Google spots DDR4 weakness that could expose your PC to a system takeover


Google spots DDR4 weakness that could expose your PC to a system takeover, A new DRAM hacking technique might expose your DDR4 RAM to assaults and eventual system takeovers. Fortunately, Google is stepping up with the wise notion of making the findings public in the hopes of hastening a repair.

The software is a new variant of a known vulnerability called Rowhammer. The vanilla version of the software would compromise the data rattling around your RAM's memory cells by granting hackers ability to access one adjacent row, and modify the content of other memory addresses, by sending multiple access requests.

It's existed for a while and, according to Neowin, it came about thanks to an "electrical coupling phenomenon in silicon chips which bypasses software- and hardware-based protection."

Previously, DRAM makers could safeguard against Rowhammer attacks by installing circuitry that detected and blocked the nefarious behavior in DDR3 chips. They assumed it was all over. However, with the introduction of DDR4, it has been shown that the curse of Rowhammer is still a menace, operating via TRRespass and other techniques.
