SMoTherSpectre: exploiting speculative execution through port contention

Autor: Bhattacharyya, Atri, Sandulescu, Alexandra, Neugschwandtner, Matthias, Sorniotti, Alessandro, Falsafi, Babak, Payer, Mathias, Kurmus, Anil

Spectre, Meltdown, and related attacks have demonstrated that kernels, hypervisors, trusted execution environments, and browsers are prone to information disclosure through micro-architectural weaknesses. However, it remains unclear as to what extent

Midas: Systematic Kernel TOCTTOU Protection

Autor: Bhattacharyya, Atri, Tesic, Uros, Payer, Mathias

Double-fetch bugs are a plague across all major operating system kernels. They occur when data is fetched twice across the user/kernel trust boundary while allowing concurrent modification. Such bugs enable an attacker to illegally access memory, cau

SpecROP: Speculative Exploitation of ROP Chains

Autor: Bhattacharyya, Atri, Marin, Andres Sanchez, Koruyeh, Esmaeil Mohammmadian, Abu-Ghazaleh, Nael, Song, Chengyu, Payer, Mathias

Speculative execution attacks, such as Spectre, reuse code from the victim’s binary to access and leak secret information during speculative execution. Every variant of the attack requires very particular code sequences, necessitating elaborate gad
