In recent months, an increased number of ransomware attacks have occurred against U.S critical infrastructure, including targeted attacks against the water sector. Ransomware as defined by DHS’s Cybersecurity & Infrastructure Security Agency (CISA) is “an ever-evolving form of malware designed to encrypt files on a device, rendering any files and the systems that rely on them unusable.” Cybercriminals and state actors will leverage this technique to block access to these resources or threaten to publish any private or protected information to the public unless a ransom is paid.

To get to the bottom-line, our ask is as follows:

• For Water utilities: Please follow the steps outlined in memo to protect your organization from ransomware attacks. Additionally, if you suspect that you organization is the victim of a ransomware attack please contact CISA (central@cisa.dhs.gov) or local law enforcement.
