No successful cyber attack carried out by US, says Iran

Iran said on Monday said that no cyber attack against the Islamic republic has ever succeeded. The statement came after media reported that the US launched cyber attack last week amid a standoff between the two countries.

Taking to Twitter, telecommunications minister Mohammad Javad Azarari Jahromi without referring to any US attack said “The media are asking about the veracity of the alleged cyber attack against Iran. No successful attack has been carried out by them, although they are making a lot of effort.”

US President Donald Trump disclosed last week that he called off a US military strike on Iran at the last minute, saying it would be a disproportionate response to Thursday's downing of a high-flying, unmanned US aircraft over the Strait of Hormuz.

“But after the drone’s downing, Trump secretly authorised US Cyber Command to carry out a retaliatory cyber attack on Iran,” The Washington Post reported. The report said the strikes, which caused no casualties, had been planned for weeks and were first proposed as a response to the tanker attacks.

The attack crippled computers used to control rocket and missile launches, according to the Post, which cited people familiar with the matter. Yahoo cited two former intelligence officials as saying the US targeted a spying group responsible for tracking ships in the strategic Strait of Hormuz, where Washington has blamed Iran for two recent mine attacks on oil tankers.

Iran on Saturday warned the United States that any aggression will result in serious consequences for the interests of Washington and its allies in the Middle East region. "Firing one bullet towards Iran will set fire to the interests of America and its allies" Tasnim news agency quoted armed forces general staff spokesman Brigadier General Abolfazl Shekarchi.

He said,"Today, the situation in the region is to Iran's advantage. If the enemy -- especially America and its allies in the region -- make the military mistake of shooting the powder keg on which America's interests lie, the region will be set on fire."

 While Iran said that the downed US Global Hawk spy drone entered its territorial waters, the Pentagon claimed it was above international waters when it was hit by the  Iranian Revolutionary Guard. According to Iranian state TV, "the US-made Global Hawk surveillance drone was brought down by its Air Force" in the country's southern coastal province of Hormozgan.

The downing of the drone -- which Tehran insists violated its airspace, a claim Washington denies -- has seen tensions between the two countries spike after a series of attacks on oil tankers near the strategic Strait of Hormuz.
