Microsoft Teams is reportedly being exploited by scammers in China, with victims losing significant sums of money through romance and investment fraud schemes. The platform's legitimacy, combined with its features, makes it an attractive tool for fraudsters targeting unsuspecting users.
One victim, a woman from Beijing who asked to be identified only by her last name, Zhao, lost over $100,000 to a romance scammer who initially connected with her on Xiaohongshu before moving the conversation to Microsoft Teams. The scammer promised a future together and enticed her into a cryptocurrency investment, which ultimately led to her financial ruin. Because the scammer controlled the Teams account used for the scheme, Zhao was unable to retrieve chat logs to provide to the police.
Zhao's experience is not isolated. She discovered dozens of others in China who fell victim to similar scams, reporting losses ranging from $1,500 to $300,000. The common thread involves scammers instructing victims to download Microsoft Teams and use login credentials they provide. This has become so prevalent that some Chinese law enforcement agencies have issued warnings, explicitly naming Teams as a tool used in fraud.
Reviews on Chinese app stores reflect these concerns, with a significant percentage of Microsoft Teams reviews mentioning scams. One review from January detailed a "pig-butchering" scam that cost the user approximately $220,000. Microsoft has stated that scammers frequently exploit trusted brands and platforms, and that they investigate abuse reports and strengthen protections against fraudulent activity. They have also begun displaying warning banners to Teams users in China and have discontinued the personal version of Teams in the country, limiting its availability to enterprise accounts.
While Teams is a primary concern, similar issues have been reported with other corporate communication tools like Cisco's Webex and Zoho's Cliq. Scammers leverage these platforms by creating accounts for victims and providing credentials, allowing them to control the narrative and wipe out evidence by deactivating accounts post-scam. The legitimate nature of these Western platforms, coupled with the fact that they are not blocked by the Chinese government, makes them appealing alternatives to domestic apps that may have more robust fraud detection.
