Crimeware-as-a-service (CaaS) is a model where skilled cybercriminals offer tools and services to less experienced offenders, enhancing the ease of committing cybercrimes related to cryptocurrency. This shift has professionalized cybercrime, allowing actors to rent necessary software and execute a wide range of attacks, including extortion and theft. Such activities largely occur on the dark web, which requires specialized access to view these illegal services. CaaS operates in a cycle where developers create services that are marketed to potential buyers in the underground economy. Cybercriminals now sell specific tools for various forms of attacks, including phishing and DDoS attacks, simplifying the process for non-technical users. As a result, even inexperienced criminals can conduct significant attacks, leading to substantial financial losses for victims. The use of specific types of malware has increased, and the collaborative nature of these criminal activities complicates law enforcement's ability to intervene. To protect against these threats, crypto users need to adopt proactive security measures, including using hardware wallets, enabling multifactor authentication, and regularly monitoring account activities.
