A request for prices arrives while you’re working through the inbox. There are project drawings to review, and the sender seems ready to place an order.
Before opening the files, take a closer look at the invitation. A few details can change how you should handle the entire request.

Overview
A quotation request creates a reason to open the document
The Project Specifications & Drawings Review email scam approaches the recipient as a potential business contact, rather than threatening to close an account.
A reported version impersonates klarx GmbH and offers a SharePoint link to a PDF. It asks the recipient to review specifications, provide prices, and send an invoice.
That combination fits the rhythm of a purchasing department. To quote accurately, someone needs to read the drawings first. The document becomes an apparently necessary starting point.
The important question is where the Open button leads
The reported destination is a credential-harvesting page, not a genuine project document. A precise Microsoft-style sign-in design has not been independently confirmed here.
Phishing means the sender is trying to obtain information by impersonating a trusted party. In this case, the business opportunity supplies the reason to sign in.
There is no need to prove that every detail in the signature is false. A real address or company registration cannot authenticate a link beside it.
The company and the invitation are separate things
klarx is a real business. Its official legal notice identifies a Munich company and registered address. Those public details can be copied.
The warning concerns the impersonating email, not a finding that the real company operates a phishing service or that its systems were breached.
- The commercial request is unexpected or cannot be matched to an existing conversation.
- The document is represented by a link, so its filename does not establish what will open.
- An unfamiliar page requests account access before showing the promised material.
- A copied signature gives the message credibility without proving who sent it.
Why This Message Can Feel Like Real Work
A purchasing email doesn’t have to look dramatic to be persuasive. It only needs to resemble something the recipient already handles several times a day.
Think of an estimator waiting on drawings, a supplier preparing a quote, or an accounts employee checking an invoice request. Opening documents is part of the job.
The lure borrows that ordinary workflow. Instead of asking for a password directly, it presents a task that appears to require access to a shared file.
The employee may be thinking about the potential order, the deadline, or whether the attachment contains enough specifications. The destination of the link becomes a secondary concern.
A document-sharing logo can make the next screen seem unsurprising. Many legitimate files require authentication, so the appearance of a login box is not automatically suspicious.
What matters is the relationship between the request, the sender, and the service receiving the credentials. A familiar logo cannot supply a missing business relationship.
This is also why spelling tests aren’t enough. A polished request can still be fraudulent, while a genuine customer may write imperfect English.
How the Project Drawings Email Scam Works
Step 1: A plausible business task gets your attention
The message opens a conversation about work you could reasonably perform. The reader is invited to assess a project rather than consider an obviously unrelated offer.
A job title, telephone number, website, and formal company footer can make the sender look accountable. None requires the sender to control the company being named.
For a small business, a possible new customer can be especially compelling. Taking a minute to review a file feels like good service, not an unusual risk.
Pause at that first decision. Was there an earlier call, quotation request, or introduction? If the message refers to a discussion you never had, verify it separately.
Don’t let a copied reply chain settle the question. The words beneath a message can be edited just as easily as the signature at the bottom.
Step 2: The file listing turns a link into an apparent attachment
A row showing a filename and an Open button feels more concrete than a bare web address. It suggests that the document already exists and is waiting.
But a filename printed inside an email is only text. The button can lead somewhere unrelated, regardless of whether the row ends with .pdf.
Hovering over a link can reveal a mismatch without opening it. On a managed work device, use your organization’s reporting tool instead of experimenting with suspicious destinations.
Link protection services sometimes rewrite legitimate addresses. An unfamiliar wrapper is a reason for your IT team to inspect the destination, not proof by itself.
Do not paste private document links into random public scanners. Some links contain access tokens or information that should stay inside your company’s security process.
Step 3: Access to the promised document becomes a login request
The critical transition occurs when the reader stops evaluating project information and starts supplying account information. The document request has redirected the task toward identity.
A counterfeit form can collect credentials while appearing to unlock a file. A padlock only means the connection is encrypted, not that the organization is genuine.
A password manager refusing to fill a familiar account can be a useful warning. Don’t override that hesitation simply because the page carries a Microsoft logo.
Some legitimate organizations use different authentication providers. That complexity makes independent confirmation more important, not a reason to type credentials into every professionally styled page.
If a file cannot be obtained without an unexplained login, ask the known contact to resend it through an agreed channel. A genuine quotation can wait for verification.
Step 4: An exposed work account creates business consequences
Once a password has been submitted to an impostor, treat it as exposed even if the form reports an error. Failure messages can conceal successful collection.
Possible consequences include unauthorized mailbox access, stolen files, or messages sent to customers. These are risks of account compromise, not confirmed outcomes for every recipient.
A mailbox can also reveal ongoing supplier relationships. That context could help an intruder make a later payment-change request look like part of an existing project.
Multifactor authentication helps, but an unexpected approval request is not something to accept merely to finish viewing a document. Report it to the person managing the account.
The right response is to contain the exposed identity. Deleting the original email or running a device scan cannot, on its own, revoke unauthorized cloud access.
Sender, Signature, and SharePoint Checks
Compare the actual sender with the contact you already know
Expand the sender details rather than relying on the display name. Compare the full address and Reply-To field with earlier, independently verified correspondence.
A mismatch needs investigation, but a match isn’t a complete guarantee. A real mailbox can be compromised, and a familiar account can send an unsafe message.
