Security experts devised a new attack technique dubbed Throwhammer that could be exploited by attackers to launch Rowhammer attack on a system in a LAN. Rowhammer is classified as a problem affecting some recent DRAM devices in which repeatedly accessing a row of memory can cause bit flips in adjacent rows, this means that theoretically, an attacker can change any value of the bit in the memory. The attack requires a high-speed network of at least 10Gbps to trigger a bit flip through hundreds of thousands of memory accesses to specific DRAM locations within tens of milliseconds.”]
