I need advice!!! Hacked account

I think I screwed up sooo bad!! My sister’s account got hacked the other day. I just logged onto my account and saw that her account was in Russian. I messaged it saying that EPIC is aware it was hacked. I instantly blocked the account, it was obviously already sold. AM I A TARGET NOW?? I’m freaking out and scared I’ll get hacked. I regret sending them a message. I’m going to change all my passwords and everything to be safe.

EPIC actually emailed my sister and told her not to worry, that no one can make changes on the account until ownership is proven. How can these people get in and unlink her accounts if that is the case?? I’m genuinely confused and very worried. I’m so dumb. I just want to know if you guys think I’ll be targeted now :( and if you’ve been hacked, have you gotten your accounts back?
