What sort of email scam is "Purchase Order And Proforma Invoice Confirmation"

What kind of email is "Purchase Order And Proforma Invoice Confirmation"?

We have examined this email and determined it is a phishing scam. The message is disguised as a routine business notification about a purchase order and its corresponding proforma invoice, and it urges the recipient to click a link to view the documents. That link leads to a fake login page designed to steal email account credentials. This email should be ignored entirely.

"Purchase Order And Proforma Invoice Confirmation" email scam in detail

The email presents itself as a message from a "Sales Operations Team," informing the recipient that a purchase order and its accompanying proforma invoice are ready for review. It asks them to confirm the order and indicate an expected delivery date. The tone is deliberately professional - designed to blend seamlessly into normal workplace correspondence.

Clicking the "View Invoice & PO" button directs the victim to a phishing page hosted on Google's Firebase Storage platform. Scammers frequently abuse legitimate cloud storage services this way, as links to well-known infrastructure like Google's are far less likely to be blocked by corporate email security filters.

The phishing page is designed to identify the recipient's email service provider and mimic its login interface. Based on the screenshots, it presents itself as a "Gmail Webmail" form, displaying Google's logo alongside fields for an email address and password, and a "Proceed" button to encourage the victim to submit their credentials.

Any login details entered on this page go directly to the scammers. With stolen email credentials, cybercriminals can read private messages, reset passwords on linked accounts, impersonate the victim to their contacts, and use the compromised inbox to spread further phishing campaigns.

It is worth noting that Google and Gmail are not connected to this scam in any way. Cybercriminals are abusing Firebase's file-hosting capabilities to serve the phishing page - the platform itself is being misused, not complicit.

Similar scam emails in general

In conclusion, this email is a phishing scam disguised as a routine business inquiry. Its goal is to steal email login credentials through a fake login page hosted on legitimate cloud infrastructure. Recipients should delete the message without clicking any links it contains. In some cases, scams like this are also used to deliver malware.

More examples of similar phishing email campaigns are Payroll Statement, Delivery Status Summary, and You Have Missed A Delivery From DHL.

How do spam campaigns infect computers?

Cybercriminals distribute malware by embedding malicious files in emails as attachments or by including links that lead to harmful downloads. These files can appear in many formats: executable programs, Microsoft Office documents, PDF files, archive files, and scripts. In most cases, the infection only begins once the recipient opens the attached file or follows the linked page.

Office documents are particularly common as malware carriers because they can contain malicious macro commands that trigger an infection when enabled by the user. Executables, on the other hand, often require no further interaction - opening the file can be enough to start the infection chain.

How to avoid installation of malware?

Handle all unexpected emails with caution, especially those asking you to open attachments or follow links. If a message claims to be from a known business but arrives without prior context or carries a sense of urgency, verify with the sender through official channels before taking any action.

Only download software from official developer websites or trusted app stores. Avoid third-party download platforms, file-sharing networks, and tools marketed as cracks or key generators - these regularly bundle malware with otherwise ordinary-looking programs.

Keep your operating system and all installed applications updated, and use a reputable anti-malware tool with real-time protection enabled. If you have already opened a suspicious attachment, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate any infiltrated malware.

Types of malicious emails:

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.

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 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. 

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?

These messages are sent in bulk to large numbers of recipients at once. Cybercriminals obtain email addresses through data breaches, fake sign-up pages, and similar sources. The emails are not personally targeted - most recipients have no prior connection to the sender.

I have provided my personal information when tricked by this email, what should I do?

Change the password for the compromised email account immediately, and enable two-factor authentication if you have not already done so. If the same password was used on other accounts, update those as well. Reach out to the email provider's official support team for further assistance if needed.

I have downloaded and opened a malicious file attached to an email, is my computer infected?

It depends on the file type. Executable files (such as .exe files) typically launch malware the moment they are opened. Document formats like Word or PDF files generally require additional user interaction - such as enabling macros - before malware activates.

I have read the email but did not open the attachment, is my computer infected?

No. Reading an email does not put your computer at risk. An infection typically only occurs when the user clicks a link, opens an attachment, or performs some other action that allows malicious content to execute.

Will Combo Cleaner remove malware infections that were present in email attachment?

Yes, Combo Cleaner can detect and remove most known malware. A complete system scan is recommended, as some sophisticated threats can embed themselves deep within the system and may only be fully identified through a thorough inspection.
