The target is asked to trust authority, not inspect software.<\/p>\n<p>Belgium&#8217;s cybersecurity service has <a href=\"https:\/\/safeonweb.be\/nl\/actueel\/pas-op-voor-ceo-fraude-microsoft-teams\" target=\"_blank\" rel=\"noopener\">warned about criminals posing as executives through Teams<\/a>. Requests can concern money, confidential documents, or account access.<\/p>\n<p>The warning describes carefully chosen names and company details. Knowing who chairs a meeting doesn&#8217;t make someone a participant in it.<\/p>\n<p>Microsoft Teams is legitimate. The fraud is the person pretending to be your CEO, board member, or another senior decision-maker.<\/p>\n<h3>The pressure is to make one exception<\/h3>\n<p>A normal approval process suddenly becomes an obstacle. You&#8217;re told the matter is urgent, sensitive, or too important to discuss with the usual colleagues.<\/p>\n<p>That request deserves more scrutiny, not less. A genuine executive should be able to confirm an instruction outside an unexpected conversation.<\/p>\n<p>Watch for combinations like these:<\/p>\n<ul>\n<li>A senior person&#8217;s name attached to a new or external account.<\/li>\n<li>An unscheduled meeting followed by financial or confidential instructions.<\/li>\n<li>A request to avoid calling, involving a manager, or using normal approvals.<\/li>\n<li>New payment information supplied only through the chat.<\/li>\n<li>Questions about credentials or files the sender wouldn&#8217;t ordinarily need.<\/li>\n<\/ul>\n<h3>The real app doesn&#8217;t authenticate the person<\/h3>\n<p>Teams supports conversations with people outside an organization. An external contact isn&#8217;t automatically malicious, but neither is it automatically your internal executive.<\/p>\n<p>The image above illustrates the approach using fictional names. It isn&#8217;t a captured conversation with a real CEO.<\/p>\n<p>The safe response is to pause the instruction and verify the person through a contact route you already trust.<\/p>\n<h2>Why This Message Can Feel Like an Ordinary Work Request<\/h2>\n<p>Most employees don&#8217;t spend their day investigating identities. They answer questions, handle interruptions, and try not to hold up colleagues.<\/p>\n<p>A message inside a familiar collaboration app fits that routine. It can feel less suspicious than an email arriving from an unknown website.<\/p>\n<p>The sender also borrows the company&#8217;s hierarchy. Refusing a stranger is easy; questioning someone apparently above you can feel uncomfortable.<\/p>\n<p>That discomfort is useful to the impersonator. The conversation moves faster when the employee feels that asking for confirmation would look unhelpful.<\/p>\n<p>Public information can make the opening convincing. Executive biographies, company announcements, and professional profiles reveal names, roles, and business relationships.<\/p>\n<p>Those details explain how a stranger might sound informed. They don&#8217;t mean your company has necessarily suffered a data breach.<\/p>\n<p>Likewise, an accurate signature or company logo isn&#8217;t a secret credential. Someone can copy visible branding without controlling the organization&#8217;s accounts.<\/p>\n<p>Look at the instruction itself. Would you normally send this file, approve this payment, or change these details without another person&#8217;s involvement?<\/p>\n<p>If the answer is no, the chat hasn&#8217;t supplied a reason to skip that safeguard. It has supplied a reason to use it.<\/p>\n<h2>How the Microsoft Teams CEO Impersonation Scam Works<\/h2>\n<h3>Step 1: The impersonator chooses a believable identity<\/h3>\n<p>The attacker adopts a senior person&#8217;s name and role. The aim is to appear entitled to give instructions before the recipient asks questions.<\/p>\n<p>A finance employee might expect payment discussions. A legal or administrative worker might expect sensitive documents. The request can be shaped around that access.<\/p>\n<p>This isn&#8217;t limited to the CEO&#8217;s exact title. A supposed director, shareholder, or board representative can create similar pressure.<\/p>\n<p>Matching the display name to a real person is only the first check. It doesn&#8217;t establish who controls the account.<\/p>\n<h3>Step 2: An unexpected chat or meeting opens the door<\/h3>\n<p>The target receives a contact request, message, or meeting invitation. Familiar workplace context makes it tempting to accept and sort out the details afterward.<\/p>\n<p>Before accepting, inspect the account information available in Teams. Pay attention to external indicators and the underlying address, not just the headline name.<\/p>\n<p>Microsoft explains how to <a href=\"https:\/\/support.microsoft.com\/en-us\/teams\/chat\/accept-block-or-delete-chat-or-meeting-requests-from-people-outside-your-organization-in-microsoft-t\" target=\"_blank\" rel=\"noopener\">handle requests from outside your organization<\/a>. Available controls can depend on your workplace configuration.<\/p>\n<p>An invitation being delivered successfully means the service delivered it. It doesn&#8217;t mean your employer approved the person who sent it.<\/p>\n<h3>Step 3: Business details make the request feel personal<\/h3>\n<p>The impersonator brings up a department, meeting, or executive relationship. The purpose is to make a new account seem connected to an existing responsibility.<\/p>\n<p>Recognizing the meeting can make the whole request feel familiar. The payment details still need their own check.<\/p>\n<p>Separate the two. A correct colleague&#8217;s name doesn&#8217;t validate a new beneficiary. Knowledge of a meeting doesn&#8217;t authorize disclosure of its documents.