Benchmarking Security Risk Detection and Verification in Open Agentic Skill Ecosystems
Ismail Hossain, Sai Puppala, Zhuoran Lu +2
Open agent platforms allow community contributors to publish reusable skills that agents can invoke at runtime. This extensibility also creates a supply-chain risk: malicious contr…
The Misattribution Gap: When Memory Poisoning Looks Like Model Failure in Agentic AI Systems
Tanzim Ahad, Ismail Hossain, Md Jahangir Alam +3
Multi-agent AI pipelines typically assume that agent misconduct originates from model misalignment. We identify a structural failure in this assumption, the \emph{Misattribution Ga…
The Art of the Jailbreak: Formulating Jailbreak Attacks for LLM Security Beyond Binary Scoring
Ismail Hossain, Tanzim Ahad, Md Jahangir Alam +3
Jailbreak attacks -- adversarial prompts that bypass LLM alignment through purely linguistic manipulation -- pose a growing operational security threat, yet the field lacks large-s…
Semantic Intent Fragmentation: A Single-Shot Compositional Attack on Multi-Agent AI Pipelines
Tanzim Ahad, Ismail Hossain, Md Jahangir Alam +4
We introduce Semantic Intent Fragmentation (SIF), an attack class against LLM orchestration systems where a single, legitimately phrased request causes an orchestrator to decompose…
Agent-Fence: Mapping Security Vulnerabilities Across Deep Research Agents
Sai Puppala, Ismail Hossain, Md Jahangir Alam +5
Large language models are increasingly deployed as *deep agents* that plan, maintain persistent state, and invoke external tools, shifting safety failures from unsafe text to unsaf…

LLM-Guided Dynamic-UMAP for Personalized Federated Graph Learning
Sai Puppala, Ismail Hossain, Md Jahangir Alam +2
We propose a method that uses large language models to assist graph machine learning under personalization and privacy constraints. The approach combines data augmentation for spar…
Variational Gaussian Mixture Manifold Models for Client-Specific Federated Personalization
Sai Puppala, Ismail Hossain, Md Jahangir Alam +1
Personalized federated learning (PFL) often fails under label skew and non-stationarity because a single global parameterization ignores client-specific geometry. We introduce VGM$…
