Two researchers have discovered a new timing channel attack technique that remains effective even if multiple processes are running on a system.
Called DABANGG, the newly proposed technique improves the effectiveness of flush-based attacks such as Flush+Reload and Flush+Flush, researchers Anish Saxena and Biswabandan Panda from the Indian Institute of Technology Kanpur claim in a research paper.
DABANGG is a timing channel attack that is resilient to system noise and can improve the effectiveness of attacks such as Spectre.
Essentially, DABANGG attacks are flush-based attacks, meaning that all of the mitigation techniques that apply to Flush+Reload and Flush+Flush attacks are applicable to DABANGG refined attacks.
"The improved, noise resilient DABANGG-enabled attacks pose a significant challenge to the micro-architectural security community. DABANGG-enabled attacks have all of the perks of flush based attacks while being significantly more accurate and precise, making the flush based attacks more practical," the researchers conclude.
