Microsoft Teams Users Targeted by Dangerous Caller ID Spoofing Scams

Microsoft Teams is facing an uptick in caller ID spoofing scams where attackers impersonate trusted colleagues by changing their display names during calls. The VUMC Enterprise Cybersecurity (VEC) has reported instances where users received calls appearing to come from their supervisors, only for the display name or number to shift after answering. This manipulation often leads recipients to comply with suspicious requests, such as software installations or financial transactions, under the pretense of urgency. To mitigate these risks, individuals are advised to verify caller identities through independent means and to avoid engaging with unsolicited calls.
