Goals

  • Find out more exploitable regions inside the libtriton.so library.

What I worked on

  • Started thinking about the design of my automated LLVM exploitation tool.
  • Started reading Designing Data-Intensive Applications (DDIA)
  • Read a chapter in Fluent Python about objects and their aliasing.

Key Insights

  • Although tuples are immutable, the data that they contain can be mutable, hence the data resident within a tuple can change.
  • Aliasing and shallow copies of mutable data types can lead to subtle programming bugs.
  • Never use mutable data types as default parameters in fucntions.

Questions / Confusions

  • I still need to how predicate in ptx can be manipulated to skip instructions.

Ideas / Hypotheses

  • I can generalize the attack surface of LLVM to different targets like AMDGPU, RISC-V etc.

Papers / Resources

  • None

Next Steps

  • Create an end-to-end automated framework for finding out the exploitable flips.

Introspection

  • Today was a good day in terms of my education as a gained a lot of knowledge about python internals, cloud deployments, data warehouses and data lakes.
