Advertisement“There were no security measures,” that contractor, who was based out of Beijing, told the Guardian. “I don’t even remember them doing proper KYC [know your customer] on me. I think they just took my Chinese bank account details.”While that contractor worked out of the office initially, he told the Guardian that Microsoft “after a while allowed me to do it from home in Beijing. I judged British English (because I’m British), so I listened to people who had their Microsoft device set to British English, and I had access to all of this from my home laptop with a simple username and password login... They just give me a login over email and I will then have access to Cortana recordings. I could then hypothetically share this login with anyone.”

As with similar programs run by Apple, Amazon, , and Google, the recordings sometimes captured intimate, embarrassing, or potentially compromising situations ranging from phone sex and pornographic search queries to what the contractor told the Guardian was possible domestic violence. As the paper noted, while users were informed audio could be captured for analysis, Microsoft did not disclose that actual human beings were listening to the audio.The lax security measures are particularly concerning because the Chinese government is a mass surveillance state that tightly controls and monitors online communications. Freedom House ranks it as “the world’s worst abuser of internet freedom for the fourth consecutive year,” a situation Chinese security services “pushed to unprecedented extremes as the government enhanced its information controls” in 2019.

The work is now carried out by facilities outside of China. However, Microsoft did not address questions about whether personnel other than reviewers based out of China had access to more extensive voice recordings or whether the information was stripped of identifying information before or after it arrived in the country.

We’ve always disclosed this to customers and operate to the highest privacy standards set out in laws like Europe’s GDPR.”
“This past summer we carefully reviewed both the process we use and the communications with customers,” the spokesperson added. “As a result we updated our privacy statement to be even more clear about this work, and since then we’ve significantly enhanced the process including by moving these reviews to secure facilities in a small number of countries. We will continue to take steps to give customers greater transparency and control over how we manage their data.”
