Chimera: Harnessing Multi-Agent LLMs for Automatic Insider Threat Simulation

Insider threats remain a critical yet difficult-to-detect security risk in enterprise environments, where malicious actions are often embedded in subtle, legitimate-looking behaviors. Although machine-learning-based insider threat detection (ITD) methods have shown promise, their effectiveness is fundamentally limited by the scarcity of high-quality, realistic training data. Enterprise data is rarely accessible due to sensitivity, while existing public datasets are small, and synthetic datasets often lack semantic richness, behavioral realism, and generalizability.  We present Chimera, an LLM-based multi-agent framework that simulates realistic benign and malicious insider behaviors and generates enterprise-scale system logs. Chimera models employees with fine-grained roles and organizational dynamics. We deploy Chimera to instantiate with 15 real-world-inspired insider attacks across three representative data-sensitive scenarios to construct ChimeraLog. Human and quantitative evaluations demonstrate the dat… Subtitle: Pre-Conference Talk by YU Jiongchi. Contact: scisseminar@smu.edu.sg.

Motor-Mediated Creativity: Bridging Embodied Skill Training and Digital Expression

Expressive digital drawing requires nuanced motor control, subtle variations in pressure, velocity, and rhythm that convey affect and style. While experts develop this embodied fluency through years of practice, novices struggle to produce marks that match their intentions, creating a gap between vision and execution. We propose motor-mediated creativity: treating motor training as integral to digital expression. Our system, MOTUS, instantiates this through structured practice of expressive primitives, expert-referenced feedback, and ideation prompts that encourage exploration. We report a two-stage investigation. A formative study characterized: (a) novice challenges in motor fluency, (b) examined how different feedback types, including corrective feedback, helped participants understand their mistakes, (c) how prompts, generic or embodied, support engagement with abstract expressive content. A controlled evaluation then linked fluency gains to subjective and expert ratings of expressiveness. Together, our f… Subtitle: Pre-Conference Talk by WITHANA KANKANAMALAGE Gevindu Ganganath Sumanasekara. Contact: scisseminar@smu.edu.sg.
