Product Review Request Email Scam: HTML Attachment Trap
Written by: Lapain Epuran
Published on:
A new buyer appears to have found your business. The email is polite, names a procurement manager, and asks whether your company can manufacture a product described in the attachment. For a sales team, that can look like an ordinary opportunity.
The Product Review Request email scam is a phishing campaign. Its attachment is not a product specification document. It is an HTML file that opens a fake email login and sends the submitted credentials to criminals.
Reconstructed example of the Product Review Request phishing email. This illustration is not the original message.
Overview
This campaign disguises itself as a business procurement inquiry. An observed version claims to come from a procurement manager named Gabriel Oliveira at AURORA IMPORT & EXPORT LTDA. and asks the recipient to review specifications for a possible manufacturing order.
The attached filename, “PRODUCT_SPECIFICATIONS.pdf#02055.xls.html,” is designed to look like a mixture of PDF and spreadsheet formats. Its true extension is .html, which allows the file to display a web page in the browser.
The business request creates a believable reason to open a file
Manufacturers, wholesalers, designers, and sales departments regularly receive requests for quotations and technical reviews. The message avoids an obviously extravagant promise and instead asks a normal pre-sales question.
The named person and company provide a story, not authentication. Criminals can borrow real business identities, invent them, or combine public details from several sources.
The attachment is a web page wearing a document name
Windows and some mail clients may shorten a long filename or emphasize the familiar words near its beginning. A recipient can see “PRODUCT_SPECIFICATIONS.pdf” while overlooking the final .html extension.
Opening an HTML attachment launches locally stored web content in a browser. That content can display logos, forms, scripts, and background pages without being a genuine PDF or Excel workbook.
The fake login targets the recipient’s mailbox
The email address and current password
One-time verification codes
Microsoft 365, Google Workspace, or webmail access
Business contacts, quotes, invoices, and contracts
Password-reset messages for connected services
The company named in the message is not responsible for the campaign. The scammer uses a procurement identity to place a credential-harvesting page directly in front of employees who handle new business.
Why a Product Review Request Can Bypass Caution
New customers are expected to be unfamiliar
Most phishing advice tells people to distrust unknown senders, but sales and procurement roles must communicate with strangers. The campaign exploits that necessary openness.
A first contact with no previous thread is not automatically fraudulent. It does, however, require independent verification before an unusual attachment is opened.
The request is flattering without being excessive
The email implies that the recipient’s company may be capable of fulfilling a meaningful order. It invites expertise and suggests potential revenue, which can make the attachment feel worth a quick look.
Unlike a lottery lure, the promise is understated. The attacker relies on business curiosity and routine workflow rather than excitement alone.
Real procurement systems generate long filenames containing product numbers, dates, and multiple descriptors. The phishing file copies that clutter to hide its final extension.
The inclusion of “.pdf” and “.xls” inside the name does not change the file type. Only the final effective extension and the file’s actual content determine how it opens.
How the Product Review Request Email Scam Works
Step 1: The attacker selects business-facing recipients
Addresses for sales, purchasing, management, quotes, and general enquiries are often published on company websites. Individual employee details can also come from professional networks and data breaches.
The attacker does not need deep knowledge of the company. A generic manufacturing request can be sent to many industries and still reach someone willing to review it.
Step 2: A procurement identity is constructed
The email includes a personal name, job title, company name, and location. A professional signature and formal language make the sender look like a legitimate buyer.
These details may be copied from a real firm that has no connection to the message. Calling a number or replying to an address supplied only by the email does not provide independent verification.
Step 3: The recipient is asked to assess specifications
The message asks whether the business can manufacture a product as described. This establishes a practical reason to inspect the attachment before discussing prices or quantities.
Important commercial details are deliberately withheld from the email body. The victim must open the file to learn what the supposed opportunity involves.
Step 4: A disguised HTML file is opened
The filename places familiar extensions before the real .html ending. When opened, the file launches in a browser rather than in a trusted PDF reader or spreadsheet application.
An HTML file can run interface code and send information over the internet. Even when saved on the device, it should not be trusted simply because the browser address begins with a local file path.
Step 5: The file displays a provider-themed sign-in
The page may imitate Gmail, Outlook, Yahoo, or a generic company webmail portal. It can prefill the recipient’s address and display a blurred document or real provider page behind the form.
The fake login claims authentication is necessary to view protected specifications. A legitimate document attachment does not require the recipient to submit an email password to local HTML code.
Step 6: The form transmits the credentials
After submission, scripts inside the file can send the email address and password to an attacker-controlled service. The victim may see an error, blank page, or redirect afterward.
Any “incorrect password” message must be treated as part of the deception. The first entry may already have left the device.
Step 7: Criminals enter the real business mailbox
Stolen credentials are tested against Microsoft 365, Google Workspace, webmail, and single sign-on portals. An attacker may also request a genuine multi-factor prompt.
