Security: Python script prints chrome usernames and passwords that are stored

VULNERABILITY DETAILS:These days I found a very beautifull python script that just prints the google chrome usernames and passwords that are stored on your machine.

In simple terms the script is self explanatory and goes to:


-"%APPDATA%\..\Local\Google\Chrome\User Data\Default\Login Data"
where the passwords and usernames are stored
-decrypt them
-and prints the list of usernames and passwords

Step 1
My Remote Function
Of course I couldn't resist to modify this script and to add a function that takes the list, stores It to a txt file and send It via gmail wherever I want to.

So If anyone on any machine clicks this script(exe) then all his google chrome credentials will be sent to a gmail account.

Yes, a user may steal their own passwords. No, a user should not run malware.
https://chromium.googlesource.com/chromium/src/+/master/docs/security/faq.md#Why-arent-physically_local-attacks-in-Chromes-threat-model

As Microsoft says in https://technet.microsoft.com/en-us/library/hh278941.aspx:

Law #1: If a bad guy can persuade you to run his program on your computer, it's not solely your computer anymore.
Law #2: If a bad guy can alter the operating system on your computer, it's not your computer anymore.
Law #3: If a bad guy has unrestricted physical access to your computer, it's not your computer anymore.

These facts are why local attacks are outside the scope of browser threat models.
