Zhao, a woman from Beijing, lost over $100,000 in May to a scammer who pretended to be a Microsoft researcher. Their communication initially started on Xiaohongshu, but the scammer convinced her to switch to Microsoft Teams, assuring her of a safe platform. Trusting the app because of its Microsoft branding, she began investing in a promising cryptocurrency scheme he presented.
After taking out multiple loans to increase her investment, Zhao’s world came crashing down when the scammer disappeared, taking all her money and accessing her Teams account just long enough to erase any evidence of their chats. As she shared her story online, Zhao discovered numerous other victims of similar scams, leading to losses ranging from $1,500 to $300,000, with only one instance of a victim recovering funds by tracking the scammer’s bank account.
Many victims shared a common experience of being directed to use Microsoft Teams, which has prompted law enforcement in China to issue public warnings specifically mentioning the app as a tool for fraudulent activities. Some victims took to app stores to express their frustration, with over 30% of the reviews on Chinese versions of Teams highlighting scams. Reviews dating back to 2022 echoed Zhao’s story, with warnings about being defrauded through Teams.
In response to the rising scams, Microsoft has acknowledged the exploitation of its platform for such schemes. The company has begun displaying warnings to users in China about typical scams and has ceased the personal version of Teams within the country, limiting availability to enterprise accounts only.
Scam operations have not been limited to Teams; platforms like Webex and Zoho Cliq have also been implicated. Victims have reported similar tactics, leading to public outcry on social media. In tracking victims’ accounts, patterns emerged where scammers targeted individuals through various channels—posing as recruiters, renters, or even on dating apps—before transitioning them to Microsoft Teams.
Once on Teams, victims were provided login details that the scammers controlled, allowing them to erase conversations once they ceased communication. Zhao, in an attempt to extract more information from her original scammer, initiated another interaction under a different identity. Discovering that the scammer continued the same narrative, she recognized the extent of the manipulation at play.
Zhao remarked on the inadequate support from Teams during her initial interaction with the scammer, noting that Microsoft only began issuing warnings in subsequent interactions. The appeal of Microsoft Teams as a preferred platform for fraud stems from its accessibility—unlike other messaging apps, it’s not blocked by the Chinese government and has advanced features that scammers exploit.
As fraudulent activities proliferate across various communication platforms, there’s a growing need for better protective measures and user education to combat these complex and evolving scams.
