Take Back Wednesday? SQL Slammer... still alive but barely kicking

Got a couple of reports recently about an increase in port 1434 scanning for the infamous "Slammer" (aka "Saphire") MS-SQL Server vulnerability. Sad to say: It looks like it never went away... There appears to be still a "background" of about 50 source IPs/day that scan for port 1434. Now this is way down from the numbers we had in 2003/2004 (20-30,000 sources per day). But to put it in perspective: This was still about an order of magnitude lower than what we see for Mirai now. So let's look at this again in 13 years, and see how many DVRs are still sending Mirai style scans. Just like with Slammer, all it takes is a couple of them to survive to immediately infect new systems as they come online.
If you want a list of yesterday's sources, check here: https://isc.sans.edu/dailysources.html?mintargetport=1434&maxtargetport=1434
After removing some of the research scanners (Shodan, Shadowserver, Quadmetrics), I am left with this list:

No idea if these are actually infected systems, or if these systems are just scanning for various "research projects" as well. Right now, none of the systems appears up.
