Johannesburg: The United Nations atomic agency has said some of its computers were infected by malicious software.
This is the second embarrassing IT slip-up over the past year for the International Atomic Energy Agency.
The IAEA, which holds highly sensitive information on its member states` nuclear facilities, said that none of its data was compromised.
According to the report, the agency said that the malware hit data on the USB drives of visitors to the IAEA in Vienna, although the devices themselves were not infected and did not spread the bug further.
Last November, the IAEA revealed that hackers had accessed one of its computer servers and posted the contact details of some of the watchdog`s experts online, the report added.
