Last July, an absolutely devastating ransomware attack hit Saint Paul, Minnesota, causing one of the worst cybersecurity incidents in American municipal history.
The entire city’s computer systems were paralyzed, network communications failed, citizens couldn’t pay their water bills, libraries lost Wi-Fi access, and even city employees couldn’t work.

This turned out to be a ransomware attack orchestrated by a hacker group called “Interlock.”
What’s infuriating is that when the city refused to pay their demands, these criminals released 43GB of citizen data onto the internet..

Let’s examine exactly what happened and what we can learn from it.
