WASHINGTON - Wikileaks will provide technology companies with exclusive access to CIA hacking tools that it possesses so they can patch software flaws, founder Julian Assange said on Thursday, presenting Silicon Valley with a potential dilemma.

If the offer is legitimate, it would place technology companies in the unusual position of relying on Assange, a man believed by some US officials and lawmakers to be a pawn of Russian President Vladimir Putin, to share cyber vulnerabilities stockpiled by a secretive US spy agency.

It was not clear how WikiLeaks intended to cooperate with the companies. The group published documents on Tuesday describing secret Central Intelligence Agency hacking tools and snippets of computer code. It did not publish the full programs that would be needed to actually conduct cyber exploits against phones, computers and Internet-connected televisions.

"Considering what we think is the best way to proceed and hearing these calls from some of the manufacturers, we have decided to work with them to give them some exclusive access to the additional technical details that we have so that the fixes can be developed and pushed out, so people can be secure," Assange said during an online press conference from the Ecuadorean embassy in London.

Assange took refuge at the embassy in 2012 to avoid extradition to Sweden over allegations of rape, which he denies.

Microsoft Corp and Cisco Systems Inc, whose wares are subject to attacks described in the documents, said in response to Assange that they welcomed submissions of any vulnerabilities through normal reporting channels.

"We've seen Julian Assange's statement and have not yet been contacted," a Microsoft representative said. "Our preferred method for anyone with knowledge of security issues, including the CIA or Wikileaks, is to submit details to us at secure@microsoft.com so we can review information and take any necessary steps to protect customers."

Representatives of Alphabet Inc's Google, Apple Inc, Samsung Electronics Co Ltd and Huawei, whose products were also featured in the CIA catalog, did not answer requests for comment.

Responding to Assange, CIA spokesman Jonathan Liu, said in a statement: "As we've said previously, Julian Assange is not exactly a bastion of truth and integrity. Despite the efforts of Assange and his ilk, CIA continues to aggressively collect foreign intelligence overseas to protect America from terrorists, hostile nation states and other adversaries."

WikiLeaks' disclosures this week caused alarm in the technology world and among consumers.

One file described a program known as Weeping Angel that purportedly could take over a Samsung smart television, making it appear it was off when in fact it was recording conversations in the room.
