Opal Hard Drives for Ransomware Resilience

Senior Staff, the Johns Hopkins University / Applied Physics Laboratory

Ransomware is crippling industry and government alike. Paying the ransom doesn’t guarantee you’ll get your files back, but it funds the criminals who will continue on. Restoring from traditional network backups takes time, and never gets you back to the system you had before the attack. In response, we have developed a resilient, local malware restore and recovery capability, capable of quickly restoring OS images onto “bare metal” after an attack or misconfiguration, useful for many applications.

I will discuss the technical details, including a description of the Opal hard drive specification, the Trusted Computing Group’s Trusted Platform Module (TPM), and how we secure secrets needed for WUBU – Wake-Up-Back-Up. I’ll talk through some of the open-source technologies that we used to build our solution. WebEx willing, I will give a live demonstration of a ShinoLocker ransomware infection, followed by an “as if nothing ever happened” recovery that takes only ten minutes.
