The number of IoT devices and SCADA systems connected to the Network without appropriate security measures continues to increase, making critical devices vulnerable to potential attacks and hacking attempts. A&O IT Group researchers reported that despite a number of high-profile attacks on SCADA systems, most devices and protocols do not have reliable protection.
the increase in the number of unprotected devices, experts believe, may be a consequence of providing access to systems to remote employees due to the coronavirus pandemic (covid-19). the results of shodan search queries revealed 43,546 unprotected devices: tridium (15,706), bacnet (12,648), ethernet ip (7,237), modbus (5,958), s7 (1,480) and dnp (517).
According to experts, the most vulnerable devices are located in the United States — 25,523. Of the six groups analyzed, the smallest number of S7 devices were detected in the United States, but many of them are Conpot hanipots, which indicates a higher level of vigilance of local information security experts. Other countries topping the list for the number of unprotected devices include Canada, as well as Spain, Germany, France and the United Kingdom.
"Critical infrastructure runs on legacy networks that were previously isolated from the IT network. There is a growing demand for connectivity and the ability to work remotely, resulting in legacy networks that are often more than 25 years old. As a result, the infrastructure that manages global operations is vulnerable and contains a number of cybersecurity problems," the researchers explained.
