Companies that supply water across the USA are on red alert for a potential cyberattack. According to Jeh Charles Johnson, former US Secretary of Homeland Security, all companies should make preventing attacks their first priority – especially those that supply vital goods. Johnson cited the example of the Colonial Pipeline attack in May 2021. The hack caused widespread panic and confusion, and left millions on the east coast of the USA without fuel. Johnson warned that such far-reaching consequences make an exciting target for hackers, who may look to encourage ransom payments by causing as much damage as possible.
