Langner was among the first independent researchers who argued that Stuxnet was designed to attack a specific target, namely: the Iranian nuclear facility at Natanz. Within recent weeks, his theory has been given a boost after the office of Iranian President Mahmoud Ahmadinejad issued publicity photos of the Presidents visit to the facility. Included in the photos, inadvertantly, were shots of computer screens used to manage the centrifuges used for uranium enrichment. Those photos, Langner claims, confirm that the design of the facility there corresponds exactly to the design.”]
