America's water systems are getting hacked amid security gaps: 'No one guarding these systems'

TL;DR

  • U.S. public water systems are experiencing a surge in cyberattacks, highlighting security weaknesses.
  • The attacks primarily target internet-connected industrial computers called PLCs, which control essential water system functions.
  • PLCs often lack proper security, such as strong passwords or firewalls, making them vulnerable to hackers.
  • Attacks have been reported in at least a dozen states, with potential links to Iran-backed hackers.
  • While no attacks have affected drinking water quality, some have caused pressure loss and forced boil-water advisories.
  • Experts warn that hackers could cause more severe disruptions, potentially impacting hospitals and other critical infrastructure.
  • The lack of federal regulation means the full scale of the impact is unknown.
  • Consumers are advised to store water at home as a preparedness measure against potential disruptions.
