The fees depend on the ransomware's complexity and features, and generally, there's an entry fee to become a member. RaaS creators host their ransomware on dark net sites and allow criminals to purchase it as a subscription - much like a SaaS model. RaaS involves perpetrators renting access to a ransomware strain from the ransomware author, who offers it as a pay-for-use service.However, paying the ransom does not guarantee protection of the data either, as the attackers have access to the stolen data.

Historically, the two main types of ransomware are crypto and locker. To understand the concept, let's look at the four types of ransomware, along with examples of specific ransomware strains and their effect on the security landscape.
