I'm looking forward to presenting my paper, "Continuous User Behavior Monitoring using DNS Cache Timing Attacks" at NDSS next week! We mount an Evict+Reload-style attack on the local DNS cache, detecting recently accessed domains and evicting to continuously monitor new accesses.

I am happy to announce that my first paper has been accepted at USENIX Security! We propose TEEcorrelate, a mitigation that statistically decorrelates reported performance counters from real ones during TEE execution.
