What is "I Do Know Your Passwords"?

"I Do Know Your Passwords" is one of many email scams used to obtain money from recipients by deception. In this particular, email scammers claim that they have recorded a compromising video, which they will proliferate unless recipients pay $1000 in Bitcoins. Note, all claims in emails of this kind are false and should not be taken seriously. We strongly recommend that you ignore these emails and delete them from the Inbox immediately.

I Do Know Your Passwords spam campaign

The scammer behind this email claims that the recipient's passwords and browsing activity have been obtained. The computer was apparently infected with malware through an adult website, which the recipient had supposedly visited before receiving the message. Installed malware supposedly allowed this scammer to access the recipient's screen and camera, and collect contact lists from Facebook, Messenger, and email accounts. Furthermore, the scammers claims that a double screen video has been recorded, whereby the recipient can be seen watching an adult video. A threat is made to send this video to all of the contacts collected unless $1000 in Bitcoins is received. To avoid spam filters, scammer proliferate this scam by sending the message in password-protected PDF documents and attaching them to emails. Anti-virus suites and other virus detection engines cannot scan password-detected documents, and thus email scams of this type are not marked as 'spam' and recipients receive them in their Inbox (rather than Spam) folders. Typically, passwords for password-protected documents such as this PDF document are provided in the email messages. In any case, none of these email scams can be trusted and they should be deleted from any folder.

We receive a great deal of feedback from concerned users about this type of email scam. Here is the most popular question we receive (in this case, relating to a scam that claims to have obtained compromising videos or photos of the user):

Q: Hi pcrisk.com team, I received an email stating that my computer was hacked and they have a video of me. Now they are asking for a ransom in Bitcoins. I think this must be true because they listed my real name and password in the email. What should I do?

A: Do not worry about this email. Neither hackers nor cyber criminals have infiltrated/hacked your computer and there is no video of you watching pornography. Simply ignore the message and do not send any Bitcoins. Your email, name, and password was probably stolen from a compromised website such as Yahoo (these website breaches are common). If you are concerned, you can check if your accounts have been compromised by visiting the haveibeenpwned website.

There are many other email scams online. Some examples are "I know you are a pedophile", "ChaosCC hacker group", and "The last time you visited a Porn website". Generally, scammers send the messages to trick people into believing that a humiliating video has been recorded (or photo taken), which will be sent to other people unless they pay the scammer a specific sum (typically, in a cryptocurrency). Unfortunately, cyber criminals also use emails to proliferate malware. They attach a file and hope that recipients opens it - it then installs malicious software such as TrickBot, LokiBot, Emotet, FormBook, or other high-risk malware.

How do spam campaigns infect computers?

Spam campaigns/emails are used to distribute malware through files that are attached to them. Therefore, these files cannot infect computers unless recipients open them. If opened, however, they allow the files to install malicious software. Examples of files that can be used to proliferate malware are Microsoft Office or PDF documents, executable files such as .exe, JavaScript files, archives such as ZIP, RAR, and so on. For example, if the attached file is a Microsoft Office document, when opened, it will demand permission to enable macros commands (to enable editing). Once a malicious document receives this permission, it installs malware.

How to avoid installation of malware

Attachments or web links that are included in irrelevant emails and received from unknown/suspicious addresses should not be opened. Generally, scammers/cyber criminals disguise these files and/or emails as important and official. Files should not be downloaded from unofficial, dubious websites, sources such as Peer-to-Peer networks, third party downloaders, or programs installed through third party installers. The safest way to download is to use official websites and direct links. Installed programs should be activated and updated properly, since third party/unofficial tools can be used to distribute malware and infect computers with high-risk malicious software. Note that it is illegal to activate licensed software using 'cracking' tools. Downloaded MS Office documents should be opened with Office 2010 or later versions, since they include "Protected View" mode, which prevents malicious documents from installing unwanted, rogue software. Protect your system by regularly scanning it with reputable anti-virus or anti-spyware software and eliminating detected threats immediately. If you have already opened malicious attachments, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Text presented in the password-protected PDF document, which is attached to "I Do Know Your Passwords" scam emails:

I do know your passwords (check this email subject for one of the passwords), I do know about your daily life, I do know about your internet activities but you do not know anything about me, and you must be wondering why you are getting this email, right? I installed a malware on the adult (porn) website and guess what, you visited this website to have fun (you know what I mean!). While you were watching the porn, your web browser started functioning as an RDP+keylogger, which gave me access to your display screen and camera. Right after that, my software collected all of your contacts from your Facebook account, Messenger account, and email account, then, I created a double screen video. The first part shows the video you were watching (you have a nice taste lol), and the second part shows the recording of your camera (it is you!).  
You have two options -   
1. First option is to ignore this email. In this case, I will send the recorded video clip of yours to all of your contacts and just imagine the humiliation you will feel from this. Don't forget that this can also affect your relationship as well.   
2. Second option is to pay me $1000. We will call it a donation. In this case, I will right away delete your video and all of your information I have about you (including your contact lists) and you will never hear from me again. You can continue your daily life like this never happened.   
You will make the payment via Bitcoin. If you do not know about Bitcoin, search Google for "how to buy bitcoin". You can also get the Bitcoin from sites like Bitstamp, Coinbase, Kraken, Localbitcoins, etc.  
Bitcoin (i.e. BTC) address to which you need to send is -

It is Case-Sensitive, so make sure to copy and paste it, or, you can also scan this QR image to get the BTC address:  
If you are thinking to go to the police, good luck, I have taken every step to make sure that this email cannot be traced back to me. You have 48 hours to pay me. I have a special Facebook pixel in this email, and at this moment, I know that you have read this email. If you want proof, reply to this email, and I will send your video to 4 of your contacts.

After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
