Video: Picking Up The Trash – Exploiting Generational GC For Memory Analysis

Adam Pridgen discusses his research at DFRWS EU 2017.

Pridgen: Thank you, everybody, for being here. I know that I stand between you and lunch. I’m here presenting research on behalf of myself and my colleagues Dan and Simson. So let’s get started.

As you all know, Java uses automatic memory management. Automatic memory management means that the developers no longer have control over the memory that they’re allocating or deallocating. A lot of this happens behind the scenes, using the garbage collector. And in the case of Java, it uses a generational garbage collector but other managed runtimes use different types of garbage collectors. What this really means is data cannot be explicitly destroyed, so that means if we have some type of application that we want to protect sensitive data with, or protect sensitive data, we can’t do it.
