## Summary  
The paper tackles the problem of evaluating AI agents’ reverse‑engineering (RE) abilities on real‑world binaries, where benchmark data must be unseen and protected by anti‑analysis measures to avoid shortcuts. It introduces **SRE‑Bench**, a contamination‑free RE benchmark built from scratch with 262 binary instances and 1 572 deterministically graded tasks. The authors evaluate five frontier LLMs (GPT‑5.6‑sol, Claude‑Opus‑5, GPT‑5.5, Grok‑4.5, GLM‑5.2) and show that even the strongest model solves only about one‑third of the instances. This work establishes a rigorous testbed for agentic cybersecurity by bridging source‑code security expertise with binary analysis.

## Key Contributions  
- SRE‑Bench is the first realistic, contamination‑free RE benchmark composed entirely of private, real‑world programs and 44 in‑house anti‑analysis primitives.  
- The evaluation demonstrates that top models like GPT‑5.6‑sol achieve only a 61.4 % per‑instance score and fully solve just 31.5 % of the instances, revealing a significant gap between source‑code analysis and binary analysis.  
- Controlled ablations confirm that both contamination control (preventing model shortcuts) and realistic scale (matching real software complexity) are essential for valid benchmark performance.

## Methodology  
The authors assembled SRE‑Bench by RE experts over 5 000 hours, selecting 19 private programs averaging 16.9 K lines of code each. They then designed 44 anti‑analysis primitives to protect the binaries from model leakage and built 262 binary instances with deterministically graded tasks that can be solved or not based on a fixed algorithm.

## Results  
Across GPT‑5.6‑sol, Claude‑Opus‑5, GPT‑5.5, Grok‑4.5, and GLM‑5.2, the best model scores 61.4 % per instance with only 31.5 % fully solved instances. Ablations show that removing contamination control or reducing program size dramatically improves performance, underscoring their necessity.

## Significance  
This work highlights a major frontier: transferring source‑code security expertise to binary analysis, which is crucial for building robust agentic cybersecurity defenses. SRE‑Bench provides a standardized, reproducible benchmark that can guide future model development and research in AI‑driven reverse engineering.