<\/p>\n<p>Ask how the proposed action would be approved through the normal process. Don&#8217;t let accurate background information substitute for an actual approval.<\/p>\n<h3>Step 4: Urgency and secrecy isolate the employee<\/h3>\n<p>The conversation moves toward a deadline or confidential exception. The employee is encouraged to act before someone else can challenge the request.<\/p>\n<p>Confidentiality can be legitimate. A direction to abandon all identity and payment checks is different, especially when it arrives from an unfamiliar account.<\/p>\n<p>Don&#8217;t debate the sender&#8217;s explanation. Pause and contact the executive&#8217;s office, manager, or authorized approver using information already held by the company.<\/p>\n<p>A quick reply from another account suggested by the same stranger isn&#8217;t independent confirmation. Both ends of that exchange could be controlled together.<\/p>\n<h3>Step 5: The requested action transfers something valuable<\/h3>\n<p>The critical moment is the action: sending money, exposing a sensitive file, or disclosing information that helps someone access an account.<\/p>\n<p>Different conversations can seek different assets. Don&#8217;t assume every attempt ends with the same payment method or a fixed amount.<\/p>\n<p>You don&#8217;t need to wait for a malicious download to recognize the danger. A convincing instruction can cause harm without installing anything.<\/p>\n<p>Once a sensitive action is requested, stop treating the exchange as harmless small talk. Bring the appropriate approval or security team into it.<\/p>\n<h2>How to Verify the Request Without Helping the Impersonator<\/h2>\n<h3>Use an established contact, not a newly supplied number<\/h3>\n<p>Find the executive&#8217;s existing directory entry, an earlier verified internal conversation, or the office contact your organization already uses.<\/p>\n<p>Don&#8217;t call a number pasted into the suspicious chat. That merely lets the same story continue through another channel.<\/p>\n<p>Keep the verification question precise: did this person request this action, involving this recipient, through this account?<\/p>\n<p>A vague question about whether a project exists can produce misleading reassurance. The project may be real while the payment instruction is false.<\/p>\n<h3>Verify the beneficiary separately from the person<\/h3>\n<p>Even an authentic colleague can forward incorrect information. Confirm new payment destinations through your established finance process before sending company funds.<\/p>\n<p>Use the vendor&#8217;s previously recorded contact when checking a change. A phone number printed in the new payment request is part of the unverified material.<\/p>\n<p>If someone says the normal approver is unavailable, follow the organization&#8217;s documented backup process. Don&#8217;t improvise an approval system inside the chat.<\/p>\n<p>Save the conversation for the security team rather than forwarding payment details to uninvolved colleagues. Keep the circle useful and controlled.<\/p>\n<h3>Don&#8217;t use appearance as the deciding test<\/h3>\n<p>A profile picture, polished English, or knowledge of office terminology can make an account seem credible. None replaces an identity check.<\/p>\n<p>Conversely, an external label alone doesn&#8217;t prove fraud. Contractors and business partners legitimately use external accounts, so judge the identity and requested action together.<\/p>\n<p>The practical rule is narrower and stronger: an unexpected account doesn&#8217;t get to bypass a financial or information-access control.<\/p>\n<p>This warning doesn&#8217;t establish that every attempt uses synthetic video, voice cloning, or a compromised executive account. Don&#8217;t wait for those features before responding.<\/p>\n<h2>What to Do if You Have Fallen Victim to This Scam<\/h2>\n<ol>\n<li>\n<p><strong>Stop the instruction and notify your internal security contact.<\/strong> Explain which account contacted you, what it requested, and which actions you completed.<\/p>\n<p>Use the company&#8217;s established reporting route. If you&#8217;re unsure who handles incidents, contact your manager or known IT support rather than the stranger.<\/p>\n<\/li>\n<li>\n<p><strong>If money moved, contact the bank immediately.<\/strong> Tell it the transfer followed an executive-impersonation message and request an urgent fraud assessment.<\/p>\n<p>Have the transaction time, amount, beneficiary, and reference ready. Ask what can still be stopped or recalled; don&#8217;t assume recovery is guaranteed.<\/p>\n<\/li>\n<li>\n<p><strong>Preserve the conversation before blocking it.<\/strong> Save the sender&#8217;s visible address, timestamps, meeting information, instructions, and relevant screenshots for your incident team.<\/p>\n<p>Don&#8217;t delete the only copy because you&#8217;re embarrassed. The record helps investigators identify other recipients and understand how the request reached you.<\/p>\n<\/li>\n<li>\n<p><strong>Report any shared credentials accurately.<\/strong> Tell IT which service the credentials belonged to and whether you approved an unexpected sign-in request.<\/p>\n<p>Follow their instructions for password replacement, session revocation, and authentication review. A password change alone may not address every active session.<\/p>\n<\/li>\n<li>\n<p><strong>List the files and information you disclosed.<\/strong> Identify whether the material included employee details, customer information, financial records, or internal plans.