The Department of Homeland Security recently warned operators of critical infrastructure to protect industrial control systems that are connected to the Internet.
"DHS's Industrial Control Systems Cyber Emergency Response Team (ICS-CERT) reiterated a warning from last year that such systems can be detected by a new breed of Internet scanners such as Sh0dan [PDF file], citing an 'uptick in related activity' by researchers, and evidence that 'thousands' of ICS systems may be discoverable," writes Threatpost's Paul Roberts.
"ICS CERT is urging ICS asset owners and operators to audit the configuration of their systems and make sure they cannot be discovered using an Internet based scanning tool," Roberts writes.
