As discussed before, it is always better to triple check when you are going to send any crypto if there's any changes to the address or not. If I say something then I would say that it is better to be safe than sorry. Well, it doesn't feel good when you lost something that you have work hard to get it or earn it and just vanish just like that. It's good that you share this to remind others who have already know this and to let others know about it that doesn't know about this yet. My opinion about how you get this is I think you may have downloaded a software that isn't downloaded from the original website and may be infected with that malware.
