Origin of Rowhammer

Rowhammer was first discovered by researchers from Carnegie Mellon University in 2014. They found that by rapidly accessing rows of memory cells, they could induce "bit flips" in nearby rows. This discovery shook the tech industry as it revealed a significant security threat that could potentially compromise the integrity of systems and data.

Practical Application of Rowhammer

One practical application of Rowhammer is in the realm of cybersecurity. Attackers can exploit this vulnerability to bypass security measures and gain unauthorized access to sensitive information. By targeting specific memory locations, attackers can manipulate data or execute arbitrary code, posing a severe threat to both individual users and organizations.

Benefits of Rowhammer

While Rowhammer poses a significant security risk, researchers and developers have also leveraged this vulnerability for beneficial purposes. One such application is in the field of fault injection testing. By intentionally inducing bit flips in memory, researchers can evaluate the robustness of hardware and software systems against potential errors and vulnerabilities. This proactive approach helps in identifying and mitigating potential weaknesses before they can be exploited by malicious actors.
