U.S. counterintelligence chief skeptical China has curbed spying on U.S.

U.S. counterintelligence chief Bill Evanina said on Wednesday he was skeptical China had followed through on recent promises to curb spying on the United States.

Evanina told a briefing that he had seen "no indication" from the U.S. private sector "that anything has changed" in the extent of Chinese espionage on the United States.

He said 90 percent of private sector and government data systems intrusions are enabled by "spear-phishing," adding that spear-phishing played a role in the massive hack of security clearance data from the U.S. Office of Personnel Management (OPM).
