Abstract
A new 0-day vulnerability can be exploited to perform the most powerful-ever pulsing DoS attack, which is resulted from the DNS protocol design.
In GeekCon 2023, I presented our 0-day vulnerability to conduct pulsing DoS attack with Dashuai. We got the 2nd prize of GeekCon 2023 DAF (Defense & Attack Force) Contest. Our colleagues got two Winner prizes and the 1st prize of AVSS contest.
