Minor cyber rioting flares anew in South Asia as Pakistani and Indian patriotic hacktivists take swipes at each other's online institutions.

CloudFlare reports sustaining a denial-of-service attack on its infrastructure, with traffic apparently originating from China.

Last week's reports of Chinese cyber attacks on US businesses and government agencies are joined by complaints from Chinese dissidents that their own online presence is under unremitting attack by China's government.

These reports did not prevent the US and China from reaching a certain limited accord at last week's summit. Both countries undertake not to "conduct or knowingly support cyber-enabled theft of intellectual property" for purposes of giving domestic companies competitive advantages (which observers note is nice but full of loopholes — some would have preferred "knowingly tolerate"). More significantly, the two countries agreed to establish on-going coordination (reminding some of Cold War era hotlines) and potential law enforcement cooperation. For its part the US leaves the possibility of sanctions on the table, but with some assurance these would, if enacted, be narrowly targeted against companies and individuals.
