![]() An example of the former: > osqueryi -extension build/external/extension_trailofbits/trailofbits_osquery_extensions.ext To quickly test an extension, you can either start it from the osqueryi shell, or launch it manually and wait for it to connect to the running osquery instance. Windows: tests are not yet supported on Windows. MacOS or Linux: once osquery has been built with tests enabled ( i.e., with -DOSQUERY_BUILD_TESTS=ON CMake option), enter the build folder and run the following command: cmake -build. Windows: osquery\build\external\Release\trailofbits_osquery_.macOS: osquery/build/external/extension_trailofbits/trailofbits_osquery_extensions.ext.Linux: osquery/build/external/extension_trailofbits/trailofbits_osquery_extensions.ext (except network_monitor, which is in osquery/build/external/extension_trailofbits/extensions/network_monitor/network_monitor.ext).This is where the extension should be available once it has been built: Note: The network_monitor extension stands alone as a separate executable, because it's a network listener that drops its own privileges at runtime. $env:TRAILOFBITS_EXTENSIONS_TO_BUILD = "windows_sync_objects,fwctl " Here are example steps for each platform: Linux/macOS Resume following the osquery build guide to build osquery and now the extensions too.Symlink the osquery-extensions folder into osquery/external/extension_trailofbits. ![]() To install pre-requisites and build but stop just before the configure step. The instructions below are only necessary for those interested in building from source. Note: the releases page has download links for our extensions. Provided an event driven table that contains entries from the unified system log on MacOS.ĪPI updates on macOS 10.15 permit moving this functionality into core osquery. Uses libpcap and Pcap to capture and parse network requests. ![]() Provides an event-based table that lists DNS requests performed by the endpoint. Provides a superset of the information supplied by the default iptables table Provides a table that reports MDM enrollment status. Provides osquery with the ability of listing and locking Windows synchronization objects (mutants, events, semaphores). Provides osquery with NTFS-specific forensic information for incident responders. Provides osquery with the ability to view and manage the OS-native firewall rules and /etc/hosts file (port and host blocking). Check DENY events and manage the whitelist/blacklist rules. Integrates osquery with the Santa application whitelisting solution. Integrates osquery with the Duo Labs EFIgy API to determine if the EFI firmware on your Mac fleet is up-to-date. To learn more about osquery extensions development and why developing outside of 'core' is encouraged for demonstrating new use cases or novel functionality, view our talk ( slides, video) from Quer圜on 2018. Trail of Bits has developed extensions to provide tables that can manage service configurations as well as view them, or that can cross-check information on the host with external third-party services. In extensions, we can add capabilities that go beyond what would be possible in osquery core. Here, we use it to demonstrate other pioneering use cases of osquery. The extensions interface allows organizations to implement proprietary detection methods, or address their individual needs. If you would like to sponsor the development of an extension, please contact us.Įxtensions are a type of osquery add-on that can be loaded at runtime to provide new virtual tables. This repository includes osquery extensions developed and maintained by Trail of Bits.