Once inside, the criminal can study real customers, invoices, vocabulary, and approval chains. That intelligence makes later fraud much more convincing.
Step 8: The compromise becomes business email fraud
The account can be used to send new phishing attachments or alter payment instructions in existing conversations. Messages from a real employee address are harder for partners to dismiss.
Attackers may create hidden forwarding rules and wait for a valuable transaction. The visible product-review email can therefore be only the first step in a longer intrusion.
How to Inspect the Attachment Without Opening It
Show complete file extensions
Configure the operating system to display known extensions. Read the name from the end, not from the first familiar term inside it.
A filename ending in .html or .htm is a web page. A name such as “specifications.pdf.html” remains HTML regardless of the word “pdf.”
Use the mail client’s file information
Check the declared type, size, and any security warning. A tiny HTML attachment is inconsistent with a detailed catalog containing high-resolution product drawings.
Do not use a preview if the security product treats preview and opening the same way. Forward the message to the security team as an attachment so headers and evidence are preserved.
Verify the buyer through independent channels
Find the organization’s official website yourself and call a published switchboard. Ask to be connected to the named employee and confirm the request without using numbers in the message.
If the company cannot verify the person or project, do not continue. If it can, ask for documents through an established business portal or a newly composed message from a verified address.
Use a managed analysis process
Organizations should route suspicious files to trained security staff or a sandbox designed for untrusted content. Employees should not upload confidential business mail to random public scanners.
Warning Signs in the Product Review Email
An unexpected buyer sends specifications before any conversation.
The sender domain does not match the represented company.
The file has several apparent extensions in one name.
The final extension is .html or .htm.
The attachment opens in a browser instead of a document reader.
A local file asks for an email or Microsoft 365 password.
The login branding changes based on the email address.
The sender discourages independent contact or creates a tight deadline.
A well-written inquiry can still be malicious. The strongest warning is the workflow: an unsolicited HTML file asks for credentials that a product specification has no reason to need.
Why HTML Attachments Are Dangerous
They can operate outside an obvious website
Recipients may know to inspect a website domain but feel safer when a file opens from Downloads. The HTML document can still communicate with remote servers and submit form data.
The local path shown in the address bar identifies where the interface file is stored, not where entered credentials will be transmitted.
They can imitate several providers
One phishing kit can examine the recipient’s address and select matching colors and logos. This adaptability lets the same attachment target several email ecosystems.
A generic webmail form can also avoid using a brand entirely. Employees with privately hosted email may find that neutral design plausible.
They can hide the destination from ordinary link checks
The original email may contain no visible phishing URL. Simple filtering that focuses on message links can miss a form embedded inside an attachment.
Organizations should consider controls for high-risk attachment types and educate staff that HTML files are active web content, not passive documents.
What a Stolen Business Mailbox Exposes
Sales and procurement accounts often contain pricing, bank details, tax forms, customer lists, and contract discussions. Even without direct access to a bank, that information can support convincing invoice fraud.
The mailbox may also provide single sign-on access to document storage, customer management tools, chat, and other cloud services. The scope depends on the permissions assigned to the user.
Attackers can study writing style and signature blocks, then reply inside real threads. A partner may trust the conversation history even when the newest bank account belongs to a criminal.
Fast reporting matters. Security teams can revoke sessions, preserve logs, block the attachment, search for other recipients, and warn partners before a fraudulent request is paid.
How Businesses Can Prevent Similar Attacks
Block or quarantine HTML attachments when business needs allow. If they are required, place them behind additional review and do not permit scripts or forms to run by default.
Use phishing-resistant multi-factor authentication for email and single sign-on. Limit administrative privileges and separate payment approval from the mailbox of one employee.
Require independent verification for new suppliers, changed banking details, and urgent payment instructions. Use a known phone number and a second authorized employee.
Train customer-facing teams with examples that match their work. Generic awareness material is less effective when a salesperson regularly receives legitimate attachments from unknown people.
What to Do if You Have Fallen Victim to This Scam
Close the HTML page. Do not enter another password or approve any verification prompt.
Disconnect if unexpected software started. Remove the device from the network and contact IT if the file launched downloads, scripts, or installation requests.
Change the exposed password. Use the official email service from a clean device and create a unique replacement.
Revoke active access. Sign out all sessions and remove unknown tokens, connected apps, app passwords, delegates, and authentication methods.
Inspect mailbox settings. Check forwarding, filters, inbox rules, automatic replies, and sent or deleted mail for attacker changes.
Replace reused credentials. Prioritize cloud, finance, customer-management, and vendor portals tied to the business address.
Notify the security team immediately. Provide the original email, attachment name, time opened, data entered, and any prompt approved.
Search for secondary fraud. Review recent password resets, file access, supplier conversations, and changes to payment instructions.
Warn customers and partners if necessary. Tell them how to verify recent requests without relying on the compromised mailbox.
