Espionage

When Alan Turing cracked the Enigma code during the Second World War, neither the United Kingdom nor the United States immediately published a paper announcing the achievement. Instead, they kept it to themselves so they could keep reading Nazi messages encrypted using Engima machines. Last month, in contrast, Chinese academics from government-run laboratories and research organizations published a paper claiming to have developed a new mathematical strategy to break RSA encryption, today’s standard.

If the Chinese government can crack RSA encryption, then they can break into every U.S. government and private sector system, seeing and exfiltrating anything and everything, achieving true information dominance over Washington and its allies and partners.

SINGAPORE—China’s top nuclear-weapons research institute has bought sophisticated U.S. computer chips at least a dozen times in the past two and half years, circumventing decades-old American export restrictions meant to curb such sales.

A Wall Street Journal review of procurement documents found that the state-run China Academy of Engineering Physics has managed to obtain the semiconductors made by U.S. companies such as Intel Corp. and Nvidia Corp. since 2020 despite its placement on a U.S. export blacklist in 1997.

It was an innocuous-looking photograph that turned out to be the downfall of Zheng Xiaoqing, a former employee with energy conglomerate General Electric Power.

According to a Department of Justice (DOJ) indictment, the US citizen hid confidential files stolen from his employers in the binary code of a digital photograph of a sunset, which Mr Zheng then mailed to himself.

It was a technique called steganography, a means of hiding a data file within the code of another data file. Mr Zheng utilised it on multiple occasions to take sensitive files from GE.
