Rowhammer Attack
Rowhammer Attack is a type of computer security vulnerability that allows an attacker to read or write on the memory cells of other programs running on a computer without authorization. This attack works by repeatedly accessing a row of cells in memory, causing “bit flips” in nearby rows. If these bit flips occur in the right places, an attacker can trick the computer into performing unexpected actions or lead to unauthorized access. The Rowhammer Attack takes advantage of a hardware flaw in modern DRAM (Dynamic Random Access Memory) chips, which were not designed to anticipate such attacks. This vulnerability can be exploited in several ways, including over the internet, via maliciously-crafted websites, or through mail attachments. To protect against Rowhammer attacks, computer experts advise keeping systems up-to-date with the latest patches, running security software, and frequently backing up important data.
