自分のメールアドレスがメールの差出人に設定された(赤い所)詐欺メールが届きました。

これは、詐欺(なりすましメール)で、PCがハッキングされ自分から自分宛に送信した様に見せかけたモノです。
BTCアドレスが記載されており、送金する様な内容となっていますが絶対に送信しない様にしましょう。
以下が実際に送られてきたメールの内容です。
Hi!
As you may have noticed, I sent you an email from your account.
This means that I have full access to your account.I’ve been watching you for a few months now.
The fact is that you were infected with malware through an adult site that you visited.If you are not familiar with this, I will explain.
Trojan Virus gives me full access and control over a computer or other device.
This means that I can see everything on your screen, turn on the camera and microphone, but you do not know about it.I also have access to all your contacts and all your correspondence.
Why your antivirus did not detect malware?
Answer: My malware uses the driver, I update its signatures every 4 hours so that your antivirus is silent.I made a video showing how you satisfy yourself in the left half of the screen, and in the right half you see the video that you watched.
With one click of the mouse, I can send this video to all your emails and contacts on social networks.
I can also post access to all your e-mail correspondence and messengers that you use.If you want to prevent this,
transfer the amount of $709 to my bitcoin address (if you do not know how to do this, write to Google: “Buy Bitcoin”).My bitcoin address (BTC Wallet) is: 15pY2U8WBZBJRVxGhh8WRXsdkXQbMKD8k9
After receiving the payment, I will delete the video and you will never hear me again.
I give you 48 hours to pay.
I have a notice reading this letter, and the timer will work when you see this letter.Filing a complaint somewhere does not make sense because this email cannot be tracked like my bitcoin address.
I do not make any mistakes.If I find that you have shared this message with someone else, the video will be immediately distributed.
Best regards!

記載されていたビットコインアドレスのトランザクションを追うと、結構動いています。

こういったモノにいったん屈してしまうと、新たな犯罪の標的にされてしまう可能性もあるので十分注意してください。
これは「差出人の名前」を宛先に変更しただけのモノでそんなに難しい事ではありません。
手紙も宛先が判っていれば、差出人の名前が無くても届きますよね?
それと一緒です。
最近の詐欺は非常に巧妙になっているので共有させていただきました。
