A benefit of using a threat hunting framework is that it provides actionable, repeatable steps to conduct threat hunting. This is essential as it allows for a systematic approach to identify and mitigate threats effectively. It does not automatically generate incident reports, eliminate false positives, or provide high fidelity threat actor attribution, but rather helps in executing a structured threat hunting process.

A Falcon threat hunting lead typically involves identifying potentially malicious activity by analyzing specific behavioral patterns or indicators within an environment. A query showing process executions of single-letter filenames from temporary directories is indicative of suspicious activities often employed by malware. Hence, this query represents a concrete example of a Falcon threat hunting lead.

The Falcon Detections page will attempt to decode Encoded PowerShell Command line parameters when the -e parameter is present. This parameter is used to denote that the command fragment following it is encoded.

The structured analytic technique that contrasts different hypotheses to determine which is the best leading (prioritized) hypothesis is Analysis of Competing Hypotheses. This method involves considering multiple hypotheses and examining evidence to discount incorrect ones, ultimately identifying the most likely hypothesis.

The SPL (Splunk) field name used to automatically convert Unix times (Epoch) to UTC readable time within the Falcon Event Search is _time. This is because _time is a default field in Splunk that holds timestamp information and automatically interprets Unix epoch time as human-readable time.
