An employee receives a Microsoft Teams call from someone who appears to work in IT. The caller says there is an urgent account or computer problem and asks the employee to open Microsoft Quick Assist.
Because Quick Assist is a legitimate Windows support tool, the request may not look dangerous. However, Microsoft reported on October 30, 2026, that attackers have been impersonating help-desk personnel through Teams messages and calls, then persuading employees to approve remote access.
Once the connection is approved, the person on the other end may be able to view the screen, control the computer, transfer files, or install additional software.
For a small business without a large internal IT department, that can turn one convincing phone call into stolen data, compromised accounts, and significant downtime.
Quick Assist is a real Microsoft application that allows one person to remotely view or control another person’s computer. It is useful when a trusted technician is helping an employee solve a problem.
The danger is not necessarily a flaw in Quick Assist. The danger comes from allowing the wrong person to connect.
Microsoft advises users to permit a Quick Assist connection only when they initiated the support interaction by contacting Microsoft or their own IT provider directly.
The caller may claim that:
The caller may know an employee’s name, company, job title, or email address. They may also use a convincing display name in Teams.
These details do not prove the caller is legitimate. Information about employees and companies is often available through websites, social media, previous data breaches, and public business records.
Employees should not approve remote access in response to an unexpected call, chat, email, or pop-up. A sense of urgency is a reason to slow down, not speed up.
End the call and contact the company’s IT provider using a saved phone number, support portal, or internal directory. Do not use a phone number or link supplied by the caller.
Caller ID and Teams display names can be misleading.
A connection code is effectively a key that can open the computer to remote support. Employees should treat it with the same care as a password or sign-in approval.
Quick Assist asks the user to approve screen sharing and may request permission for full control. Employees should never click Allow simply because someone is guiding them over the phone.
Even when an employee does not approve the connection, reporting the attempt helps the company warn other staff and check whether several people are being targeted.
Employees should feel comfortable reporting a suspicious call without worrying that they will be blamed.
A simple remote-support policy can remove much of the uncertainty. Employees should know:
Businesses that use another remote-support platform should also ask their IT provider whether Quick Assist is needed. Microsoft recommends disabling or removing it when an organization does not use it.
Microsoft Teams external-access settings should be reviewed as well. Businesses can limit outside communication when unrestricted external contact is unnecessary.
Disconnect the remote session immediately and contact your trusted IT provider from another device if possible.
Do not continue signing into email, banking, payroll, or other business systems until the computer and affected accounts have been reviewed. Your IT provider may need to inspect the computer, remove unauthorized access, review Microsoft 365 activity, revoke active sessions, and reset affected credentials.
Write down what happened, including the caller’s name, displayed account, time of contact, instructions given, and any websites or applications opened. Those details can help the investigation.
Employees do not need to recognize every new scam. They need one dependable habit: unexpected support requests must be independently verified before anyone shares information or allows access.
