Technical Analysis
A special request to the Fortra Globalscape admin service returns what they call a TER – Trial Extension Request – which is a lightly-obfuscated Base64 string that contains the SHA256 sum of the harddrive’s serial number. The search space is small enough that it’s possible to reasonably bruteforce the hash, even on laptop hardware
