CradleCore ransomware is a malware offered in the underground as a source code, instead of the classic ransomware-as-a-service (RaaS) model. The malware goes for 0.35 Bitcoin (around $400) but the price is negotiable. The author of the malware is a freelance C++ developer without a significant experience in malware coding.

It is being sold as source code which could lead to the development of new variants derived from the malware.”]
