Security firm: Hackers hit chemical companies

Cyber attacks traced to China targeted at least 48 chemical and military-related companies in an effort to steal technical secrets, a U.S. computer security company said Tuesday, adding to complaints about pervasive Internet crime linked to this country.

The targets included 29 chemical companies and 19 others that make advanced materials used by the military, California-based Symantec Corp. said in a report. It said the group included multiple Fortune 100 companies but did not identify them or say where they were located.

"The purpose of the attacks appears to be industrial espionage, collecting intellectual property for competitive advantage," said the report.
