Malware and cryptography 23: encrypt/decrypt file via TEA. Simple C/C++ example

﷽

Hello, cybersecurity enthusiasts and white hackers!

In one of the previous posts (and at conferences in the last couple of months) I talked about the TEA encryption algorithm and how it affected the VirusTotal detection score.

With today’s post I want to start a series of my new research, I will be developing different versions of the ransomware malware with different algorithms from cryptography.

I will do this step by step, so perhaps I will post some things, tricks …
