I&#;x26;#;39;ve been working on comparing data from different DShield [1] honeypots to understand differences when the honeypots reside on different networks. One point of comparison is malware submitted to the honeypots. During a review of the summarized data, I noticed that one honeypot was an outlier in terms of malware captured.

It has been nearly three years since we last looked at the number of industrial devices (or, rather, devices that communicate with common OT protocols, such as Modbus/TCP, BACnet, etc.) that are accessible from the internet[1].
