Alienvault: The AlienVault agent is based on Osquery.Some of the tools (open-source and commercial) that utilize Osquery are listed below. Many well-known companies, besides Facebook, either use Osquery, utilize osquery within their tools, and/or look for individuals who know Osquery.Īs of today (March 2021), Github and AT&T seek individuals who have experience with Osquery. Osquery can be installed on multiple platforms: Windows, Linux, macOS, and FreeBSD. With Osquery, Security Analysts, Incident Responders, Threat Hunters, etc., can query an endpoint (or multiple endpoints) using SQL syntax. Select processes.pid, ername, processes.path from processes LEFT JOIN users ON processes.uid = users.uid WHERE processes.Osquery is an open-source tool created by Facebook. Select path, size, from file where path like ‘C:\Users\%%’ and mtime > (select local_time from time) - 100 and filename != ‘.’ Select processes.name, process_open_sockets.remote_address, process_open_sockets.remote_port from process_open_sockets LEFT JOIN processes ON process_open_sockets.pid = processes.pid WHERE process_open_sockets.remote_port != 0 AND processes.name != ‘’ Select time, script_text from powershell_events “Malware Analysis using Osquery | Part 2” Appendix

In the next posts of this blog series, we will see other malware families and explore how to detect activity like system persistence and many others techniques. Here is an example of how we detected Emotet infection on an analysis system using OTX Endpoint Threat Hunter. Get started with OTX Endpoint Threat Hunter Free: OTX Endpoint Threat Hunter allows anyone to determine if their endpoints are infected with the latest malware or other threats by manually scanning their endpoints for the presence of indicators of compromise (IoCs) that are catalogued in OTX.

In April, AlienVault introduced the Endpoint Threat Hunter - a free threat-scanning service in Open Threat Exchange® (OTX™) based on the AlienVault Agent. Try it for yourself in the USM Anywhere Online Demo. This allows USM Anywhere to deliver endpoint detection and response (EDR), file integrity monitoring (FIM), and rich endpoint telemetry capabilities that are essential for complete and effective threat detection, response, and compliance. In USM Anywhere, the AlienVault Agent enables continuous endpoint monitoring, using the built-in AlienVault threat intelligence to automate endpoint queries and threat detection alongside your other network and cloud security events.
The AlienVault Agent is a lightweight, adaptable endpoint agent based on Osquery and maintained by AlienVault. This can be extremely helpful for investigating security incidents as well as threat hunting activities on your critical assets.ĪlienVault leverages Osquery through the AlienVault Agent to enable threat hunting in both USM Anywhere and the Open Threat Exchange. Osquery allows you to retrieve a wealth of events and useful information from your endpoints. As we have seen, it is possible to analyze malware and extract valuable information using tools like Osquery that give us rich visibility of systems events.
