New to malware analysis, looking for a string type list


as the title suggests, I’m new to malware analysis and as I was looking over strings in a sample, I came across one that I haven’t seen before using + and / (6AAAAABZg+kFjYm2BgAAUegBAAAAw1WL7IPk+etc…).

I am wondering if there is a list of some kind out there that has examples of certain types of string, like SGVsbG8= is base64, 48 65 6c 6c 6f is hexadecimal, and so on. Thanks!
