More about the "Attached Payment Invoice" scam email

This phishing email encourages recipients to confirm the delivery date using the attached "payment invoice". The file attached to this email is an Excel document named "Invoice_20210914.xlsx" (its name may vary). Once that document is opened, it prompts users to enter an email address and a password to view the file.

Scammers behind this phishing email aim to gain login information (email addresses and passwords). They can use the obtained information to hijack online accounts (e.g., email, social media, gaming, and other accounts). Typically, fraudsters try to access multiple accounts with the stolen login credentials.

Depending on the type of accessed accounts, scammers can use them to send spam, deliver malware, steal money, make fraudulent purchases, and more. Thus, it is strongly recommended not to provide sensitive information on suspicious pages or reply to emails of this kind.

Similar scam emails in general

The purpose of phishing emails is to lure recipients into providing credit card details, ID card information, login credentials, social security numbers, or other details. Usually, such emails appear legitimate since most scammers pretend to be legitimate companies (or other entities) or real people.

Examples of phishing emails are "Validate Your Wallet Email Scam", "Update Your Email Account Scam", and "Unknown Browser Login Email Scam". They include links to phishing pages or ask to provide information directly via email. Cybercriminals can also use email to deliver malware.

How do spam campaigns infect computers?

When cybercriminals use email to trick users into infecting computers, they send malicious files or links. Their goal is to trick users into downloading and executing malware by themselves. Examples of file types used to distribute malware are malicious MS Office, PDF documents, JavaScript files, archives, executables, and ISO files.

Not all files infect computers immediately after opening them. For instance, users infect computers via malicious MS Office documents after enabling macros commands (editing or content).

How to avoid installation of malware?

Be cautious when opening attachments or links in emails from unknown sources, especially when emails do not concern you. Do not open the contents of emails without being sure it is safe. Download programs and files from reputable sources such as official websites. Be wary of clicking on ads and links on suspicious websites.

Ensure that all software and the operating system is always up-to-date. 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:

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.

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.
