ACM SURE Workshop @sureworkshop.bsky.social · 5d

Finally, stay in touch. We have an associated Discord (unorthodox, we know) to connect academics and practitioners: discord.gg/eVySXH7ZQ8

In fact, some of the attendees this year only made it due to the outreach on Discord. Come and chat!

SURE

The Workshop on Software Understanding and Reverse Engineering (SURE), hosting conversations on associated topics. From decompilation to source visualizati

Keep, a lookout for our executive summary of papers/discussions/conclusions at SURE 2025 for those who could not attend IRL. We will post it in the coming days.

ACM SURE Workshop @sureworkshop.bsky.social · 5d

CCS has come to a close, and so has the first-ever SURE Workshop. We want to thank the authors, the PC, @moyix, our panel, and CCS for making SURE a success. We felt the support for this research area (the room was packed out for more than half the day).

See you all next year!

In the special sub-area of type inferencing on binary code, Noriki's work explores the recovery of structs and how different GNN architectures may have better performance.

On our last presented work at SURE, we have Noriki Sakamoto presenting "Toward Inferring Structural Semantics from Binary Code Using Graph Neural Networks"

Indeed, LibIHT is more robust. They achieve better results on binaries that attempt to evade their analysis.

ACM SURE Workshop @sureworkshop.bsky.social · 10d

The magic happens at the kernel level. Their new tool LibIHT (github.com/libiht/li...), is implemented both at the user-space and kernel-space level.

This is important for speed and robustness against evasion techniques.

Often, when static analysis tools do not work, you need to get down in the weeds of a program and start dynamically analyzing it.

In Thomason's work, he explores a way to be more robust and efficient by utilizing hardware features for dynamic analysis.

ACM SURE Workshop @sureworkshop.bsky.social · 10d

We're so back, and on our last session: Applications & Future Work.
Changyu "Thomason" Zhao is presenting "LibIHT: A Hardware-Based Approach to Efficient and Evasion-Resistant Dynamic Binary Analysis".

He is presenting virtually.

Now, you got your crazy code, how do you select which functions in the code to obfuscate and evaluate on?

Functions must be "sensitive" and "central". Sensitive: has sensitive info like a uid or gid or a password. Central: many other functions should depend on it (calls).

Real world programs in their set need:
- unique functionality
- complex code
- ...

Some real programs: OpenSSL, QEMU, SQLite, curl, ... all difficult targets that are already hard to analyze, so they are not obfuscated.

ACM SURE Workshop @sureworkshop.bsky.social · 10d

An interesting observation: obfuscation is really expensive on the CPU. Real programs don't obfuscate the entire program; they only obfuscate critical code locations like license checks.

So they construct their dataset with that in mind.

Dongpeng argues that many modern works in deobfuscation don't work on large complex programs. Instead, they are mostly tested on toy programs that are not real-world.

To make a more useful evaluation, they explore how real obfuscation is used.

ACM SURE Workshop @sureworkshop.bsky.social · 10d

We're on our last talk of the session, remaining with the obfuscation topic. Dongpeng Xu is presenting "DEBRA: A Real-World Benchmark For Evaluating Deobfuscation Methods" in the place of Zheyun Feng.

Interesting question: do specific features seem to matter more for the models? Example: constants.

So far, the answer is unclear. These models are very black-box and require more explainability.

ACM SURE Workshop @sureworkshop.bsky.social · 10d

Takeaways:
- Training on obfuscation does help models, but it is not a silver bullet. This solution does not work well on obfuscation tech it has never seen before.

Some results: you train on obfuscation, and it turns out the model does do better (with BinShot) on obfuscated code. However, training it on specific types of obfuscation tech matters. For instance, training on control flow flattening may not help at all with MBA.

ACM SURE Workshop @sureworkshop.bsky.social · 10d

The reasoning task: binary code similarity detection. Do these two code snippets come from an identical source, and does obfuscation stop it?

1

ACM SURE Workshop @sureworkshop.bsky.social · 10d

They evaluate public obfuscation tools such as an LLVM obfuscator and the classic tool Tigress.

They have a few questions, one interesting one is:
Does training on obfuscated code actually make the models better at reasoning on them?

1

ACM SURE Workshop @sureworkshop.bsky.social · 10d

When reasoning on code, does it matter if it is obfuscated? The answer feels like a strong YES; however, how much does it matter for AI?

Jiyong's work explores this idea in a measurable way.

ACM SURE Workshop @sureworkshop.bsky.social · 10d

Next up is "On the Learnability, Robustness, and Adaptability of Deep Learning Models for Obfuscation-applied Code," presented by Jiyong Uhm of Sungkyunkwan University.

To run those tests, you can use LLMs! They get the input from decompilation and try to take the multiple-choice guess. It's important you measure probabilities along the way.
