By Jeremy Wagstaff SINGAPORE (Reuters) – Twenty-one of the worlds top-25 news organizations have been the target of likely state-sponsored hacking attacks, according to research by two Google security engineers. While many internet users face attacks via email designed to steal personal data, journalists were massively over-represented among such targets, said Shane Huntley, a security software engineer at Google. The attacks were launched by hackers either working for or in support of a government, and were specifically targeting journalists, Huntley and co-author Morgan Marquis-Boire said in interviews. Their paper was presented at a Black Hat hackers conference in Singapore on Friday.
