Microsoft Teams Has Become a Haven for Scammers in China
Microsoft Teams has reportedly become a commonly used tool in China for “pig-butchering” investment scams, in which fraudsters build trust before persuading victims to put money into fake cryptocurrency schemes. The cases matter because scammers exploit the credibility of familiar workplace software, and victims can lose access to chat records when accounts controlled by criminals disappear.
Victims described losses ranging from $1,500 to $300,000, often after being told to download Teams and use credentials supplied by the scammer; WIRED found that 30 percent of 500 recent Chinese App Store reviews mentioned scams. Microsoft introduced a scam-warning banner for Teams users in China in June and ended the personal version there, while similar complaints have involved Webex and Zoho Cliq; Zoho said it had suspended accounts linked to suspected fraudsters.
In short
- Scammers in China are exploiting trusted workplace messaging apps.
- Teams victims reported losses of up to $300,000.
- Microsoft has added warnings and restricted Teams’ availability.
Explained simply
Pig-butchering scams involve fraudsters building a relationship with someone over time, then steering them towards a fake investment, often involving cryptocurrency. The name refers to the way victims are gradually drawn in before being persuaded to put in money.
Scammers may move conversations to familiar workplace chat services such as Microsoft Teams, which can make the contact seem more credible. They may provide login details or control the accounts themselves; if those accounts disappear, victims can lose access to messages that might help explain what happened.
The issue sits within a wider challenge for online services: allowing people to communicate while identifying and removing accounts used for fraud. Similar complaints have involved other chat platforms, including Webex and Zoho Cliq.
