    It used to be fairly easy to recognize phishing emails but these Yahoo email scams are getting pretty sophiticated.

    I received one the other day (April 2020) that was rather convincing but after some consideration decided it wasn't legit. Why? Because these tech service providers would never admit to having had a breach in their security systems. That is the type of data they bury.

    But it isn't just Yahoo.

    I use paper for most of my communications. The trees need to be thinned out anyway, before they kill one another off via overcrowding. Ironic, no?

    I seem to be getting similar messages that appear to be legit, at least the link goes to a working site on the Yahoo domain that shows actual sign in activity.

    However the sending mail address is not from Yahoo.com but yahoo-inc.com which is indeed suspicious.

    Yahoo <no-reply@cc.yahoo-inc.com>

      I've had exactly the same email. My instinct is Phishing. I'll avoid following the email link and go direct to my account where i'll be changing my password for posterity. Better safe than sorry.
