WeFi 3.2.1.4.1 when diagnostic mode is enabled stores (1) WEP (2) WPA and (3) WPA2 access-point keys in (a) ClientWeFiLog.dat (b) ClientWeFiLog.bak and possibly (c) a certain .inf file under %PROGRAMFILES%\\WeFi\\Users\\ and uses cleartext for the ClientWeFiLog files which allows local users to obtain sensitive information by reading these files.
