In this challenge we get an ova file that has been infected by the ransomware Petya. The bootloader has been overwritten
and when booting it the master file table will be encrypted. Our goal is to safe the data and find the flag. We also
know that the OS is encrypted with the password IWillNeverGetAVirus.
With tar-xvf HACKvent_thx_awesome_1n1k.ova we extract the vmdk file and then we mount it. Then we have to decrypt the
volume using cryptsetup. Now we can access the files and get the flag.
