iaik / drama Goto Github PK

hey...just wondering how could my machine does not have a single bit flip when I'm running your demo drama + rowhammer. My machine is a 6th Core I7, with two 8G DDR4.
thanks

Can an attacker observe that the address on the DRAM is read or written?Or can an attacker know the read after write pattern?

I tried your tool, but was not able to obtain the correct values. I've tried with different allocation sizes and even with different sets, althought I was sure to know which value to provide.

The README states that "the code contains hardcoded addresses and thresholds that are specific to [your] systems". Are there values I can tweak to get better results? If yes, which?

Currently the program quits always with Couldn't find set after 10 tries, giving up, sorry! or (seldom) with a std::bad_array_new_length exception. I didn't try to debug it and can't provide further information on it right now, but If you are interested to resolve this issue, I could provide additional information on my test system, RAM organization etc.

What should the expected number of sets be? The total number of sets of non-conflicting (at the row level) addresses?

For example, on a dual channel system, with 2 ranks/DIMM and DDR4 (16 banks), does that lead to 2 * 2 * 16 = 64 sets? Based on the default value of 8, I'm guessing that's not correct...
