  • It’s not reading the contents of RAM via EM emanations, it’s using the EM emanations caused by certain memory access patterns as a side channel to exfiltrate data. Of course, that data could be anything, including whatever is in RAM, but the point is that you need to be running the code that generates the necessary memory access patterns to transmit the bits of data. This is not like TEMPEST where you can reconstruct a video display just using the emanations.

    What happened

    The code that was previously here has been taken down at AMD’s request. The code was released with AMD’s approval through an email. AMD’s legal department now says it’s not legally binding, hence the rollback. Before anyone asks: I have received no legal threats or any communication from NVIDIA.

    What now

    At this point, one more hostile corporation does not make much difference. I plan to rebuild ZLUDA starting from the pre-AMD codebase. Funding for the project is coming along and I hope to be able to share the details in the coming weeks. It will have a different scope and certain features will not come back.
