Actionable Threat Intel (III) - Introducing the definitive YARA editor

VirusTotal introduces a reengineered YARA editor integrated with Livehunt and Retrohunt, adding syntax coloring, auto-complete, rule templates, and a testing playground to validate rules against IoCs; the vt module expands YARA beyond file content to metadata and behavior (e.g., ITW domains, sandbox DNS lookups) for more precise detections and streamlined notifications via IoC Stream, with an example file rule provided and further vt improvements forthcoming.
