It took me a while to figure that out, until I realized what was going on:

Port 135 probes are *SO* prevalent that *every single* submission to DShield
has at least one or two dozen (I know my laptop gets several an hour).  So what
that's *REALLY* measuring is "How many DShield sites have made any sort of
report that day" - the "number of targets" is approximately "number of sensors
active today".

Take a look at the "sources" line instead....
