mendax points out a story at the NY Times about evidence that the Australian Signals Directorate notified the NSA in 2013 that it was spying on discussions between Indonesia and an American law firm
. The information gathered by the Directorate included material covered by attorney-client privilege. The Times says:
"Most attorney-client conversations do not get special protections under American law from N.S.A. eavesdropping. Amid growing concerns about surveillance and hacking, the American Bar Association in 2012 revised its ethics rules to explicitly require lawyers to 'make reasonable efforts' to protect confidential information from unauthorized disclosure to outsiders. ... Several newly disclosed documents provide details of the cooperation between the United States and Australia, which share facilities and highly sensitive intelligence, including efforts to break encryption and collect phone call data in Indonesia. Both nations have trade and security interests in Indonesia, where Islamic terrorist groups that threaten the West have bases."
