Нами было рассказано о практических аспектах применения dynamic binary instrumentation engines (на примере PIN. Для анализа покрытия кода при фаззинге. Но очевидно, что столь мощные технологии годятся для решения и более сложных задач: в этот раз речь будет идти про использование PIN для построения карты исполнения кода в виде дерева вызовов различных процедур.

Речь шла про обход детектирования скрытого исполняемого кода на примере популярных антируткит-утилит.

My aimful life: Exploiting UEFI boot script table vulnerability

Another web log by Dmytro Oleksiuk aka Cr4sh. Friday, February 6, 2015. Exploiting UEFI boot script table vulnerability. Around one month ago, at 31-st Chaos Communication Congress, Rafal Wojtczuk and Corey Kallenberg presented an excellent research: "Attacks on UEFI security, inspired by Darth Venamis's misery and Speed Racer" ( video. Is very interesting because at this moment it's one of the best publicly known vulnerabilities that allows to get access to the SMM. Also, while reading this post you sho...
