WikiLeaks founder Julian Assange has said he will work with technology companies to help defend them against CIA hacking tools outlined in the organisation’s latest leak.
He said WikiLeaks would publish more confidential documents on the spy agency once a "key attack code" has been disarmed.
Speaking at an online press conference from the Ecuadorian Embassy in London, he said: "We have decided to work with them, to give them some exclusive access to some of the technical details we have."
He said some of the firms have already put counter measures in place, but others want more information.
The whistleblowing organisation, which previously refrained from publishing details of the US spy agency’s covert hacking programme, began posting a leak of CIA secrets on Tuesday.
"WikiLeaks has a lot more information on what has been going on with the cyber weapons programme," he said.
It is understood former Ukip leader Nigel Farage spent over half-an-hour inside the embassy just before the press conference started.
Samsung has said it is "urgently" investigating claims from WikiLeaks that intelligence agencies have used the firm's smart TVs as part of tools to spy on users.
The whistle-blowing website published thousands of documents it claims reveal the various hacking tools used by the CIA in the US, including techniques which target various consumer software including Windows, Google's Android and Apple's iOS.
WikiLeaks said software was developed to turn Samsung smart TVs into listening devices, a project codenamed Weeping Angel which the report claims also included input from the UK's MI5.
Mr Assange has been living inside the embassy for more than four years after being granted political asylum by the Ecuador government.
He is wanted for questioning in Sweden over a sex allegation, which he denies, but faces extradition to the United States if he leaves the embassy.
