Ralph Langner a German cyber-security researcher has speculated that the Stuxnet computer worm that includes a programmable logic controller targeting industrial equipment with the capability to reprogram and then hide its changes, may have been unwittingly spread to Iranian Nuclear facilities from USB drives belonging to Russian contractors. Iran has confirmed that its nuclear program using Siemens control systems had been damaged by the Stuxnet worm. Israel has been credited with the ability to not only create the Stuxnet worm but also to test it on former Libya’s centrifuges obtained from the USA and installed at its own Dimona nuclear complex in the Negev desert. There appears to be little downside to such an attack from Israel as it is virtually impossible to prove who did it.
