HOWTO: Circumvent VADIS expiration date

[PiRX]

Hi all!

We all know, that one of most annoying things about VADIS is it's hard-coded (maybe not that hard-coded) expiration date.

Yesterday I got a bit fed-up with it (because of how annoying it is to make VirtualBox to NOT keep correct clock on guest system), and decided to do a bit of spelunking in VADIS.exe with Ghidra.

To my surprise it was simpler than I expected, because I found that VADIS has functionality to disable it through configuration setting in Windows registry (I guess for testing purpose or whatever).

So, here is a reg file for disabling it (used on 64 bit-windows 7 virtual machine)

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Volvo\VADIS\Bucket\ExpirationChecking]
"EnableExpirationCheck"="0"

For non-tech persons - just save it as something.reg file and double click on it.

I think that for 32-bit you just need to remove the "\Wow6432Node" part from it, but I haven't tested it.
