This is the only link [the first one, below] or site that matters when it comes to the Equifax hack. There are many phishing websites disguising themselves, and reports are coming in that hoax or fake emails are popping into Inboxes. Use caution. ONLY go through Equifax, seeming as though they are the ones who caused the mess. As they likely already have your identity, and then lost it via a hack, you may as well follow the steps off the link below to get yourself courtesy identity theft protection for a few years [that is their penance].
I would even emphasize that you should not take my [or anyone’s] word for it, and double check on Equifax’s website yourself.
