Is Internet Accessible ICS A Problem?
• To critical infrastructure and society in general?
– In the US, no
– In other countries, some yes and some no
• Hydroelectric Dam in France
– In Japan, needs further investigation, but likely no
• To individual companies
– Yes, clearly YES
– In the US, in Japan and everywhere in the world
– Insecure by design ICS connected to the Internet can
be exploited. Only limit is the input/output.

Scanning the Internet for ICS
• You can use or build your own scanner
– Example: Project Redpoint discussed yesterday
• You can use a search engine for Internet
connected devices … Shodan

Searching Banners
• Many ICS devices have web, ftp, ssh, snmp and
other IT protocols that Shodan searches
• Create a search string and find devices

8.
Combining Search Techniques
• EtherNet/IP search identified a device in Japan
– But no useful information came back
• A secondary search of the IP address found an
FTP server and banner
– It’s a Yokogawa device, Data Management Device for
a paperless recorder
• The FTP server allowed anonymous FTP
– PERL Data Language file (PDL)
– Data Display File (DAD)

9.
Further Analysis
• PDL files has names/email addresses
– Belongs to major energy and mining company
– Could use these emails in spear-phishing attack
• Tags / Points
– ST1,沈砂池川側水位
– ST2,沈砂池山側水位
– ST3,三号開渠水位
– ST4,川側ﾚｰｷ電流

Let’s Find Some CC-Link
• CC-Link originally developed by Mitsubishi and is
widely deployed in Japan
– Now a standard run by the CC-Link Partner Association
• CC-Link IE does not use IP (or even Ethernet)
• So you can’t use Shodan to search directly for it

Maybe There Is A CC-Link Gateway
Anybus

What Should You Do?
• Asset Owners
– Search Shodan for your IP address space
• Vendors
– Search Shodan for your products
– A nice service for your customer
• Industry Group(s) / CERTS / Others
– Find ICS assets on the Internet and notify owners
