Beware of fraud in network security

This is a real case that happened in Beichen Hydraulic.

On the morning of October 22th, 2020. An Argentine customer contacted me on the Whats app, saying that the bank account had changed this time (he have bought parts several times before), our company didn't pay,hesent the proforma invoice and screenshots of emails related to it. After checking carefully, I found that our bank account has been tampered, and the sender's email address is very close to mine. (please find attached) Due to the caution of our Argentine customers, we have not been deceived.

Customers are requested to contact the other party in time when they find that their bank account has changed. There must be two or more different contact methods. In addition to the email, please add the other party's Whats app and WeChat.

P.S: If my Argentine customer and I only have email contact, I'm afraid we have been cheated, so Whats app saved us.Again, two or more different contact methods is very important.