Contact financial institutions. Attempt a transfer recall and protect affected accounts if banking details or payments were exposed.
Run a trusted security scan. Use Malwarebytes to check for information stealers, malicious extensions, and remote-access software, even if credential theft was the obvious goal.
Report and block the campaign. Submit the message through company and provider channels, and consider AdGuard to block known phishing and redirect domains.

Is PRODUCT_SPECIFICATIONS.pdf#02055.xls.html a PDF?
No. Its final extension is .html, so it is a web page. The words “pdf” and “xls” inside the filename are camouflage.
Can opening an HTML file steal my password automatically?
This campaign displays a form and relies on the victim to submit credentials. HTML can also contain active code, so unexpected files should still be handled as untrusted content.
What if the named company is real?
Real company details can be impersonated. Contact the business through information you find independently and confirm the person and request before opening files.
Why did the page show my email provider?
Phishing code can infer a provider from the address or display a preselected template. Matching branding does not prove the page is connected to that service.
Am I safe if I opened the file but entered nothing?
The credential risk is lower, but report the event and check whether anything downloaded or ran. Follow your organization’s incident process rather than assuming the file was passive.
Should a real product document require my email password?
No. Protected business portals may require their own verified authentication, but a document should never collect your email password through an attached HTML form.
The Bottom Line
The Product Review Request email scam turns a plausible sales opportunity into a credential trap. Its long attachment name hides an HTML file that imitates an email login instead of showing genuine specifications.
Verify new buyers independently and read file extensions from the end. If you submitted credentials, change them immediately, revoke sessions, inspect mailbox rules, and involve your organization’s security team before the compromise develops into payment fraud.
10 Rules to Avoid Online Scams
Here are 10 practical safety rules to help you avoid malware, online shopping scams, crypto scams, and other online fraud. Each tip includes a quick “if you already got hit” action.
Stop and verify before you click, log in, download, or pay.
Most scams win by creating urgency. Verify using a trusted method: type the website address yourself, use the official app, or call a known number (not the one in the message).
If you already clicked: close the page, do not enter passwords, and run a malware scan.
Keep your operating system, browser, and apps updated.
Updates patch security holes used by malware and malicious ads. Turn on automatic updates where possible.
If you saw a scary “update now” pop-up: close it and update only through your device settings or the official app store.
Use layered protection: antivirus plus an ad blocker.
Antivirus helps block malware. An ad blocker reduces scam redirects, phishing pages, and malvertising.
If your browser is acting weird: remove unknown extensions, reset the browser, then run a full scan.
Install apps, software, and extensions only from official sources.
Avoid cracked software, “keygens,” and random downloads. During installs, choose Custom/Advanced and decline bundled offers you do not recognize.
If you already installed something suspicious: uninstall it, restart, and scan again.
Treat links and attachments as untrusted by default.
Phishing often impersonates delivery services, banks, and popular brands. If it is unexpected, do not open attachments or log in through the message.
If you entered credentials: change the password immediately and enable 2FA.
Shop safely: research the store, then pay with protection.
Be cautious with brand-new stores, “closing sale” stories, and prices that make no sense. Prefer credit cards or PayPal for dispute options. Avoid wire transfers, gift cards, and crypto payments.
If you already paid: contact your card issuer or PayPal quickly to dispute the transaction.
Crypto rule: never pay a “fee” to withdraw or recover money.
Common patterns include fake profits, then “tax,” “gas,” or “verification” fees. Another is a “recovery agent” who demands upfront crypto.
If you already sent crypto: stop paying, save evidence (wallet addresses, TXIDs, chats), and report the scam to the platform used.
Secure your accounts with unique passwords and 2FA (start with email).
Use a password manager and unique passwords for every account. Enable 2FA using an authenticator app when possible.
If you suspect an account takeover: change passwords, sign out of all devices, and review recent logins and recovery settings.
Back up important files and keep one backup offline.
Backups protect you from ransomware and device failure. Keep at least one backup on an external drive that is not always connected.
If you suspect infection: do not connect backup drives until the system is clean.
If you think you are a victim: stop losses, document evidence, and escalate fast.
Move quickly. Speed matters for disputes, account recovery, and limiting damage.
Stop payments and contact: do not send more money or respond to the scammer.
Call your bank or card issuer: block transactions, replace the card if needed, and start a dispute or chargeback.
Secure your email first: change the email password, enable 2FA, and remove unfamiliar recovery options.
Secure other accounts: change passwords, enable 2FA, and log out of all sessions.
Scan your device: remove suspicious apps or extensions, then run a full malware scan.
Save evidence: screenshots, emails, order pages, tracking pages, wallet addresses, TXIDs, and chat logs.
Report it: to the payment provider, marketplace, social platform, exchange, or wallet service involved.
These rules are intentionally simple. Most online losses happen when decisions are rushed. Slow down, verify independently, and use payment methods and account controls that give you recourse.
