Hackers with possible links to Iran appear to have breached an Israeli water reservoir system. The HMI system lacked security protocols and did not require any authentication to access and modify the system. This allowed the threat actors to tamper with the water pressure, change temperatures and more. The U.S. Cybersecurity and Infrastructure Security Agency warned that Iran-based hackers are continuously improving their offensive cyber capabilities. In May, Trend Micro released a report that HMI systems used in “smart factories” were susceptible to hacking.”]
