Facebook pays millions of dollars every year to researchers and bug hunters to stamp out security holes in its products and infrastructure, but following Cambridge Analytica scandal, the company today launched a bounty program to reward users for reporting "data abuse" on its platform. The move comes as Facebook CEO Mark Zuckerberg prepares to testify before Congress this week amid scrutiny over the data sharing controversy surrounding Cambridge Analytica, a political consultancy firm that obtained and misused data on potentially 87 million of its users. Through its new "Data Abuse Bounty" program, Facebook would ask users to help the social media giant find app developers misusing data, Facebook announced Tuesday. Similar to its existing bug bounty program, the Data Abuse Bounty program will reward a sum of money to anyone who reports valid events of data collection that violate Facebook's revamped data policies. "This program is complementary to our existing bug bounty program in that it'follows the data' even if the root cause isn't a security flaw in Facebook's code," the company explains.
