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).

Windows Registry & Osquery: The Easy Way to Ensure Users are Secured

Posted by Guillaume Ross on 1/24/19 10:29 AM

The Windows registry is full of information, and with the proper tools, can be a gold mine for attackers and defenders alike. Attackers look to find specific configurations, credentials, or any information that can help them further attack systems, while defenders can use the registry to ensure that settings are configured as they are expected to. This is something that is not always easy to do with standard tools in Windows, or with the right level of performance. Fortunately, osquery solves that for us.
