Academics from the Vrije University in Amsterdam, Holland, have published a research paper today describing a new variation of the Rowhammer attack.
For readers unfamiliar with the term, Rowhammer is the name of a class of exploits that takes advantage of a hardware design flaw in modern memory cards.
By default, a memory card stores temporary data inside storage units named cells, which are arranged on the physical silicon chip in multiple rows, in the form of a grid.
In 2014, researchers discovered that by reading a data stored on one row repeatedly, over and over again, they could create an electrical field that would alter data stored on nearby memory rows, causing either data corruption, or manipulating data in malicious ways.
