Using CPAU to execute scripts as Administrator hiding credentials

Ocasionally we need to execute orders or scripts as Administrator, and “runas” is not a valid option because users can read the script and find a super user password (No way). In this cases we can try with CPAU, with this free tool we can generate an scripted job that can be called from script secure. The job contains de execution command and the dessired credentials. Let’s prepare an example.

First of all we need to download CPAN.zip from it’s webpage http://www.joeware.net/freetools/tools/cpau/ after decompressing we wil get a CPAN.exe ready to use.

In this simple exercice que show how we can create an encrypted job and the then execute.

Step 1 Generate a job

Example:

This command will generate an encrypted file named registerSome.job, we can try to read this file en we will see some thing like this:
