Received call from 1-800 stating iCloud account was breached

is this call possibly legit? or most likely a scam?

just received a call from 1-866-7**-5**9, saying my account has had a security event and my icloud account has been breached/locked (not sure which i wasn't paying close enough attention), it advised not to perform an financial transactions etc... on my phone... seemed legit but i don't trust those kinds of calls, so i thought i'd contact support directly and it seems when i searched on apple site, this is where i got to... this seems like a community site (not apple support directly) so i guess if anyone has received tone of these calls and/or if anyone knows a way to verify my account?

thanks for any feedback
