The release of documents that purportedly describe hacking of consumer gadgets by the Central Intelligence Agency fueled new concern in the technology industry that U.S. intelligence agencies are working at odds with tech companies. WikiLeaks said the 8,761 documents and files it made public Tuesday describe techniques the CIA uses to circumvent the security of dozens of products, including mobile phones from Apple Inc. If accurate, the documents could point to new security weaknesses for the products and their customers – although some experts on Tuesday said the techniques described in the documents don’t appear especially sophisticated.
