PRISM scandals 棱鏡門 (leng jing men)

Earlier this month, Edward Snowden, a former CIA agent and contractor with the US' National Security Agency flew from Hawaii to Hong Kong and offered classified US government documents to media outlets, including London-based The Guardian. The documents revealed the existence of a high-level clandestine NSA surveillance program codenamed PRISM.

Whistleblower Snowden told the South China Morning Post that the NSA has conducted more than 61,000 hacking operations across the globe, and Hong Kong and the Chinese mainland have been on the target list for years.
