Who is security-research.org ?

["John Levine" <johnl () iecc com>]

I noticed them in my DNS logs, trying to do AXFRs of random zones I host.  The probes
are coming from Hetzner, a low-cost German hosting provider with a history of tolerating
dodgy customer behavior.

Their website, which is hosted at Vultr, airly assures us it's nothing personal, they
scan everyone to make the Internet better, just filter us, but if you insist, you can
send objections to noc () m-d net.

Any idea who they are?  I expect it's more likely that they're self-important than
evil. but still, sigh.

R's,
