# POC for meltdown/spectre

I just wanted to see if this really works, and it actually does. Scary!

It reads out the `TEST_PHRASE` using the timing attack (in its own process).

**Note:** This will only work on Intel "Haswell" and later, since it uses

the TSX extensions to mitigate the processor trap.

Alternatively, by changing the macro `TEST_IN_OWN_PROCESS` to 0, you can

specify an address and length on the command line, and output raw data to pipe

into `strings`. In this case, it uses Intel's TSX to prevent crashing when

attempting to access the mem location, just like the meltdown paper says.

Tested on OS X 10.12.6

Update: OS X has a fix available now, so the PoC only works in its own process

memory anymore.
