An Associated Press investigation revealed last week that the US Agency for International Development program used the data to build a subscriber base for the platform, dubbed ZunZuneo, with the idea that it could be used to stir unrest.
Cuba considers such USAID programs to be subversive attempts to topple its Communist-run government. Officials told reporters that state telecom Etecsa had not provided the data to any international operator or entity, and that the information was obtained illegally.
Washington officials have defended the ZunZuneo program as consistent with US law and described it as "discreet," rather than covert or classified. Rep. Ileana Ros-Lehtinen, a Cuban-born Republican from Florida, called US-led democracy efforts in Cuba "transparent" and "one of the most scrutinized programs in our foreign aid portfolio."
Ramos said Etecsa detected bulk messages being sent during the ZunZuneo project starting in September 2009 during a concert by Colombian singer Juanes, and again in early 2010.

Etecsa had no idea the messages were anything other than unwanted spam, Ramos said.
It was only recently that "we learned this was more than an operator issue," he said.
The Caribbean country's government controls nearly all print, TV and radio outlets. Internet access is rare, restricted, slow and prohibitively expensive for most Cubans. Authorities say the country has little bandwidth to spare and must prioritize Internet access for use deemed in the public interest.
