Is this malware?

I started it up, but it asked for my cc info

Lol no. If it asked for your cc info, then you downloaded it from somewhere other than Github. Try downloading from here: https://github.com/dimaguy/ImpostorHQ/releases
(Also if this is a joke, you made me laugh)

Hi, no we do not collect any data.
You might be under attack from a network of terrorists attacking you for the sole purpose of getting your cc info.
