Hacking remains the top breach type for number of incidents while the Internet has exposed the most records this year. By NAICS economic sector, medical services, retailers and public entities experienced the most breaches, but when all business related sectors are combined, general business remains the most breached organization type. 

In Q3 alone, six breaches exposed 100M or more records, accounting for 3.1 billion records exposed between July 1st and September 30th . Accounts vs People vs Records - Orvibo, the largest breach disclosed so far this year, is reported to have exposed approximately 2 billion records. It is worth noting the open dataset included approximately 2 billion entries that were associated with a much lower number of user accounts. The actual number of user accounts exposed in the breach is unknown but is likely to be around one million, as that is the number of customers claimed by Orvibo.

1. Healthcare - 343 
2. Retail - 307
3. Public Administration - 264
