"I can say I'm John Travoltabut I'm not John Travolta": Investigating the Impact of Changes to Social Media Verification Policies on User Perceptions of Verified Accounts In this paper, we propose a general defense framework called PatchGuard that can achieve high provable robustness while maintaining high clean accuracy against localized adversarial patches. USENIX Security '24 "I Don't Know If We're Doing Good. Final papers due: Tuesday, October 5, 2021; Artifact submission deadline: Wednesday In this paper, we first demystify the underlying mechanism of MBA obfuscation. Our attack enables a malicious client to learn model weights with 22x--312x fewer queries than the best black-box model-extraction attack and scales to much deeper networks. Artifact Submission Guidelines Step 1. We are, therefore, offering an opportunity to authors of papers from the 2020 and 2021 USENIX Security Symposium to present their papers as posters this year in Boston. In this paper, for the first time, we show that an adversary can defeat DNN-based traffic analysis techniques by applying adversarial perturbations on the patterns of live network traffic. Based on a machine-readable specification of a CPU's ISA, Osiris generates instruction-sequence triples and automatically tests whether they form a timing-based side channel. Our in-depth study reveals a hidden two-way feature regarding MBA transformation between 1-bit and n-bit variables.
