We have recently began scanning for accessible MySQL server instances on port 3306/TCP. These are instances that respond to our MySQL connection request with a Server Greeting. Surprisingly to us, we found around 2.3M IPv4 addresses responding with such a greeting to our queries. Even more surprisingly, we found over 1.3M IPv6 devices responding as well (though mostly associated with a single AS). IPv4 and IPv6 scans together uncover 3.6M accessible MySQL servers worldwide.
Control of the internet is increasingly part of any modern conflict.
Disappointed with the lack of US response to the Hermit Kingdom's attacks against US security researchers, one hacker took matters into his own hands.
