More information has come to light on government surveillance, with new information revealing a campaign by the CIA to break through security on devices from Apple and Microsoft. Researchers working with the agency would apparently present their latest efforts at a yearly meeting called the "Jamboree". In 2010, a group of attendees announced that they were able to extract BitLocker encryption keys, according to The Intercept:

Also presented at the Jamboree were successes in the targeting of Microsoft's disk encryption technology, and the TPM chips that are used to store its encryption keys. Researchers at the CIA conference in 2010 boasted about the ability to extract the encryption keys used by BitLocker and thus decrypt private data stored on the computer. Because the TPM chip is used to protect the system from untrusted software, attacking it could allow the covert installation of malware onto the computer, which could be used to access otherwise encrypted communications and files of consumers. Microsoft declined to comment for this story.

Microsoft was one of the many tech companies calling for mass surveillance programs to be curbed. The company has also resisted efforts by the U.S. government to obtain emails stored on servers in Ireland, receiving support from companies like Apple, Amazon, and Verizon.
