At work or at home, I often find some useful piece of software. Sometimes I may find it on a forum, mentioned on a video, or by talking to a colleague.
But how do I know if the editor of the software I install can be trusted ?
To clarify, I am not asking if I can be sure that there are no security issues within the software provided. I am asking how I may check the reputation of the editor in order to prevent the case where the software I install may just be a free tool they provide as an excuse to get a backdoor into my computer, to install a keylogger or basically anything malicious on purpose.
