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

Posted by Guillaume Ross on 7/24/19 12:03 PM

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.

Remote Desktop Vulnerabilities: Identifying the Exposure and Patch Using Osquery

Posted by Guillaume Ross on 5/15/19 10:13 AM

[Updated June 5th] Patching for the CVE (CVE-2019-0708) vulnerability (referred to as BlueKeep) appears to have been slow, according to Rob Graham among others. One security expert, Ryan McGeehan (@Magoo), with experience in modeling vulnerability exploit probability and has done just that with the BlueKeep security flaw. 

His concerning summary concludes:

"Chances are about even ( 47.62%)  for “in the wild” BlueKeep exploitation to be observed between now and end of June."

Follow the outline below to check your exposure using osquery.

Microsoft released an important patch to the remotely exploitable Remote Desktop Services (RDS) vulnerability. This vulnerability does not require any authentication and allows an attacker to run code remotely. Expect public exploits to start appearing soon.

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

Posted by Amit Malik on 5/2/19 9:40 AM

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.

The First Curated Osquery Resource Hub

Posted by Amber Picotte on 4/25/19 1:20 PM

Progress in open source projects thrives on the sharing of information. Yet even with the best of intentions, much of the learning can still be considered tribal knowledge, traded between small groups of closely connected individuals. While, the osquery project certainly isn’t immune to this, the community has absolutely benefited from a passionate and growing base of users, developers, contributors and tinkerers that are dedicated to documenting and sharing what they’ve learned.

Mac Malware Analysis Using Osquery

Posted by Amit Malik on 3/19/19 9:01 AM

Osquery, at its most basic level, is an operating system instrumentation framework that exposes the OS as a SQL database. SQL queries can be run to view information about the systems similar to any SQL database, providing a unified cross platform framework (i.e. endpoints running on multiple operating systems can be queried using the industry standard database language: SQL. This structured approach for collecting and accessing data introduces great flexibility, making it useful for multiple purposes. For example, queries can be constructed to audit infrastructure for compliance, vulnerabilities, malware analysis and intrusion detection, etc. Data collected by osquery can be useful to anybody from IT support teams to CSIRTs. However, in this blog post we’ll narrow our focus and explore how to use osquery specifically for macOS malware analysis (though the methodologies discussed are the same for Windows and Linux operating systems).
