嗯，用户让我总结一下这篇文章的内容，控制在一百个字以内，而且不需要用“文章内容总结”之类的开头。好的，首先我需要仔细阅读这篇文章，理解其主要信息。 文章讲的是微软向FBI提供了三台加密笔记本电脑的恢复密钥，这些笔记本电脑涉及一起与疫情失业援助计划有关的欺诈调查。BitLocker是Windows的全盘加密技术，默认情况下会将恢复密钥上传到微软的云服务器，这样微软和执法机构就能获取这些密钥来解密数据。专家担心这可能带来隐私风险，尤其是如果黑客攻击了微软的云基础设施，可能会获取这些密钥。 接下来，我需要把这些信息浓缩到一百个字以内。首先提到微软提供恢复密钥给FBI，涉及欺诈调查。然后说明BitLocker默认上传密钥到微软云，导致执法机构可以获取。最后提到专家对隐私和安全的担忧。 现在组织语言：微软向FBI提供三台加密笔记本电脑的恢复密钥，用于一起欺诈调查。BitLocker默认上传密钥至微软云，使执法机构可获取。专家担忧隐私和安全风险。 检查字数：刚好在一百字左右。确保没有使用“文章内容总结”之类的开头，并且直接描述内容。 </think> 微软向FBI提供了三台加密笔记本电脑的恢复密钥，用于一起欺诈调查。BitLocker默认上传密钥至微软云，使执法机构可获取。专家担忧隐私和安全风险。 2026-1-23 16:46:56 Author: techcrunch.com(查看原文) 阅读量:0 收藏
Microsoft provided the FBI with the recovery keys to unlock encrypted data on the hard drives of three laptops as part of a federal investigation, Forbes reported on Friday.
Many modern Windows computers rely on full-disk encryption, called BitLocker, which is enabled by default. This type of technology should prevent anyone except the device owner from accessing the data if the computer is locked and powered off.
But, by default, BitLocker recovery keys are uploaded to Microsoft’s cloud, allowing the tech giant — and by extension law enforcement — to access them and use them to decrypt drives encrypted with BitLocker, as with the case reported by Forbes.
The case involved several people suspected of fraud related to the Pandemic Unemployment Assistance program in Guam, a U.S. island in the Pacific. Local news outlet Pacific Daily News covered the case last year, reporting that a warrant had been served to Microsoft in relation to the suspects’ hard drives. Kandit News, another local Guam news outlet, also reported in October that the FBI requested the warrant six months after seizing the three laptops encrypted with BitLocker.
A spokesperson for Microsoft did not immediately respond to a request for comment by TechCrunch. Microsoft told Forbes that the company sometimes provides BitLocker recovery keys to authorities, having received an average of 20 such requests per year.
Apart from the privacy risks of handing recovery keys to a company, Johns Hopkins professor and cryptography expert Matthew Green raised the potential scenario where malicious hackers compromise Microsoft’s cloud infrastructure — something that has happened several times in recent years — and get access to these recovery keys. The hackers would still need physical access to the hard drives to use the stolen recovery keys.
“It’s 2026 and these concerns have been known for years,” Green wrote in a post on Bluesky. “Microsoft’s inability to secure critical customer keys is starting to make it an outlier from the rest of the industry.”
