The Massachusetts Attorney General Maura Healey announced that the state would be launching an investigation. The Democratic senator Mark Warner said the harvesting of data on such a vast scale for political targeting underlined the need for Congress to improve controls.
He has proposed an Honest Ads Act to regulate online political advertising the same way as television, radio and print. It may be data about people who are on Facebook that they have gathered themselves, but it is not data that we have provided. It includes emails, invoices, contracts and bank transfers that reveal more than 50 million profiles — mostly belonging to registered US voters — were harvested from the site in one of the largest-ever breaches of Facebook data.
Facebook on Friday said that it was also suspending Wylie from accessing the platform while it carried out its investigation, despite his role as a whistleblower. At the time of the data breach, Wylie was a Cambridge Analytica employee, but Facebook described him as working for Eunoia Technologies, a firm he set up on his own after leaving his former employer in late Cambridge Analytica interactive That legal letter was sent several months after the Guardian first reported the breach and days before it was officially announced that Bannon was taking over as campaign manager for Trump and bringing Cambridge Analytica with him.
Facebook did not pursue a response when the letter initially went unanswered for weeks because Wylie was travelling, nor did it follow up with forensic checks on his computers or storage, he said.
They waited two years and did absolutely nothing to check that the data was deleted. All they asked me to do was tick a box on a form and post it back. And built models to exploit that and target their inner demons Christopher Wylie A majority of American states have laws requiring notification in some cases of data breach, including California, where Facebook is based. Facebook denies that the harvesting of tens of millions of profiles by GSR and Cambridge Analytica was a data breach.
Facebook said it removed the app in and required certification from everyone with copies that the data had been destroyed, although the letter to Wylie did not arrive until the second half of The company is now investigating reports that not all data had been deleted. Kogan, who has previously unreported links to a Russian university and took Russian grants for research, had a licence from Facebook to collect profile data, but it was for research purposes only.
Quick guide Show Hide In December , while researching the US presidential election, Carole Cadwalladr came across data analytics company Cambridge Analytica, whose secretive manner and chequered track record belied its bland, academic-sounding name.
She found the first indications that Cambridge Analytica might have used data processing methods that breached the Data Protection Act. While chasing the details and ramifications of complex manipulation of both data and funding law, Cadwalladr came under increasing attacks, both online and professionally, from key players. But the growing profile of her reports also gave whistleblowers confidence that they could trust her to not only understand their stories, but retell them clearly for a wide audience.
Her network of sources and contacts grew to include not only former employees who regretted their work but academics, lawyers and others concerned about the impact on democracy of tactics employed by Cambridge Analytica and associates. Investigations in the UK remain live. Thank you for your feedback. The Observer has seen a contract dated 4 June , which confirms SCL, an affiliate of Cambridge Analytica, entered into a commercial arrangement with GSR, entirely premised on harvesting and processing Facebook data.
It then used the test results and Facebook data to build an algorithm that could analyse individual Facebook profiles and determine personality traits linked to voting behaviour. The algorithm and database together made a powerful political tool.
It allowed a campaign to identify possible swing voters and craft messages more likely to resonate. Key players At the time, more than 50 million profiles represented around a third of active North American Facebook users, and nearly a quarter of potential US voters. They did some research for us back in That research proved to be fruitless and so the answer is no. Cambridge Analytica also said none of the data was used in the presidential election.
