History

Historical Context

In June 2010 Stuxnet—a US-Israel cyber weapon from Operation Olympic Games—crippled Iran’s Natanz plant, destroying about 1,000 centrifuges. The attack showed malware could hijack control systems, a threat that underlies the August 21 2026 boarding of the Liberian-flagged VL Prosperity after an Iranian intrusion altered its engine-room cooling and fuel systems. U.S. Coast Guard and FBI agents seized the vessel to prevent further sabotage.
