Phishing calls
I received repeated calls from (408) area code #'s which when I answered said it was Apple Support calling about an issue identified with my icloud account. I pressed "1" and it took me to a support person. I ended up speaking with 2 individuals. I connected with them on my Imac through gotoassistant. They looked at my system.log and they sent me an email to my email account with the case id# and a link. They said they were going to have their team investigate further and call me back in the morning. Based on researching this online I'm worried this was a phishing scam.
I didn't reveal passwords or logins but am worried if they could have accessed something confidential if this was not legitimate.
