自分のメールアドレスから不審な英文メールが届いた件

メモ

メールチェックしていると、自分のメールアドレスから(差出人が自分)、末尾に載せた内容の英語のメールが届いていました。件名は「Important Updates」です。

内容を要約すると、「あなたのコンピューターをハッキングしてプライバシーにかかわる履歴を入手したので、知り合いに公開されたくなかったら2日以内に1650ビットコインを払え」というものです。読み手に信じ込ませようと、意外と紳士的に書かれています。

もちろん内容はウソで、セクストーション(性的脅迫)詐欺メールと呼ばれるものです。削除すれば何も起きません。

なお、メールアドレスやパスワードが漏洩しているのではと心配な方は、以下のサイトでチェックすることをお勧めします。

I am sorry to inform you that your device was compromised.

I’ll explain what led to all of this. I have used a Zero Day vulnerability with a special code to infect your device through a website.
This is a complicated software that requires precise skills that I have. It works as a chain with specially crafted and unique code and that’s why this type of an attack can go undetected.
You only need one not patched vulnerability to be infected, and unfortunately for you – it works that simple.

You were not targeted specifically, but just became one of the quite a few unlucky people who got hacked that day.
All of this happened a few month ago. So I’ve had time to collect information on you.

I think you already know what is going to happen next.
During that time, my software was quietly collecting information about your habits, websites that you visit, searches you do, texts you send.
There is more to it, but I have listed a few reasons for you to understand how serious this is.

For you to clearly understand, my software controlled your camera and microphone as well and it was impossible for you to know about it.
It was just about right timing for me to get you privacy violated.

I’ve been waiting enough and have decided that it’s time to put an end to this.
So here is my offer. I need a consulting fee to delete the media content I have been collecting.
Your privacy stays untouched, if I get paid.
Otherwise, I will leak the most damaging content to your contacts and post it to a public tube for perverts to explore.

I understand how damaging this will be for you, and amount is not that big for you to keep your privacy.
Please dont blame me – we all have different ways of making a living.

I have no intention of destroying your reputation or life, but only if I get paid.
I don’t care about you personally, that’s why you can be sure that all files I have and software on your device will be deleted immediately after I receive the transfer.
I only care about getting paid.

My modest consulting fee is 1650 US Dollars transferred in Bitcoin. Exchange rate at the time of the transfer.
You need to send that amount to this wallet: j29n77uiaAfu7093uAFdsaiohg8aweFG(※適当な文字列に変換しました)

The fee is non negotiable, to be transferred within 2 business days.
We use Bitcoin to protect my identity.

Obviously do not try to ask for any help from anybody unless you want your privacy to be violated.
I will monitor your every move until I get paid. If you keep your end of the agreement, you wont hear from me ever again.

Take care.

追記:続けて次のメールも来ました。

Waiting for the payment.

Hello!
Have you recently noticed that I have e-mailed you from your account?
Yes, this simply means that I have total access to your device.

For the last couple of months, I have been watching you.
Still wondering how is that possible? Well, you have been infected with malware originating from an adult website that you visited. You may not be familiar with this, but I will try explaining it to you.

With help of the Trojan Virus, I have complete access to a PC or any other device.
This simply means I can see you at any time I wish to on your screen by simply turning on your camera and microphone, without you even noticing it. In addition, I have also got access to your contacts list and all your correspondence.

You may be asking yourself, “But my PC has an active antivirus, how is this even possible? Why didn’t I receive any notification?” Well, the answer is simple: my malware uses drivers, where I update the signatures every four hours, making it undetectable, and hence keeping your antivirus silent.

I have a video of you wanking on the left screen, and on the right screen – the video you were watching while masturbating.
Wondering how bad could this get? With just a single click of my mouse, this video can be sent to all your social networks, and e-mail contacts.
I can also share access to all your e-mail correspondence and messengers that you use.

All you have to do to prevent this from happening is – transfer bitcoins worth $1450 (USD) to my Bitcoin address (if you have no idea how to do this, you can open your browser and simply search: “Buy Bitcoin”).

My bitcoin address (BTC Wallet) is: j29n77uiaAfu7093uAFdsaiohg8aweFG(※適当な文字列に変換しました)

After receiving a confirmation of your payment, I will delete the video right away, and that’s it, you will never hear from me again.
You have 2 days (48 hours) to complete this transaction.
Once you open this e-mail, I will receive a notification, and my timer will start ticking.

Any attempt to file a complaint will not result in anything, since this e-mail cannot be traced back, same as my bitcoin id.
I have been working on this for a very long time by now; I do not give any chance for a mistake.

If, by any chance I find out that you have shared this message with anybody else, I will broadcast your video as mentioned above.
