According to the U.S. Department of Homeland Security, "Ransomware is a type of malicious software, or malware, designed to deny access to a computer system or data until a ransom is paid. Ransomware typically spreads through phishing emails or by unknowingly visiting an infected website. Ransomware can be devastating to an individual or an organization."

Officials said the attack is affecting the town’s ability to service the public, and all city employees currently have limited functionality.

IT workers discovered a ransom demand in the virus, but it didn't specify an amount.

“(It) may have temporary impacts on service to the public, such as permits, public records requests, and business services. Town Departments are developing alternative solutions to continue serving Collierville residents; emergency services are operating as normal,” officials said in a release.
