YanaComsecure 0 Posted June 21, 2023 Share Posted June 21, 2023 Hi all, Did someone try to use the recovery utility with virtual hyperV encrypted disk? Creating simple ISO file with the utility didnt work, it outputs the error : "The utility is executing from read only optical media In order to store log information USB storage will be required. Please connect USB storage to use for the logfile." Link to comment Share on other sites More sharing options...

Hi, Whilst using the ESET Recovery Utility in ISO Mode you will need to insert a FAT32 USB in order for it to be functional and create logs of the events that occurred in case anything goes wrong Its a requirement, because if anything failed without logs it would be difficult to determine what the issue is and this prevents that.

YanaComsecure 0 Posted June 21, 2023 Author Share Posted June 21, 2023 Hi Kieran, Understood, so it is more about trying to create a virtual storage device to be used in the boot.. It didnt work for me for now Link to comment Share on other sites More sharing options...
ESET Staff Kstainton 31 Posted June 21, 2023 ESET Staff Share Posted June 21, 2023 Hi @YanaComsecure, May I ask what the use case is here? Why are you encrypting a Hyper-V Workstation, what is the attack vector here? Are you simply testing attempting to decrypt the Hyper-V Workstation or are you in a situation that requires recovery? Just trying to understand, I am currently talking to the team about this, but would like to know what exactly is the requirement here Thank you, Kieran Link to comment Share on other sites More sharing options...
YanaComsecure 0 Posted June 22, 2023 Author Share Posted June 22, 2023 Hi Kieran, I encrypted the VM for a test, and now trying to do recovery data. If it is not supported I can try to use physical computer for this, it is for convenience for testing environment. Link to comment Share on other sites More sharing options...
ESET Staff Solution Kstainton 31 Posted June 22, 2023 ESET Staff Solution Share Posted June 22, 2023 HI @YanaComsecure, We use VMWare Workstation for Development/Testing successfully, VMWare allows you to connect a Physical USB, going by some research you cannot do this with Hyper-V which may be the cause of the issue here. As I cannot see that it allows USB to be bootable. Are you able to test on a physical computer and report back? Thank you, Kieran Link to comment Share on other sites More sharing options...
YanaComsecure 0 Posted June 22, 2023 Author Share Posted June 22, 2023 Hi Kieran, Thanks for checking, I will try to find a workaround using VMWARE env then, or using physical usb device. Thanks! Link to comment Share on other sites More sharing options...
