The malicious outsider attack on food delivery app Zomato that exposed 17 million records was the sixth biggest data breach globally in the first half of 2017, a new report said on Thursday.
According to the "Breach Level Index" released by digital security firm Gemalto, a total of 203.7 million data records were compromised in 18 data breaches in India in the first half.
