Russian cyber security company Kaspersky said on Wednesday hackers used a computer virus to breach the nuclear talks which the West was having with Tehran to curb Iran’s nuclear programme.
The company said it found the virus in three European hotels used in negotiations and in Kaspersky’s own computers.
According to both Kaspersky and US cyber company Symantec, the virus has some similar programming with Duqu virus, an espionage software that security experts believe to have been developed by Israelis.
"Most notably, some of the new 2014-2015 infections are linked to the P5+1 events and venues related to the negotiations with Iran about a nuclear deal," said the Kaspersky statement.
It also said the virus has very complex structure that could only be made by sponsorships of a state.
The United States in mid-February limited the quality and depth of the intelligence and information it shares with Israel about the ongoing progress of nuclear talks with Iran, accusing Israel of using selective leaks to distort the US position.
US President Barack Obama wants to reach an agreement with Iran over its nuclear programme, while Israel’s Benjamin Netanyahu has been doing everything he can do to block the talks.
Israel has been saying a possible agreement is a bad deal and would put Israel in danger, denouncing the diplomatic opening to Iran.
Russian Kaspersky said the new software, what they call Stuxnet, had unknown type of control commands which have been used at the European hotels during the nuclear talks.
