Similar to Yee Ching's diary on Thursday, I noticed an oddity in the Dshield data last weekend (which I had hoped to discuss in a diary on Wednesday, but life got in the way) and thought it was worth asking around to see if anyone knows what is going on. As soon as I saw it, I reconfigured my honeypots to try to capture the traffic, but wasn't able to. I'm always very interested when I see some of the legacy ports and protocols pop up. In this case, %%port:37%% is the time protocol which operates on both TCP and UDP and is one of the many services that frequently ran on the low ports of Unix machines I administered back in the 1980s and 1990s. In recent years, most operating systems have disabled these services since they only seemed to be used for DDoS purposes. On Thursday, I took another look at the graph.
