A purchasing email asks for a quote and includes a drawing package. For a supplier, that can look like the start of an ordinary business opportunity.
The trouble begins when the promised drawings are used to steer the conversation toward a login page that has nothing to do with the buyer.
Overview
A familiar sales opportunity
The email is built around a request for quote, a normal part of manufacturing, construction, and supply work. It may name a purchasing manager and an apparently real company.
The reviewed version used a PDF-style drawing filename and a businesslike deadline. That is enough to make a busy recipient worry about losing a legitimate order.
A genuine buyer can be verified through a separate company channel before any attachment or portal is opened.
A drawing file becomes a credential request
Instead of showing plans, the link can open a page that asks for a company email and password. That change is the central warning sign.
A quote package normally needs a file viewer or a procurement portal already known to the supplier. It should not need the recipient’s email password.
The offline page reviewed in this campaign was set up to harvest details, not to help a vendor price a job.
Business data has value beyond one quote
A mailbox login can reveal customer lists, invoices, bank-change conversations, and prior bids. It can also be used to impersonate the company in later exchanges.
Even a phone number and company profile can help an attacker write a much more credible follow-up.
The request is therefore not just a nuisance. It can be the opening move in business email compromise.
A request-for-quote story aimed at sales or purchasing staff
A named purchasing contact used to create familiarity
A PDF-style drawing label that does not deliver drawings
A company email and password request behind the link
A possible launch point for invoice or bank-detail fraud
A problem that can be tested by calling a verified company number
The RFQ drawing lure works because good vendors are trained to respond quickly. A delayed response can mean a missed job.
That normal commercial instinct should not require a password. Pricing a part and proving mailbox ownership are unrelated activities.
Separating those two ideas makes the fake portal much easier to recognize.
How The Scam Works
Step 1: A buyer inquiry arrives at a busy inbox
At this point, a supplier receives an RFQ during a normal workday.
The counterfeit RFQ depends on the idea that the commercial language resembles ordinary vendor correspondence.
For a rushed recipient, the email competes with real requests that need quick answers.
Sales teams are accustomed to sorting inquiries quickly because slow replies can lose legitimate work.
That ordinary urgency is the pressure point for a fake RFQ.
The message arrives when routine efficiency can become a weakness.
In the RFQ version, a supplier receives an RFQ during a normal workday. A vendor’s wish to respond promptly becomes the attacker’s opening.
The procurement details may seem useful, but a supplier receives an RFQ during a normal workday. Real drawings can be confirmed through the buyer’s known channels.
The business risk grows because a supplier receives an RFQ during a normal workday. That is why a suspicious quote deserves an internal alert.
Step 2: A named purchaser creates borrowed credibility
At this point, a purchasing-manager name and company reference appear in the signature.
The counterfeit RFQ depends on the idea that those details can be copied from public business pages or directories.
For a rushed recipient, a convincing signature does not prove the message came from that business.
Purchasing titles and company names are easy to copy from public websites.
A signature can look detailed while having no connection to the mailbox that sent it.
Independent confirmation protects the real company as well as the recipient.
In the RFQ version, a purchasing-manager name and company reference appear in the signature. A vendor’s wish to respond promptly becomes the attacker’s opening.
The procurement details may seem useful, but a purchasing-manager name and company reference appear in the signature. Real drawings can be confirmed through the buyer’s known channels.
The business risk grows because a purchasing-manager name and company reference appear in the signature. That is why a suspicious quote deserves an internal alert.
Step 3: The drawing filename invites a familiar click
At this point, a Drawings_and_Documents PDF label suggests technical files.
The counterfeit RFQ depends on the idea that the familiar extension discourages recipients from questioning the next click.
For a rushed recipient, the alleged file can actually be a link or a portal detour.
Technical drawings are naturally interesting to a supplier preparing a quote.
The PDF label gives the attacker a plausible reason for a click without revealing any real project.
A familiar filename is not proof of a genuine attachment.
In the RFQ version, a Drawings_and_Documents PDF label suggests technical files. A vendor’s wish to respond promptly becomes the attacker’s opening.
The procurement details may seem useful, but a Drawings_and_Documents PDF label suggests technical files. Real drawings can be confirmed through the buyer’s known channels.
The business risk grows because a Drawings_and_Documents PDF label suggests technical files. That is why a suspicious quote deserves an internal alert.
Step 4: The link swaps plans for a sign-in screen
At this point, the destination asks for corporate mailbox credentials.
The counterfeit RFQ depends on the idea that a quote drawing has no reasonable need for full mailbox access.
For a rushed recipient, this mismatch exposes the page as a data-collection step.
A quote can require product details, not the keys to a corporate inbox.
The moment a drawing portal asks for a mailbox password, its purpose has changed.
That mismatch is more important than the quality of the page design.
In the RFQ version, the destination asks for corporate mailbox credentials. A vendor’s wish to respond promptly becomes the attacker’s opening.
The procurement details may seem useful, but the destination asks for corporate mailbox credentials. Real drawings can be confirmed through the buyer’s known channels.
The business risk grows because the destination asks for corporate mailbox credentials. That is why a suspicious quote deserves an internal alert.
Step 5: Credentials can unlock the wider mailbox
At this point, a working mailbox can contain proposals, contacts, and payment discussions.
The counterfeit RFQ depends on the idea that the attacker may search threads for invoicing language or vendor relationships.
For a rushed recipient, the effect can reach far beyond the original RFQ.
Business mailboxes often connect sales, finance, operations, and customers.
One stolen password can provide a map of relationships that took years to build.
The attacker may value those relationships more than the requested quote.
In the RFQ version, a working mailbox can contain proposals, contacts, and payment discussions. A vendor’s wish to respond promptly becomes the attacker’s opening.
