Beyond Tokens: NumAnchor for Address-Grounded Numeric Operand Representation in Assembly Language Models
Kun Liu, Keith Mitchell, Xin Hu +5
Assembly language models (ALMs) are becoming important for automated binary analysis, yet their token-level interfaces often obscure numeric-like operands. In two corpora, such ope…
Long-Range Indirect Control-Flow Prediction in Stripped Binaries via Dual Virtual Hubs and Multi-Task Graph Learning
Kun Liu, Zhengming Ding, Chenke Luo +4
Recovering indirect control-flow (ICF) edges is fundamental to binary security analysis, yet existing methods struggle with long-range dependencies, isolate different ICF types, an…
Beyond Tag Collision: Cluster-based Memory Management for Tag-based Sanitizers
Mengfei Xie, Yan Lin, Hongtao Wu +3
Tag-based sanitizers attach a small "key" to each pointer and a matching "lock" tag to its target memory object, enabling runtime verification of pointer-object consistency and hel…
Resolving Indirect Calls in Binary Code via Cross-Reference Augmented Graph Neural Networks
Haotian Zhang, Kun Liu, Cristian Garces +3
Binary code analysis is essential in scenarios where source code is unavailable, with extensive applications across various security domains. However, accurately resolving indirect…
Retrofitting XoM for Stripped Binaries without Embedded Data Relocation
Chenke Luo, Jiang Ming, Mengfei Xie +2
In this paper, we present PXoM, a practical technique to seamlessly retrofit XoM into stripped binaries on the x86-64 platform. As handling the mixture of code and data is a well-k…
