An intelligent combination of timing Prime + Probe attack and row-buffer collision is shown to induce bit flip faults in a 1024 bit RSA key on modern processors using realistic number of hammering attempts ...
In this paper, we develop a methodology to combine timing analysis to perform the hammering in a controlled manner to create bit flips in cryptographic keys which are stored in memory. ...
Combining Timing Analysis and Rowhammer In this section we discuss the development of an algorithm to induce bit flip in the secret exponent by combining timing analysis and DRAM vulnerability. ...

We find that the DRAM modules we analyze are vulnerable to RowHammer, having bit flips in up to 99.9% of all DRAM rows. ...
We show how U-TRR allows us to craft RowHammer access patterns that successfully circumvent the TRR mechanisms employed in 45 DRAM modules of the three major DRAM vendors. ...
