Blockpass Data Breach Intelligence Report - March 2019

April 2019
Over the course of March, the Blockpass Research Team analyzed 7 data breach events, chosen either for their scale, significant impact on consumers, or their implication on a global scene. This month, the largest single data breach was in Digital Marketing; although, a number of health-related services were also affected. 

Never before has our analysis of cybersecurity breaches gotten closer to the ‘b’ word. On March 22nd, a cybersecurity researcher revealed that a digital marketing firm,, had leaked the personal information of the largest magnitude we have seen in our reports to date: just under one billion individuals. As a result, March turned out to be the worst month we’ve seen so far in terms of data security. Only taking into consideration the events that we analyzed, 13.1% of the world population was affected. This month stands as a testimony to the risk factor that is experienced when companies collect massive amounts of data for marketing purposes, and the lack of security we currently live with.

Blockpass' solution is this unsecured amassing of data. All Blockpass users are empowered to be in full control of their data. Only those companies that the user wants to approve have access to their data. Ultimately, Blockpass aims to put an end to huge leaks like the ones we have seen this month.
