  MS-ISAC Identified SLTT Data Breach Attack Vector Yearly Breakdown  
The MS-ISAC identified 44 data breaches in Q1 2018. Comparatively, there were 58 data breaches in Q1 2017, a 31% decline attributed to a decrease in successful W-2 variant Business Email Compromise (BEC) scams. Reported data breaches increased 63% between Q4 2017 and Q1 2018. This increase is credited to the increased reporting of data exposed by third parties, which are entrusted with the data management of an SLTT government, the most prolific attack vector this quarter. Third party breaches account for 44% of breaches Q1 2018. The MS-ISAC recommends SLTTs work with their legal teams in order to create stringent data handling service agreements with third party contractors. Furthermore, the education sector remains the most impacted by reported data breaches, a trend that extends back to 2012.
