What kind of email is "Large File Send"?
"Large File Send" is an email that our research revealed to be spam. This fake letter operates as a phishing scam targeting email account log-in credentials. It does so by claiming that a file sent to the recipient can only be accessed by following the provided link.
"Large File Send" email scam overview
The spam email with the subject "Pay International Suppliers" (may vary) states that a large file has been sent to the recipient. Supposedly, the nonexistent finance-related file (i.e., "Process the Exchange Rates and Pricing Confirmation") can only be accessed by the direct recipient.
As mentioned in the introduction, this email is fake, as is the information it provides. When we pressed the "Open" button presented in this letter, it resulted in a redirect to a website stating that the visitor had been sent three PDF documents. Both the "View PDF" and "Download PDF" buttons redirected to a phishing site.
This page informed that to view the shared files - the user must log in with the recipient email. However, by entering their email account log-in credentials to this site - users will not access any files but disclose this sensitive data to scammers instead. With this information in their possession, cyber criminals can steal the compromised email accounts.
Furthermore, the content registered through a hijacked email can be stolen as well. To expand on how the unauthorized access can be abused - criminals can use finance-related accounts (e.g., online banking, money transferring, e-commerce, etc.) to make fraudulent transactions or online purchases.
Scammers can also pretend to be the owners of hijacked social accounts (e.g., emails, social media, social networking, etc.) and ask the contacts for loans/donations or distribute malware by sharing malicious files/links.
To summarize, by trusting an email like "Large File Send" - users can experience system infections, serious privacy issues, financial losses, and even identity theft.
If you have entered your log-in credentials to a phishing site, we strongly recommend changing the passwords of all potentially compromised accounts and informing their official support without delay.

Phishing spam campaign examples
"Suspension Notice", "Mail Server Update", "Annual Email Version Upgrade", "E-Mail Storage Bandwidth Limit", and "BRITISH CAMELOT ONLINE LOTTERY" are merely some examples of phishing spam campaigns that we have analyzed recently.
Aside from various scams, deceptive emails are used to infect recipients' devices with trojans, ransomware, and other malware. These letters are usually disguised as "urgent", "important", or even as messages from genuine entities (e.g., service providers, companies, corporations, organizations, etc.).
Spam mail is widespread - therefore, we highly recommend exercising caution with incoming emails, PMs/DMs, and other messages.
How do spam campaigns infect computers?
Once a virulent file is executed, run, or otherwise opened - the malware download/installation process is jumpstarted. For example, Microsoft Office documents infect systems by executing malicious macro commands.
How to avoid installation of malware?
We strongly recommend being vigilant with incoming emails and messages. The attachments/links found in suspicious mail must not be opened, as that may lead to a system infection. It is crucial to use Microsoft Office versions released after 2010 since they have the "Protected View" mode that prevents automatic macro command execution.
In addition to spam mail, malware is also spread via dubious download sources (e.g., freeware and third-party sites, Peer-to-Peer sharing networks, etc.), illegal program activation tools ("cracks"), fake updates, online scams, and malvertising.
Therefore, we advise downloading from official/verified channels and activating/updating programs using legitimate functions/tools. Additionally, it is paramount to be cautious when browsing since fraudulent and malicious online content usually appears ordinary and harmless.
We must emphasize that having a reputable anti-virus installed and kept updated is essential to device and user safety. Security programs must be used to perform regular system scans and remove 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.
Frequently Asked Questions (FAQ)
Why did I receive this email?
Spam emails are not personal. Therefore, thousands of users receive identical letters.
I have provided my personal information when tricked by this spam email, what should I do?
If you have disclosed account credentials - change the passwords of all potentially compromised accounts and inform their official support without delay. And if you have provided other vulnerable private data (e.g., ID card details, credit card numbers, etc.) - immediately contact the corresponding authorities.
I have read a spam email but didn't open the attachment, is my computer infected?
No, merely opening/reading an email will not trigger any system infection processes. Devices are compromised when malicious attachments or files found in spam mail are opened/clicked.
I have downloaded and opened a file attached to a spam email, is my computer infected?
Whether your device was infected might depend on the opened file's format. If it was an executable (.exe, .run, etc.) - most likely, yes - the system was infected. However, document formats (.pdf, .xls, .doc, etc.) may need additional interactions (e.g., enabling macro commands) to begin downloading/installing malware.
Will Combo Cleaner remove malware infections present in email attachments?
Yes, Combo Cleaner can detect and eliminate nearly all known malware infections. It must be emphasized that since high-end malicious software typically hides deep within systems - running a complete system scan is paramount.
