VIENNA - Malicious software infected some UN nuclear agency computers over the past few months but no data in its network has been compromised, the agency said on Tuesday.
The International Atomic Energy Agency (IAEA) plays a central role in global efforts to prevent the spread of nuclear weapons. Among other politically sensitive tasks, it is investigating Iran's disputed nuclear activities.
Late last year, anti-Israeli hackers posted data online stolen from one of the IAEA's servers but the UN agency said no sensitive information regarding its nuclear inspections had been affected.
On Tuesday, the IAEA said some computers operated by the agency had been infected by malware during the past several months, without giving details on the possible origin.
The computers were located in common areas of the agency's headquarters in the Austrian capital, known as the Vienna International Centre (VIC), where IAEA staff as well as member state officials work and meet.
The most worrying attack, experts said, were those on Saudi oil firm Aramco - effectively destroying tens of thousands of computers - and Qatari gas export facilities. Saudi Arabia and Qatar are both regional allies of the West.
