今日詐欺メールが来た
詐欺だから絶対に振り込まないように
気をつけろ

Hello!

I have very bad news for you.
02/09/2019 - on this day I hacked your OS and got full access to your account hantaku-teiji-kobe@yahoo.co.jp.
Your password is indicated in subject of this email.

So, you can change the password, yes.. But my malware intercepts it every time.

How I made it:
In the software of the router, through which you went online, was a vulnerability.
I just hacked this router and placed my malicious code on it.
When you went online, my trojan was installed on the OS of your device.
