This paper addresses the challenge of detecting collaborative fraud within massive heterogeneous account graphs representing online payment platforms
research note
This paper asks a simple but important question for bot-defense and biometric security: if a generative human-animation model makes a video look convincing, does it also preserve the subject’s gait…
research note
This paper investigates whether promotional social bots on Twitter exhibit systematic behavioural changes over time, challenging the common assumption that bot behaviours and associated features re…

This paper investigates the privacy practices and risks associated with browser agents—tools that automate web browsing using large language models (LLMs)
research note
This paper addresses the critical problem of detecting phishing URLs, a major cybersecurity threat used to steal personal information
research note
This paper addresses the problem of perfect Lp sampling in turnstile data streams, focusing on vectors x∈{−poly(n),...,poly(n)}^n updated by turnstile operations, and sampling indices with exact pr…
research note
This paper studies a failure mode the authors call “confusion” for multimodal large language models (MLLMs): instead of trying to make the model follow a malicious instruction or predict the wrong …
research note
DLADiff addresses a gap that most prior anti-customization work leaves open: defenses for diffusion-model fine-tuning existed, but zero-shot identity customization (for example, FaceID-style method…
research note
This paper studies how Active Queue Management (AQM) algorithms influence modern speed test measurements, specifically metrics related to latency under load and throughput variability
research note
This paper tackles a concrete limitation in wireless foundation models: most prior WFMs are modality-specific, even though wireless systems expose multiple views of the same propagation event, incl…
