Why Real Time Threat Intelligence Isn’t Enough

Detecting security threats is difficult work, now more so than ever. Our threat intelligence tools are playing catch-up with increasingly sophisticated attack vectors, including polymorphic malware, quick-turn domains and other turn-on-a-dime attack tactics.

Building Your First Incident Response Policy: A Practical Guide for Beginners

It only makes sense to assume that sooner or later your company will have to handle a security incident and the subsequent recovery from any damage caused.

Creating an incident response policy before an incident occurs can help you minimize risk and ensure that you and your team are prepared. By planning your response ahead of time, you will be able to respond faster and more efficiently, and possibly even prevent additional damage from occurring.

Demisto & Uptycs: Orchestrating Incident Response Activities

Orchestration engines such as Demisto give security professionals the freedom to integrate multiple services into coordinated, automated workflows.  Simple REST APIs allow the transfer of data from one application or service to another in a reliable, straight-forward manner. With the appropriate data sources, users are enabled to create workflows and reports for incident investigation and response. In removing the human element, orchestration engines can improve the overall efficiency and consistency of incident response, while freeing up time for other tasks.

Uptycs leverages the open-source osquery agent in order to acquire real-time data about nearly any facet of your infrastructure (more about osquery here). This data is streamed, aggregated, and stored in the Uptycs backend and then made accessible via our API, allowing the integration of Uptycs data with other services.

Hardening defenses with MITRE ATT&CK and osquery: Lessons from Singapore Health Breach

There's a big disconnect between best practice frameworks and the real-life nitty gritty. Many of these frameworks broadly approach the overarching principles that a robust security program should encompass and why these principles are important; however, they don't usually say specifically what kind of attacker behavior a defender should anticipate when building their security programs, nor do they detail how an attacker would work to thwart those vaulted best practices. Often, that's left up to the security practitioner to suss out themselves in their copious spare time.

Detecting Malicious Packages in Repositories like PyPI: Using Osquery for Complete Software Inventory

Many systems make installing 3rd party software incredibly convenient; from packaging systems and well loved Linux distribution tools like Debian Apt to app stores and per-language repositories. Users are also often allowed to install browser extensions or plugins, which come from their own “store” and are just another type of software. For these reasons, and without forgetting containers, maintaining a software inventory that allows you to identify dangerous packages has become harder to do, but more critical to accomplish.

Threat Hunting with Osquery: 5 macOS Malware Techniques & How to Find Them

This previous blog post explored ways to use osquery for macOS malware analysis. Using the same methodology introduced there, we analyzed five additional macOS malware variants and recorded their behavior to understand the techniques they used. Below, you’ll find the techniques used by Calisto, Dummy, HiddenLotus, LamePyre and WireLurker. Read on to explore how to translate the techniques used by these malware into queries you can run to hunt for the active presence or historical artifacts using osquery.