The procurement details may seem useful, but a working mailbox can contain proposals, contacts, and payment discussions. Real drawings can be confirmed through the buyer’s known channels.
The business risk grows because a working mailbox can contain proposals, contacts, and payment discussions. That is why a suspicious quote deserves an internal alert.
Step 6: A compromised mailbox enables a second fraud
At this point, a stolen account can be used to send an altered payment instruction.
The counterfeit RFQ depends on the idea that customers may trust a request when it comes from a familiar address.
For a rushed recipient, the later loss can be much larger than the value of a single quote.
Invoice fraud commonly relies on trust established in an existing conversation.
A mailbox compromise lets an attacker insert themselves into threads already in progress.
Phone verification makes that second-stage deception harder.
In the RFQ version, a stolen account can be used to send an altered payment instruction. A vendor’s wish to respond promptly becomes the attacker’s opening.
The procurement details may seem useful, but a stolen account can be used to send an altered payment instruction. Real drawings can be confirmed through the buyer’s known channels.
The business risk grows because a stolen account can be used to send an altered payment instruction. That is why a suspicious quote deserves an internal alert.
Step 7: Silence keeps the fake buyer believable
At this point, the fake buyer may never reply after credentials are collected.
The counterfeit RFQ depends on the idea that that absence can look like an ordinary lost opportunity.
For a rushed recipient, a quick internal alert can reveal whether the account was accessed elsewhere.
A missing buyer reply can seem normal in competitive sales work.
That silence should not end the internal review if credentials were submitted.
Account logs may reveal access attempts before the next fraud message arrives.
In the RFQ version, the fake buyer may never reply after credentials are collected. A vendor’s wish to respond promptly becomes the attacker’s opening.
The procurement details may seem useful, but the fake buyer may never reply after credentials are collected. Real drawings can be confirmed through the buyer’s known channels.
The business risk grows because the fake buyer may never reply after credentials are collected. That is why a suspicious quote deserves an internal alert.
Company, Address, and Fulfillment Checks
A buyer name needs independent confirmation
A real company may exist even when the email is fraudulent. Impersonation uses that fact to make the approach sound ordinary.
Find the business through a trusted directory, then call a published number and ask for the purchasing contact.
Do not use the number or reply address printed in the suspicious inquiry.
A drawing portal should match the relationship
Established customers often use named procurement systems or shared project spaces. An unknown portal deserves a separate verification call.
A password prompt for a drawing file is not the same as a client-specific document room.
Compare the domain with the buyer’s real corporate domain before signing in.
Support must know the actual project
A legitimate purchaser should be able to discuss part numbers, quantities, and the origin of the request.
A vague agent, automated reply, or pressure to reset an email password is a serious warning sign.
Use a verified switchboard or direct contact already present in your customer records.
Commercial data needs a traceable recipient
Quotes can include pricing, margins, drawings, and customer information. Treat them as sensitive even when no payment is involved.
The reviewed page sought credentials rather than providing traceable procurement access.
If the recipient cannot be verified, send no quote and open no file.
Why This Message Can Cause Real Harm
Procurement scams exploit a workplace habit that is usually positive. Companies want staff to respond to qualified opportunities, so an RFQ does not automatically feel suspicious.
A modest verification delay is cheaper than a mailbox compromise. Calling a published company number can resolve the question in minutes.
Never use an email password as a universal key for a document portal. A legitimate system can offer a separate account or a password-reset path you initiated.
Check whether the sender’s domain differs by a letter, hyphen, or unusual suffix. Lookalike domains often depend on a rushed glance.
Shared mailboxes deserve an escalation procedure. If one employee entered credentials, others need to know that account threads may be exposed.
Payment changes should be verified by phone using a known number, even after this particular RFQ has been dismissed. Compromise often creates delayed follow-up fraud.
A seller’s best defense is a simple rule: drawings may require access, but access should never require surrendering a corporate mailbox password.
What to Do if You Have Fallen Victim to This Scam
Stop using the drawing portal and save the original inquiry, including headers, link address, and the filename shown to the recipient.
Notify your IT or security contact immediately if a company email password was typed into the page. Fast reporting matters more than avoiding embarrassment.
Change the affected password from a clean device and revoke active sessions if the email provider offers that option.
Review mailbox forwarding rules, delegates, connected apps, and recent sent messages. Those settings can reveal whether someone tried to retain access.
Warn finance and sales teams about possible invoice or banking-change impersonation. Ask them to verify payment changes by known telephone numbers.
Run Malwarebytes on any computer that downloaded a file or opened an unexpected attachment from the RFQ message.
Use AdGuard to reduce exposure to malicious advertising and known phishing pages while browser access, saved passwords, and extensions are reviewed.
Report the impersonation to the real company through a verified channel and forward evidence to the appropriate fraud-reporting service.

An RFQ gives the attacker a credible reason to contact a business and a reason for the recipient to open drawings quickly.
Can a real company name appear in a fraudulent email?
Yes. Criminals often impersonate real businesses because public names and employee details are easy to find.
Should a PDF drawing require my email password?
No. A drawing portal may need a project account, but it should not ask for the password to your main mailbox.
What can happen after a mailbox password is stolen?
The account can expose customers, invoices, quotes, and payment conversations that support later impersonation attempts.
How can I verify the buyer safely?
Use a published website, customer record, or independent directory to find a contact. Do not rely on the email signature.
What if I only entered my company email address?
Watch for targeted follow-up messages. Change passwords only if a password was entered or the same page requested a sign-in.
The Bottom Line
The Drawings and Documents email scam disguises credential theft as an ordinary sales opportunity.
Verify a buyer away from the message before opening a portal. A legitimate quote request does not need the password to your business mailbox.
That single distinction can protect customer relationships, invoices, and future payments.
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.
