The world of IT has just witnessed the most unsettling attack resulting from the rowhammer exploit. The exploit can flip individual bits in the memory of a computer.
The technique is so precise that it can allow a single machine to start stealing data from other machines that are hosted on the same cloud.
Until now, the Rowhammer exploit was considered a clumsy attack tool because it wasn’t really good enough to control where the data corrupting bits happened on a machine. Up till now, this attack was only considered a glitch until recently.
It is now capable of manipulating deduplication operations that are very common amongst cloud hosts to save memory.
