It's my first post here. Today I received a message from my mother, I am from Hong Kong so the message is Chinese. The upper message is from my mother (she reminded me to lock the door since she didn't go back home yesterday), and the message below is from the hacker. And you can see that the fraud message looks like from my mother. He or she just asked me to transfer money to a bank account. When I went back home, I asked my mother, but there is no such conversation record on her phone. And of course, she mentioned that she received no notification during noon.

I wonder how the hacker do that? By the way, the hacker only sent message to me, my sister or my mother's friend didn't receive such message.
