January 20, 2010 Evidence Found for Chinese Attack on Google By JOHN MARKOFF NY Times
http://www.nytimes.com/2010/01/20/technology/20cyber.html?ref=business&pagewanted=print SAN FRANCISCO — An American computer security researcher has found what he says he believes is strong evidence of the digital fingerprints of Chinese authors in the software programs used in attacks against Google. The search engine giant announced last Tuesday that it had experienced a series of Internet break-ins it believed were of Chinese origin. The company’s executives did not, however, detail the evidence leading them to the conclusion that the Chinese government was behind the attacks, beyond stating that e-mail accounts of several Chinese human rights activists had been compromised. In the week since the announcement, several computer security companies have made claims supporting Google’s suspicions, but the evidence has remained circumstantial. Now, by analyzing the software used in the break-ins against Google and dozens of other companies, Joe Stewart, a malware specialist with SecureWorks, a computer security company based in Atlanta, said he determined the main program used in the attack contained a module based on an unusual algorithm from a Chinese technical paper that has been published exclusively on Chinese-language Web sites. The malware at the heart of Google attack is described by researchers as a “Trojan horse” that is intended to open a back door to a computer on the Internet. The program, called Hydraq by the computer security research community and intended to subvert computers that run different versions of the Windows operating system, was first noticed earlier this year. Mr. Stewart describes himself as a “reverse engineer,” one of a relatively small group of software engineers who disassemble malware codes in an effort to better understand the nature of the attacks that have been introduced by the computer underground, and now possibly by governments as well. “If you look at the code in a debugger you see patterns that jump out at you,” he said. In this case he discovered software code that represented an unusual algorithm, or formula, intended for error-checking transmitted data. He acknowledged that he could not completely rule out the possibility that the clue had been placed in the program intentionally by programmers from another government intent on framing the Chinese, but he said that was unlikely. “Occam’s Razor suggests that the simplest explanation is probably the best one.” -- ================================ George Antunes, Political Science Dept University of Houston; Houston, TX 77204 Voice: 713-743-3923 Fax: 713-743-3927 Mail: antunes at uh dot edu *********************************** * POST TO [email protected] * *********************************** Medianews mailing list [email protected] http://lists.etskywarn.net/mailman/listinfo/medianews
