'We’re putting you all on notice': Behind the technology Trump could use to hack your phone

New HBO documentary Surveilled looks at the dangers of spyware like Pegasus , developed by Israeli firm NSO .

Director Matthew O'Neill and journalist Ronan Farrow discuss the influence of the Israeli military in the development of some of the most widely used versions of these surveillance technologies.

Farrow: "We're making and selling a weapon that is largely unregulated.” O’Neill: “We could all be caught up".

Ronan Farrow : The Biden administration, the executive branch, can do relatively little, as far as I understand, that can’t be undone by the Trump administration.

He says the selection of someone like Kash Patel , who would give Trump free rein to manipulate law enforcement investigations if he were running the FBI , has suggested that the executive should have absolute power.

Farrrow: Trump and his associates have explicitly threatened journalists with prosecution.

Matt O’Neill traveled the world with Ronan as he interviewed people almost on every continent.

O'Neill : "This is not a partisan issue. People who don’t want big government, people who have traditional conservative values should especially care about protecting people from this tech".
