In the ever-evolving landscape of cybersecurity threats, one name that consistently surfaces as a force to be reckoned with is "PlugX." This covert and insidious malware has left a trail of digital intrigue, combining advanced features with a knack for eluding detection. Its history is interwoven with cyber espionage, targeted attacks, and a continuous cat-and-mouse game with security experts (1)(2).

An important piece of cybersecurity, SOAR solutions provide a single location for you to observe, understand, and decide how to respond to security incidents. Short for security orchestration, automation and response, true SOAR solutions are operational tools that can be very flexible and powerful, useful even beyond security use cases. In this article, we’ll explore what SOAR is, why it’s important for enterprises and how you can get the most value from your SOAR solution.

When hunting, advanced security Splunkers use apps. Specifically, three related apps from an incredibly generous man named Cedric Le Roux! (You can guess from the name that yes, he's French.) And frankly, you probably only know one: URL Toolbox. One of the most popular Splunk security apps of all time, URL Toolbox’s URL parsing capabilities have been leveraged by thousands who want to separate subdomain, domain, and top level domain (TLD) from a URL.

As defenders, we need to keep pace with all kinds of different aspects of the attack surface. For Windows, the attack surface seems to just continue beyond our grasp every way we look, especially when we start to dig into trust and the registry. As previously outlined in the Splunk Threat Research Team’s blog, "From Registry With Love: Malware Registry Abuses," the vast methods used by adversaries to persist and abuse the Windows registry goes deep.

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.)

Cybercriminals and threat actors use multiple vectors to infiltrate your IT network. They employ a series of coordinated steps as they… Impactful cyberattacks today are no longer executed as a simple virus with self-mutation capabilities, especially when many organizations rely on AI-enabled threat detection capabilities. They’re a lot more sophisticated.

In organizational risk management, Risk Tolerance and Risk Appetite are two fundamental concepts. These concepts are applied in areas such as business investing, decision making, cybersecurity risk management, and overall finance. While these concepts complement each other, they do have different meanings. A simple distinction is this: And there’s a bit more to it.

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?”
