Nethammer: Inducing Rowhammer Faults through Network Requests

Understand

A fundamental assumption in software security is that memory contents do not change unless there is a legitimate deliberate modification.

• Classical fault attacks show that this assumption does not hold if the attacker has physical access.
• Rowhammer attacks showed that local code execution is already sufficient to break this assumption.
• Rowhammer exploits parasitic effects in DRAM to modify the content of a memory cell without accessing it.
