Version 1.3 is now available. I implemented a wise suggestion from Les ... to do with the tokenized (encrypted) file. The token file is now a "moving target" - the encryption will vary between invocations - even if the command line remains constant. This will hinder any "brute force" attempt to crack the encryption.

Okay, RUNNAS should now be up to version 1.6

Been chatting with Shawn on MSN and ironed out a few other issues with error codes.

Shawn should post and update soon.

Runnas 1.5 is available. Added the /CRC switch. This performs an optional Cyclic Redundancy Check on the command line executable and saves it to the tokenfile. Later, when run from a tokenfile, the CRC is re-validated for added security.

Sounds great so far.

Can you turn it into a COM component and tokenize the "cmd files"?

runnas 1.6 is available. added the following two parameters:

/allowargs - allow additional arguments to be passed to tokenfile.

/args - additional arguments for tokenfile.

args huh?
caveat emptor
I could see that possibly be exploited in some cases.

yup i agree - thats why by default its turned off. but otherwise pretty handy to have. would definitely by a security issue if your were running cmd.exe.

ja, I'm sure you are aware of the implications. Just wanted to put on record that when it comes to security, it is caveat emptor.

Be careful there Shawn. Don't want your util turning out to be like the SONY software. They certainly did not forsee or wish for it to be abused as such but you can see the outcome there.

Anyways... KF.ORG appears to be down at the moment, can't download the latest version at the moment.

ja understood. like i say by default its not enabled. so one has to enable it in a heads-up kinda fashion. much would depend on what was being called and how. but you guys do make a good point.

ok its been re-hosted.

Since there are times when an application must be installed under the current user's context would it be possible to add a /RUNASADMIN switch that either temporarily raises the user's rights or allows that process to run elevated?

Chris, it already should work for many things as the main process can be launched using the current user's profile, but with the credentials of an Administrative account.

If a stub process is kicked off that did not maintain the thread process level then it would lose those Admin rights, but otherwise should run as the account you specified.

I'm sure that there are installs that can or would be problematic, but would think many others should work fine as the process is then editing the registry and placing files in the system32 folder, etc...

I plan on doing some testing in that area this week and will post my findings.
