Gemalto released the latest findings of the Breach Level Index, a global database of public data breaches, revealing 945 data breaches led to 4.5 billion data records being compromised worldwide in the first half of 2018.

Compared to the same period in 2017, the number of lost, stolen or compromised records increased by a staggering 133 percent, though the total number of breaches slightly decreased over the same period, signaling an increase in the severity of each incident.

A total of six social media breaches, including the Cambridge Analytica-Facebook incident, accounted for over 56 percent of total records compromised. Of the 945 data breaches, 189 (20 percent of all breaches) had an unknown or unaccounted number of compromised data records.
