Deploying osquery for Windows Using GPO (Group Policy Objects)

Deploying osquery for Windows Using GPO (Group Policy Objects)

We are asked quite often if deploying the osquery agent is possible via Windows Group Policy Objects (GPOs). 

Checking MDS/Zombieload Mitigations on macOS with Osquery

Checking MDS/Zombieload Mitigations on macOS with Osquery

As a part of a pretty crazy week (Microsoft/RDS, Apple/Mojave/High Sierra, Adobe Acrobat/ Flash Player) when it comes to security updates, some new speculative execution vulnerabilities were disclosed and fixed.

Remote Desktop Vulnerabilities: Identifying the Exposure and Patch Using Osquery

Remote Desktop Vulnerabilities: Identifying the Exposure and Patch Using Osquery

[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.

The First Curated Osquery Resource Hub

The First Curated Osquery Resource Hub

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

Mac Malware Analysis Using Osquery

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).

Detecting Dirty_Sock with Osquery - A Snapd Privilege Escalation Vulnerability

Detecting Dirty_Sock with Osquery - A Snapd Privilege Escalation Vulnerability

You may have heard about “Dirty Sock”, a recently discovered vulnerability targeting snapd sockets, playing on the name of a previous vulnerability called “Dirty Cow”. Snapd allows for the execution of packaged snaps, which are a mechanism to distribute and update applications in a standard format.
