After Facebook data breach, Twitter data breach comes in open

London, May 01: After the massive Facebook data scandal, it has now come to notice that Twitter had also sold users' data to a Cambridge Analytica researcher who collected the data of nearly 87 million Facebook users without their knowledge and permission, The Sunday Telegraph reported.

According to the report, Twitter sold public data access "for one day" in 2015 to Aleksandr Kogan, then a psychology researcher with University of Cambridge, and his company Global Science Research (GSR).

"GSR paid for one day of access in 2015, Twitter said, and scooped up a 'random sample' of public tweets covering a period between December 2014 and April 2015. Twitter added that it 'did not find any access' to private information," the report noted.

Kogan reportedly said the Twitter data had only been used to create "brand reports" and "survey extender tools" and that he had not violated Twitter's policies.
