relevant to that specific company and industry.

Next-Level Threat Hunting: Shift Your SIEM from Reactive to Proactive

Sep 28, 2023 By The Graylog Team In Graylog
Threat hunting is proactively identifying and thwarting unusual network activity that could indicate an attempted security breach. It’s a historically manual activity, making it time-intensive and arduous. It’s no wonder, then, why most organizations don’t have the time, budget, or resources to undertake it effectively…if at all.

Using metadata & tstats for Threat Hunting

Sep 18, 2023 By Tamara Chacon In Splunk
So you want to hunt, eh? Well my young padwa…hold on. As a Splunk Jedi once told me, you have to first go slow to go fast. What do I mean by that? Well, if you rush into threat hunting and start slinging SPL indiscriminately, you risk creating gaps in your investigation. What gaps might those be? As a wise man once said, Know thy network. Actually — in this case — know your network and hosts.

Using stats, eventstats & streamstats for Threat Hunting...Stat!

Sep 18, 2023 By Tamara Chacon In Splunk
If you have spent any time searching in Splunk, you have likely done at least one search using the stats command. I won’t belabor the point: stats is a crucial capability in the context of threat hunting — it would be a crime to not talk about it in this series. When focusing on data sets of interest, it's very easy to use the stats command to perform calculations on any of the returned field values to derive additional information.

Key Threat Hunting Deliverables with PEAK

Aug 25, 2023 By Sydney Marrone In Splunk
When most people think of threat hunting, they think of uncovering unknown threats. Would you believe me if I told you that is only ONE of many (better) reasons to show value with threat hunting? The PEAK Threat Hunting Framework incorporates three distinct hunt types: hypothesis-driven, baseline and model-assisted threat hunts. Each hunt type follows a three-stage process: Prepare, Execute, and Act.
