Technical writeup
Baker Hughes was publicly named among multinational oilfield services / exploration firms targeted in the “Night Dragon” long-running intrusions publicized by McAfee in February 2011, with spear-phishing from Chinese IP space and theft of field-systems descriptions, oil-bid intelligence, and operational project detail called out in contemporaneous Reuters, CSMonitor, and Computer Weekly reporting. Incident narratives focused on industrial espionage rather than mass consumer PII leaks.
