Cybercrime-as-a-Service (CaaS)

What is Cybercrime-as-a-Service (CaaS)?

Cybercrime-as-a-Service (CaaS)An underground service model in which specialised criminal vendors sell tooling, infrastructure, or expertise so customers can run cyber attacks without building capabilities themselves.


Cybercrime-as-a-Service (CaaS) refers to the wider economy that has industrialised attacks. Sub-categories include Ransomware-as-a-Service (RaaS), Phishing-as-a-Service, Malware-as-a-Service, DDoS booters and stressers, Initial Access Brokers, infostealer log marketplaces (Genesis Market, RussianMarket, 2easy), bulletproof hosting, residential proxy networks, money muling, and cash-out services. Payment is usually in cryptocurrency, and many services adopt SaaS-like features such as web dashboards, support tickets, and revenue sharing. CaaS lowers the technical barrier for low-skill actors and gives experienced groups specialisation gains. Disruption relies on coordinated law-enforcement actions, sanctions, infrastructure takedowns, and cryptocurrency tracing.
