Several government agencies, including the FBI, the EPA and the Cybersecurity and Infrastructure Security Agency (CISA) — the agencies making sure sewage and other biohazards stay out of your drinking water — put out an advisory last week highlighting cyber threats to local water and wastewater systems.
