U.S. government analysts believe a Chinese man with government links wrote the key part of a spyware program used in hacker attacks on Google last year, the Financial Times reported on Monday.
The man, a security consultant in his 30s, posted sections of the program to a hacking forum where he described it as something he was "working on," the paper said, quoting an unidentified researcher working for the U.S. government.
I think further research may be required. Hopefully someone interviews the guy. (Unlikely, of course.)
