Impersonation Reports for 02 8880 5708

One contributor has reported a suspicious call from 02 8880 5708 (also written as 0288805708) involving impersonation. The caller attempted to reach the contributor's work number through Microsoft Teams, presenting themselves as if they were part of the organisation. However, the Teams system identified them as external to the company, immediately flagging the attempted deception.

This type of impersonation targeting workplace communication systems is particularly concerning because it exploits the trust associated with internal communication platforms. The fact that 0288805708 was calling through Teams suggests the caller may have had the organisation's phone number or contact information, or was attempting a broader campaign against that business.

What the Caller from 02 8880 5708 Was Attempting

The contributor reported that the call from 02 8880 5708 came through Teams with the caller posing as an internal team member or organisation affiliate. Teams' built-in security system prevented the impersonation from succeeding by clearly marking the caller as external to the organisation, which allowed the contributor to immediately recognise the attempt as fraudulent.

This approach differs from traditional phone spoofing because it targets corporate communication infrastructure rather than personal phone lines. Attackers using this method may be attempting to gain access to company systems, extract sensitive business information, or establish rapport before escalating to financial or credential requests.
