Interesting Shodan searches: Moxa ethernet->serial bridges

I’ve noticed, whilst sat on the train, an AP called “MOXA”. A quick google shows that these guys are in the “industrial IoT” market. I suspect they have something to do with the CCTV on the train.

Off to Shodan for a search, limited to port 80.

~90 devices come back, nearly all MiiNePort E2. Very few have authentication turned on, many that do are using default credentials.

Also, there appears to be a utility called NPort which is used for discovering devices. It wouldn’t be the first time that a discovery protocol has been the downfall of one of these bridges.
