Phishing attempt - be careful

I logged in into Poloniex (for the first time this yr) and shortly after I received the above e-mail that seems to originate from Binance.

It asks if I tried to login at Binance from a MacOS system from Hong Kong.
If not, I should call a number.
I did't entry the Binance web site.

The number is a Swiss number.

E mail seems trustworthy at first look, is written in my language with no errors with a Swiss quantity to call (but there's the missing anti-phishing code and the sender was not Binance however sand.com).

Is perhaps coincidence, but the e-mail used at Poloniex never received phishing emails. So I'm wondering if there's somebody at Poloniex is giving present login knowledge to a scammer. Watch out.
