The double agent was able to load the worm onto a memory stick and directly upload it to a system on the network. Once activated, it infiltrated the entire network and took over systems vital to the facility’s operations. These new revelations come from current and former U.S. intelligence officials who have asked to remain anonymous due to their proximity to ongoing investigations, according to the report.
The Stuxnet virus was a computer worm created jointly by the United States and Israel, designed to infiltrate and disrupt Iran’s nuclear program. The worm is widely regarded as the most sophisticated of its type ever developed. It remained untraceable by anti-virus software, and took Iranian security researchers several months to deconstruct, analyze and fully understand its purpose.
When the time was right, Stuxnet deployed its payload which only targeted Siemens supervisory control and data acquisition (SCADA) systems and other select systems. The goal of the attack was to damage the centrifuges used to enrich uranium for nuclear use.