Use a saved telephone contact, established procurement portal, or independently located company channel to confirm the specific request. Don’t use the suspicious email as its own reference.
Ask a concrete question: did your team send this project, to this recipient, through this service? A vague confirmation that the company exists answers something else.
Look for an actual project, not just convincing paperwork
A genuine request should have a business context. The recipient should understand what is being priced, who commissioned it, and how the proposed work relates to their services.
Confidential projects may limit what can be shared publicly. That still doesn’t justify entering your existing email password into an unexplained external form.
Do not send your own invoice, banking details, or tax documents merely to keep the conversation moving. First establish that the customer and request are genuine.
Real SharePoint sharing does not excuse an unsafe destination
SharePoint is a legitimate collaboration platform. Its name in an email does not establish that Microsoft hosts the next page or that a real file is present.
Microsoft’s phishing guidance recommends reporting suspicious messages and involving IT when a work or school account may be affected.
Where available, use your normal Microsoft 365 workspace to look for expected shared material. Don’t search for an unverified sender’s login portal through sponsored results.
What to Do If You Responded
If you only received the request, report it through your workplace process. Preserve the original message if IT needs it, then follow their instructions for removal.
Receiving this email is not evidence that the computer is infected or that anyone has accessed your work account. Avoid unnecessary password changes across unrelated services.
If you opened the page, stop before supplying anything else. Close it and write down whether you entered information, approved a prompt, downloaded something, or installed software.
Keep the browser address from history if it is available safely. Don’t revisit the destination to recreate the experience for a screenshot.
If you entered a work password, contact IT immediately. Tell them which identity was exposed and when. Change the password through your established corporate access route.
Ask the administrator to investigate sessions, authentication methods, application consent, and mailbox rules. A password reset alone may not address every form of unauthorized access.
Protect any other account using that same password. Give each affected service a unique replacement. Start with email or identity accounts that control password recovery elsewhere.
Do not include the old password in an incident ticket. Describe the exposure without distributing the secret again.
Review the business activity the account could reach. Check with IT before contacting everyone. They can identify affected messages, files, or recipients and coordinate a precise warning.
If invoices or payment instructions changed, have finance verify them with customers through known contacts. Stop a pending transfer before debating who wrote the email.
Handle downloaded software as a separate device incident. On a company machine, let IT decide how to isolate it and preserve evidence before cleanup.
For a personal Windows computer where suspicious software ran, Malwarebytes can help check for malware. A clean scan does not restore a stolen account session.
AdGuard may reduce exposure to malicious advertising during future browsing. It does not authenticate shared files, reverse payments, or replace workplace email security.
Keep a short incident record. Note the subject, sender, destination, exposure time, and actions already taken. Store sensitive evidence securely rather than in a public discussion.
Prompt reporting is useful even when you’re uncertain. It gives the security team a chance to contain the problem before another employee receives the same invitation.

A Safer Routine for Incoming Quotation Requests
Businesses can’t stop opening customer documents altogether. A better routine gives employees a predictable way to confirm unfamiliar work without sacrificing every potential sale.
Route unsolicited project requests to a designated address. Require enough context to identify the buyer before opening externally hosted specifications on a purchasing employee’s main account.
Keep a contact record for established customers and suppliers. When a message suddenly changes the sharing service, use that record instead of the new signature.
Agree on who can approve an unusual login or file format. Employees should not have to make a security exception alone because an apparent customer is impatient.
Finance and sales should also share a way to verify changes in payment instructions. A genuine-looking project thread is not authority to replace bank details.
For a small team without dedicated IT, an established support provider can help set up reporting and account recovery. Find that provider independently, before an alarming email arrives.
Keep verification simple enough that people actually use it. A short call through an existing contact record is more practical than expecting every employee to analyze email headers.
Document who confirmed the request and which sharing channel was agreed. That record gives another employee a trustworthy reference if the conversation later changes direction.
If the supposed customer refuses an ordinary confirmation, don’t let the possible value of the order override the missing identity check. Your quotation process needs a real counterpart.
Frequently Asked Questions
Is klarx responsible for this email scam?
The reported email misuses the identity of a real company. Copied contact details do not establish company involvement, a compromised mailbox, or authorization for the message.
Does a PDF filename mean the link is safe?
No. Text naming a PDF can point to a login form or another page. Assess the destination and the business request, not just the displayed filename.
Why would a quote request ask me to sign in?
Legitimate sharing can require authentication. The problem is an unexpected request that sends your credentials to an impostor instead of an authorized account provider.
What if I submitted the password but saw an error?
Act as though the password was captured. An error doesn’t show whether the form recorded it. Notify your administrator and secure the account through a known route.
Should I warn the person named in the signature?
Use independently verified company contact details if a report is appropriate. Don’t reply to the questionable message or publish accusations against the named employee.
Will scanning the computer fix the mailbox?
No. A scan addresses device threats. Mailbox recovery requires checking account access, sessions, settings, and unauthorized activity, ideally with the administrator responsible for that environment.
The Bottom Line
Do not sign in through the unverified project-drawings invitation. Confirm the customer and obtain the documents through an agreed route before preparing a quotation.
If you already supplied credentials, contact IT now. Securing the exposed work identity matters more than making the suspicious email disappear from your inbox.
