Sextortion spam campaign examples
We have analyzed countless spam letters; "Some Bad News That You Are About To Hear", "I Regret To Inform You About Some Sad News For You", and "I am a Russian hacker who has access to your operating system" are just a few examples of sextortion scam emails.
This mail uses a wide variety of scam models and disguises (e.g., messages from legitimate companies, organizations, institutions, etc.). In addition to various scams, spam emails are also used to proliferate trojans, ransomware, and other malware.
How do spam campaigns infect computers?
Once a virulent file is executed, run, or otherwise opened - the infection process is triggered. For example, Microsoft Office documents infect devices by executing malicious macro commands.
How to avoid installation of malware?
We strongly recommend exercising caution with incoming mail. The attachments and links found in dubious/irrelevant emails and messages - must not be opened as that can result in a system infection. Additionally, it is important to use Microsoft Office versions released after 2010 since they have the "Protected View" mode that prevents automatic macro command execution.
However, malware is proliferated using various methods. Therefore, we also advise downloading from official/verified channels and activating/updating software with legitimate tools (as illegal activation tools ["cracks"] and third-party updaters may contain malicious programs).
Another recommendation is to be vigilant when browsing since fraudulent and malicious content usually appears harmless.
We must stress the importance of having a reputable anti-virus installed and kept up-to-date. This software must be used to run regular system scans and to remove detected threats. If you've already opened malicious attachments, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Types of malicious 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.
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.
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.
Example of a spam email:
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.

How did cyber criminals get my email password?
Cyber criminals could have obtained your email credentials through a data breach. Although it is far more likely that the password was acquired through a phishing scam you've fallen victim to. It could have been a fake email account login webpage, a bogus platform/service registration form, and so on.

I have read a spam email but didn't open the attachment, is my computer infected?
No, merely opening a spam email will not initiate any system infection processes. Malware download/installation is triggered when the attachments or links present in this mail are opened/clicked.
