A team of academics from the Vrije University in Amsterdam has developed a new hacking technique that uses embedded graphics processing units (GPUs) and support for WebGL to carry out a Rowhammer attack. A Rowhammer is when an attacker bombards RAM memory cell rows with constant read-write operations causing the memory cells to change their electrical charge, which inherently modifies the stored data bits from 1 to 0 and vice-versa, altering the information saved in a computer’s memory.