<\/p>\n<p>Let the responsible security and privacy staff decide the next steps. Don&#8217;t privately contact affected customers without coordinating the organization&#8217;s response.<\/p>\n<\/li>\n<li>\n<p><strong>Block and report the account through the appropriate Teams controls.<\/strong> Coordinate with IT if it needs to preserve or investigate the conversation first.<\/p>\n<p>Tell nearby colleagues what to watch for without distributing working payment instructions or sensitive documents in a broad warning.<\/p>\n<\/li>\n<li>\n<p><strong>Document the incident for any bank or police report.<\/strong> Keep the original communications and case references together with the organization&#8217;s incident record.<\/p>\n<p>If someone later offers guaranteed recovery for an upfront fee, don&#8217;t hire them through an unsolicited message. Work through your bank and authorized investigators.<\/p>\n<\/li>\n<\/ol>\n<h2>What Managers Can Do Before the Next Message Arrives<\/h2>\n<p>Make it explicit that employees can verify an executive&#8217;s request without being punished for slowing it down. A safeguard fails when using it feels insubordinate.<\/p>\n<p>Give staff a short, accessible route for unusual instructions. It should still work when the usual approver is traveling or attending a meeting.<\/p>\n<p>Payment controls should apply to senior management too. The phrase \u201cthe CEO asked\u201d mustn&#8217;t become a substitute for documented authorization.<\/p>\n<p>For sensitive files, decide who may approve disclosure and where the approved recipient should receive them. Last-minute chat instructions shouldn&#8217;t silently change that destination.<\/p>\n<p>Ask your Microsoft 365 administrators to review external-contact settings against business needs. Employees shouldn&#8217;t change organization-wide settings in response to one suspicious conversation.<\/p>\n<p>Practice the scenario without shaming anyone who responds. The useful lesson is how an employee pauses and verifies, not who can spot the worst spelling.<\/p>\n<p>Keep verification records separate from the suspicious chat. A genuine instruction can then continue through an approved route without relying on the questionable account.<\/p>\n<p>Don&#8217;t reduce the lesson to avoiding Teams. The same social pressure can move to another workplace app if the underlying approval gap remains.<\/p>\n<h2>If a Confidential File Was Already Shared<\/h2>\n<p>Money isn&#8217;t the only reason to escalate quickly. A confidential spreadsheet can contain information about many people who never saw the original conversation.<\/p>\n<p>Give security the file&#8217;s actual name, location, and sharing method. Sending an attachment and granting access to a cloud file require different containment work.<\/p>\n<p>If you shared a link, ask the authorized administrator to check its permissions and access history. Don&#8217;t assume deleting your chat revokes the recipient&#8217;s access.<\/p>\n<p>If you sent an attachment, changing the original file&#8217;s permissions won&#8217;t retrieve the copy. Tell the incident team exactly which version was sent.<\/p>\n<p>Keep the scope factual. Separate documents actually transmitted from documents merely discussed, and distinguish a confirmed disclosure from something you can&#8217;t yet establish.<\/p>\n<p>For a shared mailbox or finance account, explain who else can act through it. The team may need to review more than your personal sign-in.<\/p>\n<p>Don&#8217;t privately bargain with the sender over deletion. A promise to erase a file doesn&#8217;t establish that every copy has gone.<\/p>\n<p>Authorized security staff can coordinate the response while you preserve records. Your most useful contribution is an accurate timeline, not a solo attempt to investigate.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<h3>Is Microsoft Teams itself a scam?<\/h3>\n<p>No. Teams is a legitimate communication service. This scam involves an impersonator abusing its messaging or meeting features to borrow an executive&#8217;s authority.<\/p>\n<h3>Does an external label mean the message is fraudulent?<\/h3>\n<p>Not by itself. It means you should establish why that external account is making an internal request, especially if payment or sensitive information is involved.<\/p>\n<h3>What if the sender knows private-sounding company details?<\/h3>\n<p>Treat the instruction as unverified until you confirm it independently. Some convincing details are public; others may have reached the sender through unrelated channels.<\/p>\n<h3>Should I ask the sender to prove who they are?<\/h3>\n<p>You can stop the conversation without negotiating proof. Contact the real person&#8217;s established office or account instead of accepting documents or contacts the stranger supplies.<\/p>\n<h3>Do I need to scan my computer after reading the chat?<\/h3>\n<p>Reading a payment request doesn&#8217;t establish malware infection. If you also opened files or installed software, tell your IT team exactly what happened.<\/p>\n<h3>Can a company recover money sent after a fake CEO instruction?<\/h3>\n<p>Possibly, but timing and the payment&#8217;s status matter. Contact the bank immediately and preserve the chat; nobody can honestly promise recovery from the conversation alone.<\/p>\n<h2>The Bottom Line<\/h2>\n<p>Don&#8217;t send money or confidential information because an unexpected Teams account uses your boss&#8217;s name. Confirm the exact instruction through an established company contact.<\/p>\n<p>If you already acted, notify security and, for payments, the bank immediately.
