"The nuclear negotiations has enemies, specially the Zionist regime that does not want the talks to succeed. Owing to the same fact, they would spare no efforts and their spying was and is not an unexpected issue," Reza Najafi said on Friday.
Yet, the IAEA envoy stressed that the negotiators have always adopted the necessary precautions.
A cybersecurity firm has identified breaches in its software at three luxury Swiss hotels from a virus considered a hallmark of Israeli intelligence operations. The three hotels hosted the Iran nuclear talks.
Kaspersky Lab ZAO discovered the virus at the three hotels where world powers and Iran held negotiations over its nuclear program in the past year, the Wall Street Journal reported on Wednesday.
According to its report of the investigation, Kaspersky crosschecked thousands of hotels in search of similar breaches and found only three. The firm declined to name the hotels, but the negotiations have been held in just six hotels in Switzerland and Austria since the diplomatic effort first began.
Kaspersky has concluded that the perpetrator was a sophisticated virus known as Duqu, which allows its handlers to monitor activity, steal computer, files and eavesdrop on the rooms in which computers are operating.
