I think it's easy!!

G OOD morning,
I need help I'm not practical to do it.

I will explain you with a simple example:

I create a wordlist with a single word, for example "Hello".
How can I make an attack using only this word (hello) in all possible combinations with upper and / or lower case letters of the same word "Hello" and incrementally adding a combination of special characters, letters and numbers, at the beginning, to the end or both to the word "hello"?

Thanks for your help !

Have a look at comboleetor (a custom perl script available at https://www.jimby.name/techbits/recent/comboleetor_2.0/).  It can do what you want.

Some experience with  Unix/Linux command line, the perl scripting language, and basic file handling would be needed.
