The FBI has opened an investigation into a cyberattack targeting a supplier to the United States water sector, Reuters reported exclusively, as federal authorities grow increasingly alarmed about Iran-linked hacking operations aimed at critical American infrastructure. The breach represents a fresh escalation in a pattern of adversarial cyber intrusions focused on systems that underpin everyday life for millions of Americans.

An attack on a supplier — rather than a utility directly — underscores how threat actors are pivoting to supply-chain vectors to maximize reach and disruption potential.
