Do not trust the "I Know A Lot More Things About You" Email Scam

Also Known As: I Know A Lot More Things About You spam
Damage level: Medium

What is "I Know A Lot More Things About You"?

There are many examples of spam campaigns on the internet. Cyber criminals/scammers proliferate them to deceive unsuspecting recipients into transferring certain sums of money (cryptocurrency).

They claim that they used the recipient's webcam to record humiliating videos (or webcam photos) and threaten to proliferate this content, unless the recipient pays within a specific period. These emails are bogus and should never be trusted.

I Know A Lot More Things About You email spam campaign

The scammers behind this spam campaign send emails with messages containing words that have certain characters replaced with symbols - these closely resemble the characters that form the actual word. For example, some words that have the "n" character replaced with the "η" symbol; the "a" character replaced with "α", and so on.

This technique is used to avoid spam filters. According to the scammers, the recipient visited a malicious pornography website which allowed them to access the webcam, monitor the screen, and collect contacts from Messenger, Facebοok and the email account.

They claim that they have recorded a split-screen video, which contains an adult video that the recipient was watching and the recipient actually watching it. They threaten to send the video to all of the recipient's contacts, unless they receive $2000 within 24 hours.

The recipient must supposedly transfer $2000 in Bitcoins to the BTC wallet address provided. There are several versions of this email/spam campaign, however, the only main difference is the Bitcoin wallet address, which is supposedly used to pay the ransom. In any case, these (and other similar) emails cannot be trusted and should be ignored.

"I Infected Your Computer With My Private Trojan", "Last Warning: Upgrade Your Email To Avoid Shutting Down" and "You Have 46 Hours In Order To Make The Payment" are examples of other spam campaigns. Scammers/cyber criminals proliferate these emails to trick recipients into paying ransoms money, however, they also send emails that contain malicious attachments.

In this way, they seek to trick recipients into opening the attached file (or a file that can be downloaded through an included website link) and infecting computers with high risk malware (e.g., TrickBot, Emotet, Adwind, LokiBot).

How do spam campaigns infect computers?

Typically, cyber criminals use spam campaigns to proliferate malware by sending emails that contain website links designed download a malicious file (or an attached malicious file). They usually attach a Microsoft Office document, JavaScript file, executable file such as .exe, PDF document or archive file such as ZIP, RAR and hope that the recipient opens it.

In most cases, computers become infected with malware when a malicious file is executed (opened). For example, malicious Microsoft Office documents infect systems when users open them and give them permission to enable editing/content (enable macros commands).

Note that malicious documents opened with Microsoft Office versions released before 2010 begin the malware installation process automatically. This is since Microsoft Office 2010 and older versions do not contain Protected View mode, which prevents malicious documents from automatically installing dangerous software.

How to avoid installation of malware

If an email is received from an unknown/suspicious address, is irrelevant and contains a website link or attachment, do not open the contents. Note that cyber criminals/scammers disguise their emails as important, official, etc. Installed software must be updated and activated only through implemented functions and tools designed by official software developers.

No third party updaters or activation tools can be trusted. Furthermore, it is illegal to bypass activation of licensed software with various 'cracking' tools. Software should be downloaded from trustworthy, official websites.

Third party downloaders/installers, dubious web pages, Peer-to-Peer networks (torrent clients, eMule) and other similar sources are often used to distribute unwanted, potentially malicious software. Keep computers safe by regularly scanning them with reputable anti-spyware or antivirus software, and remove 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.

Types of malicious emails:

Phishing email icon Phishing Emails

Most commonly, cybercriminals use deceptive emails to trick Internet users into giving away their sensitive private information, for example, login information for various online services, email accounts, or online banking information.

Such attacks are called phishing. In a phishing attack, cybercriminals usually send an email message with some popular service logo (for example, Microsoft, DHL, Amazon, Netflix), create urgency (wrong shipping address, expired password, etc.), and place a link which they hope their potential victims will click on.

After clicking the link presented in such email message, victims are redirected to a fake website that looks identical or extremely similar to the original one. Victims are then asked to enter their password, credit card details, or some other information that gets stolen by cybercriminals.

Email-virus icon Emails with Malicious Attachments

Another popular attack vector is email spam with malicious attachments that infect users' computers with malware. Malicious attachments usually carry trojans that are capable of stealing passwords, banking information, and other sensitive information.

In such attacks, cybercriminals' main goal is to trick their potential victims into opening an infected email attachment. To achieve this goal, email messages usually talk about recently received invoices, faxes, or voice messages.

If a potential victim falls for the lure and opens the attachment, their computers get infected, and cybercriminals can collect a lot of sensitive information.

While it's a more complicated method to steal personal information (spam filters and antivirus programs usually detect such attempts), if successful, cybercriminals can get a much wider array of data and can collect information for a long period of time.

Sextortion email icon Sextortion Emails

This is a type of phishing. In this case, users receive an email claiming that a cybercriminal could access the webcam of the potential victim and has a video recording of one's masturbation.

To get rid of the video, victims are asked to pay a ransom (usually using Bitcoin or another cryptocurrency). Nevertheless, all of these claims are false - users who receive such emails should ignore and delete them.

How to spot a malicious email?

While cyber criminals try to make their lure emails look trustworthy, here are some things that you should look for when trying to spot a phishing email:

  • Check the sender's ("from") email address: Hover your mouse over the "from" address and check if it's legitimate. For example, if you received an email from Microsoft, be sure to check if the email address is @microsoft.com and not something suspicious like @m1crosoft.com, @microsfot.com, @account-security-noreply.com, etc.
  • Check for generic greetings: If the greeting in the email is "Dear user", "Dear @youremail.com", "Dear valued customer", this should raise suspiciousness. Most commonly, companies call you by your name. Lack of this information could signal a phishing attempt.
  • Check the links in the email: Hover your mouse over the link presented in the email, if the link that appears seems suspicious, don't click it. For example, if you received an email from Microsoft and the link in the email shows that it will go to firebasestorage.googleapis.com/v0... you shouldn't trust it. It's best not to click any links in the emails but to visit the company website that sent you the email in the first place.
  • Don't blindly trust email attachments: Most commonly, legitimate companies will ask you to log in to their website and to view any documents there; if you received an email with an attachment, it's a good idea to scan it with an antivirus application. Infected email attachments are a common attack vector used by cybercriminals.

To minimise the risk of opening phishing and malicious emails we recommend using Combo Cleaner Antivirus for Windows

What to do if you fell for an email scam?

  • If you clicked on a link in a phishing email and entered your password - be sure to change your password as soon as possible. Usually, cybercriminals collect stolen credentials and then sell them to other groups that use them for malicious purposes. If you change your password in a timely manner, there's a chance that criminals won't have enough time to do any damage.
  • If you entered your credit card information - contact your bank as soon as possible and explain the situation. There's a good chance that you will need to cancel your compromised credit card and get a new one.
  • If you see any signs of identity theft - you should immediately contact the Federal Trade Commission. This institution will collect information about your situation and create a personal recovery plan.
  • If you opened a malicious attachment - your computer is probably infected, you should scan it with a reputable antivirus application. For this purpose, we recommend using Combo Cleaner Antivirus for Windows.
  • Help other Internet users - report phishing emails to Anti-Phishing Working Group, FBI’s Internet Crime Complaint Center, National Fraud Information Center and U.S. Department of Justice.
