I keep receiving emails that show they are from my brother, with a link to a Russian site. Hovering the mouse over the sender's name display's a Russian origin. Don't click on any links period.
Re: “I keep receiving emails that show they are from my brother...”
The only way they could do that is to steal your brother’s password and use his mailing list.
Or, if your brother already changed his password after the hack, they have created an email account that reads almost exactly like your brother’s real email address to trick you.
[[I keep receiving emails that show they are from my brother,]]
that’s what happened to us- see my previous post on this- only the link is registered to a Ukrainian site -
