The Architects of Evasion: a Crypters Threat Landscape

This Sekoia TDR report examines the crypter ecosystem and the growing Crypter-as-a-Service market, explaining crypter types (scantime vs runtime), stub categories (public, private, melt), and FUD concepts; it documents open-source, private and subscription offerings, marketplaces and pricing, outlines the typical service workflow, and assesses how crypters enable widespread malware delivery (RATs, stealers, ransomware) while complicating detection and attribution.
