Over the December holidays, one of our researchers discovered proof of a much-theorized but we believe never before seen in the wild security breach.

Specifically, as the this researcher was analyzing email-borne threats (something they do on an ongoing basis), they observed that in a recent attack campaign, more than 25 percent of the malicious email (over 750,000 messages) came from things that were not conventional laptop or desktop computers, but rather members of the Internet of Things (IoT); a “Thingbot”-net*, as it were.

A more detailed examination suggested that there was a significant percentage of attack mail coming from other non-traditional sources, such as connected multi-media centers, televisions and at least one refrigerator.
