Investigating Threat Alerts with Osquery: Understanding Threat Surface & Risk

The Uptycs Threat Intelligence team is responsible for providing a high quality, curated, and current Threat Intelligence feed to the Uptycs product. In order to deliver the threat feed, the team evaluates every single alert that is seen by our customers, and investigates the alert as feedback into the threat feed curation process. Recently we observed a malicious domain alert from a customer. The out-of-the-box alert description indicated that it belonged to the OSX/Shlayer malware family. We were quickly able to query Uptycs threat intelligence to find that the domain first appeared on February, 2019 and was reported by multiple threat intel sources. Once the threat was validated, we dove into deeper investigation to understand the threat surface and risk. This post walks through the steps and techniques we performed to analyze data that had been collected via osquery, and aggregated in Uptycs.

Hardening defenses with MITRE ATT&CK and osquery: Lessons from Singapore Health Breach

There's a big disconnect between best practice frameworks and the real-life nitty gritty. Many of these frameworks broadly approach the overarching principles that a robust security program should encompass and why these principles are important; however, they don't usually say specifically what kind of attacker behavior a defender should anticipate when building their security programs, nor do they detail how an attacker would work to thwart those vaulted best practices. Often, that's left up to the security practitioner to suss out themselves in their copious spare time.
