Researchers at ETH Zurich have introduced Phoenix, a novel Rowhammer attack targeting DDR5 memory that can manipulate data, steal encryption keys, and escalate privileges by exploiting weaknesses in the memory's TRR mechanism. This attack highlights ongoing vulnerabilities in memory security despite manufacturer defenses and emphasizes the need for improved countermeasures. The study also underscores that Rowhammer attacks remain a significant threat across different generations of memory modules.
