The healthcare sector was hit by 37 data breaches in September, causing about 250,000 patient records to be compromised. That was a far cry from the 8.8 million records breached in August, however.

Still, the September figure is part of a trend that has seen the number of data breaches increasing each month in 2016, according to the Protenus September Breach Barometer.

Insider threats and hacking were the two biggest causes of data breaches. The former was responsible for 41%, or 15 incidents, whereas the latter accounted for 32%, or 12 incidents. Seven of the insider threat cases were accidental in nature, with the remaining eight being attributed to purposeful wrongdoing.
