#2106 CryptoBlock ransomware and its C2
CryptoBlock is an interesting ransomware to keep an eye on. We expect this to be a ransomware that is in development to eventually develop into a RaaS (Ransomware as a Service).

Since the ransomware seems to be in development, we decided there might be some weak points and investigate if we could find one. Even though it is in development to be a RaaS, as it seems users have already been infected by this variant somehow.

After getting the name CryptoBlock, we decided to check at VirusTotal and see how many droppers for it we could find there, as well as to get some information on the ransomware. Finding a single dropper on VirusTotal, we noticed it was contacting the domain fliecrypter.in to send a key to and also to get a BTC wallet.
