Inside the Cybercrime‑as‑a‑Service Marketplace: How Crime Kits Are Bought and Sold

A recent arXiv scoping review systematically mapped the Cybercrime‑as‑a‑Service (CaaS) ecosystem, detailing its tiered structure, service categories, and the economics that keep it running. The study shows that criminal actors can acquire ready‑to‑deploy ransomware kits, phishing toolkits, and botnet rentals from semi‑legitimate online marketplaces that masquerade as legitimate services, using streamlined purchasing processes and often cryptocurrency payments.

The ease of procurement lowers the technical barrier for new threat actors, accelerates the spread of ransomware attacks, phishing campaigns, and DDoS operations, and fuels a rapid expansion of the overall threat landscape. Defenders must understand this supply chain to anticipate emerging tools, detect abuse patterns early, and target the financial and infrastructural nodes that sustain the CaaS market.
