北京一名赵姓女子在五月遭遇网路交友诈骗，损失超过十万美元。诈骗者自称是微软研究员，在社群平台搭讪后，要求将对话转移到 Microsoft Teams，并提供帐号密码给她使用。由于微软是知名大企业，赵女士降低了戒心，最终被说服贷款投资加密货币，随后诈骗者卷款潜逃并删除了她的帐号，导致她无法取得对话纪录报警。（关键数字：100,000）

赵女士的经历并非个案，中国各地有数十名受害者遭遇相同手法的诈骗，损失金额从数千到数十万美元不等。诈骗集团利用 Teams、Webex 和 Cliq 等企业通讯软体进行诈骗，他们会伪装成面试官、房东或交友对象寻找目标。这些软体在中国未被封锁，且具备萤幕分享等进阶功能，加上由诈骗者控制企业帐号，让他们能轻易在事后销毁证据。

相较于微信等中国本土通讯软体会积极侦测敏感关键字并主动发出防诈骗警告，西方企业软体在防范此类诈欺上显得准备不足。在大量使用者投诉与警方警告后，微软于六月开始在中国版 Teams 显示防诈骗警告标语，并停止提供个人版服务，而其他如 Zoho Cliq 也暂停了中国区的线上支付及免费版本，以遏止诈骗蔓延。

A woman in Beijing surnamed Zhao lost over $100,000 in May to a romance scammer posing as a Microsoft researcher. After connecting on a social media platform, the scammer persuaded her to move their conversations to Microsoft Teams, providing her with login credentials. Trusting the reputable brand, she was lured into a cryptocurrency investment scheme, only for the scammer to disappear with her money and revoke her account access, destroying all chat logs.

Zhao's experience is not isolated, as dozens of other victims across China have reported falling prey to the exact same scheme, losing anywhere from a few thousand to hundreds of thousands of dollars. Scammers increasingly exploit enterprise communication tools like Teams, Webex, and Cliq, posing as recruiters, landlords, or potential dates. These apps are not blocked in China and offer advanced features like screen sharing, while allowing scammers to control the organization accounts and effortlessly erase evidence afterward.

Compared to domestic Chinese apps like WeChat that actively detect sensitive keywords and issue warnings to users, Western enterprise software platforms appear less prepared to combat these investment frauds. Following a surge of user complaints and police warnings, Microsoft began displaying scam warnings on Teams in China in June and discontinued its personal version. Similarly, other platforms like Zoho Cliq have disabled online payments and suspended free versions in China to curb the rampant fraudulent activity.
