Today I read very interesting
article on The New York Times webite. Below is some parts of that article. Hope you will like it.
Iran's Nuclear Facilities
Stuxnet is the name given to a computer worm, or malicious computer program, that began to spread in mid-2009. It may the most sophisticated cyber weapon ever deployed.
Stuxnet turned up in industrial programs around the world. But experts dissecting it soon determined that it had been precisely calibrated in a way that would send nuclear centrifuges wildly out of control, adding to suspicions that it was meant to sabotage Iran’s nuclear program.
It appears to have wiped out roughly a fifth of Iran’s nuclear centrifuges and helped delay, though not destroy, Tehran’s ability to make its first nuclear arms. After its spread, intelligence officials began to talk of setbacks in Iran's program that could delay the day it is able to produce a nuclear weapon.
Many mysteries remain, chief among them, exactly who constructed a computer worm that appears to have several authors on several continents. But the digital trail is littered with intriguing bits of evidence, many of which suggest that the virus was designed as an American-Israeli project to sabotage the Iranian program.
The worm itself now appears to have included two major components. One was designed to send Iran’s nuclear centrifuges spinning wildly out of control. Another seems right out of the movies: The computer program also secretly recorded what normal operations at the nuclear plant looked like, then played those readings back to plant operators, like a pre-recorded security tape in a bank heist, so that it would appear that everything was operating normally while the centrifuges were actually tearing themselves apart.

The attacks were not fully successful: Some parts of Iran’s operations ground to a halt, while others survived, according to the reports of international nuclear inspectors. Nor is it clear the attacks are over: Some experts who have examined the code believe it contains the seeds for yet more versions and assaults.
Dimona Nuclear Facility
The Dimona complex in the Negev desert, the heavily guarded heart of Israel’s never-acknowledged nuclear arms program, became a critical testing ground in a joint American and Israeli effort to undermine Iran’s efforts to make a bomb of its own.
Behind Dimona’s barbed wire, the experts say, Israel spun nuclear centrifuges virtually identical to Iran’s at Natanz, where Iranian scientists are struggling to enrich uranium. They say Dimona tested the effectiveness of the computer worm, a critical step in honing its effectiveness.
The paternity of the worm is still in dispute, but officials from Israel have broken into wide smiles when asked whether Israel was behind the attack, or knew who was. Several obscure hints hidden deep within its code suggest a possible Israeli origin -- or an attempt to deceive investigators.
