Industrial cybersecurity firm Otorio reported in early September that a pro-Palestine hacktivist group named GhostSec had claimed that it ‘hacked’ 55 Berghof programmable logic controllers (PLCs) located in Israel. The hackers published a video showing that they had access to the PLC’s administration panel and an associated human-machine interface (HMI). They also posted a screenshot showing that a PLC had been stopped, which, for someone who doesn’t know much about how industrial processes work, might indicate that significant disruption may have been caused.
