Coldfusion CFIDE bitcoin mining exploit?

Just found the following 2 new directories on multiple windows server 2003 installations of coldfusion 9:

{wwwroot}/CFIDE/m32 3/13/2014

contains:
libcurl-4.dll
libwinpthread-1.dll
m32.exe
zlib1.dll

and

{wwwroot}/CFIDE/m64 3/17/2014

contains:
libcurl-4.dll
libwinpthread-1.dll
m64.exe
zlib1.dll

When running m32.exe it appears that it’s some type of wrapper for a bitcoin mining operation:

I cannot find any information about this and have no idea how these files got on the servers – we were cryptojacked. For now I’m relocating them for further investigation as the processes were being launched through Jrun…
