      ECCploit is the first Rowhammer attack to defeat error-correcting code.

      In early 2015, researchers unveiled Rowhammer, a cutting-edge hack that exploits unfixable physical weaknesses in the silicon of certain types of memory chips to transform data they stored. In the 42 months that have passed since then, an enhancement known as error-correcting code (or ECC) available in higher-end chips was believed to be an absolute defense against potentially disastrous bitflips that changed 0s to 1s and vice versa.

      Research published Wednesday has now shattered that assumption....
