The Wikileaks website says it has evidence that a number of senior Brazilian government officials were routinely spied on by the National Security Agency in the United States. It says the NSA was particularly active in economic espionage against Brazil.

Wikileaks published a list of 29 phone numbers of Brazilians in banking, finance and the economy. According to the website the espionage apparently began in early 2011 or even earlier. President Dilma Rousseff cancelled a state visit to Washington two years ago when former CIA contractor Edward Snowden revealed that her phones and emails were being spied on.

A Brazilian judge has called for Apple and Google to remove the anonymous social network Secret from their app stores and wipe it from phones on which it has already been installed across the country.

The San Francisco startup has come under fire from those charging that Secret and other anonymous apps too easily become sanctuaries for cyberbullying. Last week, a San Diego man started a Change.org petition seeking to remove Secret from Apple and Android app stores, though the petition had little support. On Monday, an opinion piece in the New York Times argued that anonymous apps and Internet websites such as Secret often make women and minorities a target for attack.

National Security Agency leaker Edward Snowden wrote in a lengthy "open letter to the people of Brazil" that he's been inspired by the global debate ignited by his release of thousands of National Security Agency documents, and that the NSA's culture of indiscriminate global espionage "is collapsing."

In the letter, released widely online, Snowden commended the Brazilian government for its strong stand against U.S. spying. He said he'd be willing to help the South American nation investigate NSA spying on its soil, but could not fully participate in doing so without being granted political asylum, because the U.S. "government will continue to interfere with my ability to speak."
