French users of Microsoft services are being shown ads that redirect them to scam surveys, polls, or other unwanted promotions. These ads are also able to escape Microsoft games to load the scam ads in the default browser used by Windows. The ads are filtering out VPNs and are focusing on residential IP addresses of users in France. Microsoft has reached out to Microsoft about this ad campaign and will update the story when we receive a response from the company. It is important to note that if you are being redirected to these types of scams from Microsoft services or games, you are not infected.
