Safe Run As - Keylogger Protection
------------------------------------------------------------------------
SUMMARY
DETAILS
This tool is created to protect administrative passwords against
keyloggers. Administrators passwords are stored in the AES encrypted file
on the removalable storage (flash-drive, floppy). Then, when you need to
use 'run as' command you launch saferunas.hta, and provide username and
encryption key.
Password are decrypted and cmd.exe is launched with selected user's
privileges. Edit.hta tool can be used to create and modify file with
encrypted passwords.
Attention:
1.This tool doesn't protect against smart malware which can copy password
file and steal encryption key.
2.You cant choose program to run. Coming soon.
3.In this version password entered is used as AES key directly. This is
bad idea. PKCS#5 version is coming soon.
4.Attention when you run GUI application as high privileged user, you are
vulnerable for Shatter-style attacks (see shatter vbs for example).
