Cyber threats from Iran against water infrastructure in the United States are increasing and could represent a "silent war" that continues despite a potential military de-escalation between Tehran and Washington, writes The Washington Post. According to the report, the U.S. Cybersecurity and Infrastructure Security Agency recorded more than 1,900 attempts at cyber attacks on U.S. water systems in just one month, with Iran identified as the primary source. Although most of these attacks have failed, experts warn that they highlight serious vulnerabilities in the protection of critical infrastructure.
