Past Present Logic Issues Exploitation Techniques Physical Domain in Software Mitigation Efforts Physical hardware cannot be changed in the field Vendors build in "Survivability features" Microcode is the most common used tool for mitigations Other firmware is also used "Chicken bits" to disable / change behavior Some issues are best mitigated in software Mitigations are not always possible/reasonable and almost difficult and time-consuming to engineer Prevention Pre-silicon Post-silicon Future Take Aways

Jolio and Yenzo discusses new attack vectors on Deep Neural Network (DNN) executables, specifically focusing on side-channel and bit-flip vulnerabilities. Here's a summary of the key points: DNN Executables and Vulnerabilities: The talk begins by explaining that cloud service providers deploy machine learning models as valuable services. Attackers can exploit side-channels to learn about the architecture of these models, which then opens the door for other attacks. The speakers investigate if DNN executables, created through deep learning compilation for performance, are also vulnerable. Deep Compilation and Side-Channels: Deep…
