There was the infamous March ransomware attack in Atlanta during which SamSam malware hoodwinked municipal corporations. The attack is considered the worst attack in US history. Out of 424 software programs implemented by the city, more than one-third was made offline or partly crippled when the incident occurred. Hackers had demanded $51000 worth of Bitcoin in exchange for the release of encoded city data.

The Durham County government in North Carolina implemented a multilayered procedure which included Cisco Umbrella, firewalls from Palo Alto Networks and cloud-based security services provided by Dell SecureWorks. Umbrella is used to analyze the domain-name-system-requests (DNS), and if it locates a malicious site, the software is programmed to automatically block the particular webpage long before it strikes the firewall. The network’s firewall and vulnerability detection capabilities will continue to observe potential malware and malicious websites, at times when DNS request eludes Umbrella.
