US cyber attacks on Iranian targets not successful: Minister

U.S. cyber attacks against Iranian targets have not been successful, Iran's telecoms minister said on Monday, within days of reports that the Pentagon had launched a long-planned cyber attack to disable his country's rocket launch systems.

Tension runs high between longtime foes Iran and the United States after U.S. President Donald Trump on Friday said he called off a military strike to retaliate for the Middle East nation's downing of an unmanned U.S. drone.

U.S. President Donald Trump said on Saturday he would impose fresh sanctions on Iran but that he wanted to make a deal to bolster its flagging economy, an apparent move to defuse tensions following the shooting down of an unmanned U.S. drone this week.

On Thursday, however, the Pentagon launched a long-planned cyber attack, Yahoo News said, citing former intelligence officials. The cyber strike disabled Iranian rocket launch systems, the Washington Post said on Saturday.

"They try hard, but have not carried out a successful attack," Mohammad Javad Azari Jahromi, Iran's minister for information and communications technology, said on social network Twitter.

"Media asked if the claimed cyber attacks against Iran are true," he said. "Last year we neutralised 33 million attacks with the (national) firewall."

Azari Jahromi called attacks on Iranian computer networks "cyber-terrorism", referring to Stuxnet, the first publicly known example of a virus used to attack industrial machinery, which targeted Iran's nuclear facilities in November 2007.

Stuxnet, widely believed to have been developed by the United States and Israel, was discovered in 2010 after it was used to attack a uranium enrichment facility in the Iranian city of Natanz.

Washington accused Tehran of stepping up cyber attacks.

Officials have detected a rise in "malicious cyber activity" directed at the United States by people tied to the Iranian government, Chris Krebs, director of the Department of Homeland Security's cybersecurity agency, said on Saturday on Twitter.

#BatchWiper, a new data-wiping virus targets Iranian computers

Recently, The Iranian CERT reported that a new piece of malware targets Iranian computers that capable of wiping the files from the infected computers.

SophosLabs have analyzed the new sample and confirmed that the malware attempt to erase the contents of any files on D, E, F, G, H and I drives.

The malware is distributed as a self-extracting WinRAR archive called GrooveMonitor.exe that drops three executable files: juboot.exe, jucheck.exe and SLEEP.EXE.

The 'justboot.exe' is a DOS BAT file that has been converted to PE format that uses 'SLEEP.exe' to wait for few seconds before it adds a registry entry that ensures that 'jucheck.exe' is executed each time the computer restarted.

The primary function of the malware is wiping the files from hard drive, but it does so only within few specific date ranges, each about two days long.

After deleting the data , the malware runs chkdsk in order to trick the victim into believing that the files have been corrupted because of software or hardware failure.
