Israel, on Thursday, established a commission to review its spyware software Pegasus, the head of parliament's Foreign Affairs and Defence Committee said. This development took place after Pegasus was implicated in possible mass surveillance of journalists, human rights defenders and 14 heads of state.

"The defence establishment appointed a review commission made up of a number of groups," lawmaker Ram Ben Barak told Army Radio.

"When they finish their review, we'll demand to see the results and assess whether we need to make corrections," the former deputy head of Israel's Mossad spy agency added.

Their phone numbers that were allegedly under surveillance were among some 50,000 potential targets on a list leaked to rights group Amnesty International and Paris-based Forbidden Stories.

NSO has said the leak is not a list of targets or potential targets of Pegasus. The technology firm's chief executive Shalev Hulio told Army Radio Thursday that he would "be very pleased if there were an investigation, so that we'd be able to clear our name".

He also alleged there was an effort "to smear all the Israeli cyber industry".

NSO has said it exports to 45 countries, with approval from the Israeli government.

Hulio said the company could not disclose the details of its contracts due to "issues of confidentiality," but said he would offer full transparency to any government seeking more details.

"Let any state entity come along -- any official from any state -- and I'll be prepared to open everything up to them, for them to enter, to dig around from top to bottom," he said.

Ben Barak said Israel's priority was "to review this whole matter of giving licences."

Pegasus had "exposed many terror cells", he said, but "if it was misused or sold to irresponsible bodies, this is something we need to check."

Paris-based Reporters Without Borders on Wednesday called for a moratorium on cyber-surveillance software.

Pegasus can hack into mobile phones without a user knowing, enabling clients to read every message, track a user's location and tap into the phone's camera and microphone.

High profile names like Indian political leader Rahul Gandhi, the closest circle of advisors around the Tibetan spiritual leader, the Dalai Lama, journalist Siddharth Varadarajan and the nephew of West Bengal's Chief Minister Mamata Banerjee, Abhishek Banerjee, are on the list of potential targets.
