The canonical link is https://www.comebackalive.in.ua/, but the others seem to have the same donation info, so they should be legit.
I hope you and your family are well.
I think https://comebackalive.org.ua is a phishing website, which has now appeared on https://en.wikipedia.org/wiki/Come_Back_Alive
It was created a few weeks ago in 2022, unlike
https://www.comebackalive.in.ua/
which was created 7 years ago.
Also, I cannot find
comebackalive.org.ua
being referenced anywhere on their old website
Perhaps you could use your connenctions to tell them somebody is impersonating them for phishing purposes?
