Microsoft Teams Has Become a Haven for Scammers in China

Scammers in China are exploiting trusted enterprise communication apps (Microsoft Teams, Cisco Webex, and Zoho Cliq) to carry out social-engineering fraud: creating organization-controlled accounts, supplying login credentials, and using features such as screen sharing and remote control to defraud victims across recruitment, dating, rental, and procurement contexts; victims and app-store reviews report numerous incidents, and vendors have taken mitigations (Zoho disabled payments and suspended accounts; Microsoft added safety banners).
