After a fierce debate among Israeli officials, Israel’s Ministry of Defense blocked Estonia from using the spyware on any Russian mobile numbers worldwide. The following year, however, a senior Russian defense official contacted Israel security agencies to notify them that Russia had learned of Estonia’s plans to use Pegasus against Russia.

The Estonian government made a large down payment on the $30 million it had pledged for the system. In the Estonian case, negotiations to purchase Pegasus began in 2018, and Israel at first authorized Estonia to have the system, apparently unaware that Estonia planned to use the system to attack Russian phones. Ukrainian officials have sought Israeli defense equipment to counter the Russian threat, but Israel has imposed a near-total embargo on selling weapons, including Pegasus, to Ukraine. Since the Russian invasion of Crimea in 2014, the country has increasingly seen itself as a direct target of Russian aggression and espionage.

In the case of Ukraine, the requests for Pegasus go back several years.

It can also turn the mobile phone into a tracking and secret recording device, allowing the phone to spy on its owner. Pegasus is a so-called zero-click hacking tool, meaning that it can stealthily and remotely extract everything from a target’s mobile phone, including photos, contacts, messages and video recordings, without the user having to click on a phishing link to give Pegasus remote access.
