Rowhammer
Rowhammer is a computer security issue that happens because of a weakness inside the way that computer memory is designed. It’s a type of attack where hackers can cause some memory locations to flip values quickly, which can cause serious problems for the computer.
Think of computer memory like a big grid of tiny boxes. Each box can hold a certain amount of information, like a number or a letter. When the computer needs to access certain information, it goes to that box and reads what’s inside.
But what if a hacker could force the computer to read the wrong information? That’s what Rowhammer does.
By constantly accessing certain memory locations in a rapid-fire way, a hacker can cause other memory locations nearby to flip as well. It’s sort of like shaking a bowl of marbles and causing some of them to move into different positions.
If a hacker can make the computer read the wrong information, they might be able to do things like steal passwords, take control of the computer, or cause it to crash unexpectedly.
Overall, Rowhammer is a serious issue that computer scientists and security experts are working hard to fix. By strengthening the design of computer memory, we can try to prevent this kind of attack in the future.
