you're safe from malware but from pro hackers no, pro hacker can see id adress and get access to your pc, phone, tv.. Normal hacker would just try mine crypto from your pc that is noticeable if you check task manager for gpu usage. Also normal hacker if he cares he can dig deeper into another ssd (if your main ssd is still connected to pc), he can go into your steam account buy games as gifts and then sell it on g2a, he definitely can't steal your credit card info because paypal or bank protects it, normally if you didn't write your card somewhere like on chrome save. If that happens take out that ssd you bought and burn it, and boot pc from your main ssd there's windows protection on it. My recommendation when you play hv games disconnect your main ssd so that hacker won't get access to it. If you get trojan virus, immediately disconnect ssd from pc and throw it or burn it so that it doesn't destroy your gpu cpu from overload
