# Fast Velocity Class

A velocity classification where attack progression occurs within minutes. Typical threat clusters: #3 (Exploiting Client), #2 (Exploiting Server). Control strategy requires automated containment and EDR blocking, as human analyst response times are insufficient. Example: Drive-by downloads, browser exploits, RCE exploitation.
