I don't know, but the same problem has been reported on Stackoverflow:
https://stackoverflow.com/q/46617329/6464308

If your queries look similar, then you might indeed be the victim of an attack.

Figure out where the function and the executable come from.

In case of doubt, disconnect the server from the network.
