Hacking in the

public service sector

Hackers are targeting school districts and municipalities with powerful ransomware that locks and encrypts computer files. These groups make attractive targets because of the large number of employees with access to computers that are linked to vital systems.

Below are examples of online attacks that have occurred in the public service sector just in the past year:

  • Columbia Falls - $150k in bitcoin demanded to prevent the fraudster from publishing stolen school records

  • San Diego Unified School - Over 500k students and staffs’ personal data was stolen

  • Atlanta - Computer operations halted at the potential cost of $17 million

  • Ottawa, Canada - $100k was transferred by the city’s treasurer to a fraudster who masqueraded as the city manager
