Hackers with possible links to Iran appear to have breached an Israeli water reservoir, cybersecurity firm Otorio says. The HMI system did not require any authentication to access and modify the system. This allowed the attackers to tamper with the water pressure, change temperatures and more.

In May, Trend Micro released a report that HMI systems used in “smart factories” were susceptible to hacking.”]
