Safety-aligned LLMs suffer from two failure modes: jailbreak (responding to harmful inputs) and over-refusal (declining benign queries). Existing vector steering methods adjust the magnitude of answer vectors, but this creates a fundamental trade-off—reducing jailbreak increases over-refusal and...

Binary Code Similarity Detection (BCSD) plays a vital role in various security applications, including vulnerability identification, malware analysis, and code plagiarism detection. With the growing adoption of deep neural networks (DNNs), substantial progress has been made in recognizing and cla...

Recently, there is an emerging trend of using Large Language Models (LLMs) to generate Programmable Logic Controller (PLC) code automatically, resulting in commercialized products such as Siemens Industrial Copilots. While such LLM-driven products have the potential to transform the way control e...
