Google says Android and Chrome systems ’protected’ amid WikiLeaks disclosures

US tech giant Google sought to reassure users of Android-powered phones and its Chrome operating system that it has already protected them from many of the security weaknesses disclosed by the anti-secrecy site WikiLeaks.

The news came about 36 hours after WikiLeaks released thousands of documents that it claims show a broad programme by the CIA to turn everyday gadgets such as iPhones into snooping tools by exploiting previously undisclosed software flaws.
