The police welcomed Monday's findings, saying they proved that “no deliberate activity was carried out in violation of the law.”
“Serious allegations against the conduct of the police turned out to be wrong, but unfortunately they caused great damage to the public’s trust in the police,” a police statement said.
Pegasus is a powerful tool that allows its operator to infiltrate a target’s phone and sweep up its contents, including messages, photos, contacts and location history — without the target being aware or taking any action.
NSO has been linked to snooping on human rights activists, journalists and politicians in several countries. In November, the U.S. blacklisted the company, saying its tools had been used to "conduct transnational repression."
NSO says it sells the product only to government entities to fight crime and terrorism, with all sales regulated by the Israeli government. The company does not identify its clients and says it has no knowledge of who is targeted. Although it says it has safeguards in place to prevent abuse, it says it ultimately does not control how its clients use the software.
The Association for Civil Rights in Israel said the latest findings show “major failures” that raise concerns about privacy and the rights of suspects. It called on authorities to bar police from employing such technology until detailed legislation is implemented to govern its use.
