According to a report by Industrial Safety and Security Source (ISS
Source), which cites US intelligence sources, Israel's foreign
intelligence agency Mossad used a worker at Iran's Natanz uranium
enrichment facility to infiltrate the Stuxnet worm into the facility.
The officials told the news site that the worker was of Iranian origin
and used a specially crafted USB flash drive to load the malware onto
the Natanz systems. The worker is said to have probably belonged to an
opposition group.

Mossad is also reported to have used double agents to identify weak
points in the facility in order to improve its chances of success. The
report says that these agents were probably members of the militant
Iranian opposition movement Mujahideen-e Khalq (MEK).

In the summer of 2010, Stuxnet made headlines because it exploited
previously unknown security vulnerabilities in Windows, was signed
with a valid certificate, and appears to have been specially developed
to attack the uranium enrichment facility in Natanz.
