QUITO (Reuters) - Hacking attempts on Ecuadorean government institutions have doubled since the country revoked WikiLeaks founder Julian Assange’s asylum at its London embassy last week, an official said on Monday. Telecommunications Vice Minister Patricio Real told reporters the websites for the country’s presidency, central bank and foreign ministry, among others, has received 40 million hacking attempts per day since Assange was dragged out of the embassy on Thursday by London police. Real did not attribute the hacking attempts to any group in particular, and said it would be difficult to identify the hackers. But he said the hacking group Anonymous, which has taken credit for cyberattacks on government institutions in the United States and Britain, had made a threat. Real said the hacking attempts had not led to the theft of any government data, but had made it difficult for employees and citizens to access accounts on the sites. On Saturday, an Ecuadorean judge ordered a Swedish citizen close to Assange jailed pending trial for alleged involvement in hacking government computer systems.
