unknown files
 

These files appeared in my home directory one day, and I have no idea how they got there, or where they are from. Can anyone tell me? My guess is that it is a automatic backup of some sort, but of what?

untitled1_MAS.bak
untitled2_MAS.bak
untitled3_MAS.bak
untitled4_MAS.bak
untitled5_MAS.bak

The file command says that each of them are XML files. The files will not open in Firefox. When I open them up in a text editor, It shows a bunch of random looking characters, so it might be something encrypted.

I can't tell you what the files mean. But I may be able to tell you how to find what is generating them.

From the command line, as root, run this command: find / -type f | grep 'MAS.bak'. Find should list the files you now have, and the file/script that is generating those file names.
