• A Large-Scale Benchmark and Risk Assessment of Traffic Analysis Attacks on Cloud LLM Services

  Shahrooz Pouryousef, Jesus Lopez, Saeefa Rubaiyat Nowmi, Md Mahmuduzzaman Kamol, Moinul Hossain, Muoi Tran, Mohammad Saidur Rahman · 29 de septiembre de 2026

  Cloud-based Large language model (LLM) services create a network-level traffic side channel that can expose model, prompt, and task behavior despite encryption. From packet sizes, directions, timing, and burst structure alone, a passive local observer can infer the serving model, the user's prompt c…

• Unknown-Traffic Detection, Calibration and Shortcut Reliance in Distilled Encrypted-Traffic Classifiers over One Year

  Mahmoud Abbasi · 28 de septiembre de 2026

  Knowledge distillation is the standard way to compress encrypted-traffic classifiers for the edge, and almost all such work judges students by accuracy alone. We ask what else a student inherits: unknown-traffic detection, calibration, shortcut reliance, and whether any survives a year of drift. Res…

• FlowAtom: Atom-Based Evidence Aggregation for Multi-Label Website Fingerprinting

  Chongru Fan, Wentao Huang, Wei Wang, Zhenquan Ding, Jinqiao Shi, Wei Cai, Zhiyu Hao · 25 de septiembre de 2026

  Identifying the set of monitored websites in mixed encrypted traffic is challenging because an individual flow often provides only partial evidence of website identity. To address this challenge, we propose FlowAtom, which constructs shared prototypes, called Atoms, from flow representations without…

• Feature Suppression and Differential Privacy for Residential Traffic Classification: A Two-Home Federated Study

  M\'arton P\'al Lipcsey-Magyar, Adrian Pekar · 22 de septiembre de 2026

  Residential traffic classification supports service management, but learning across homes must account for heterogeneous traffic and privacy constraints. Privacy-aware training may impose uneven costs across traffic categories. We study this tradeoff in simulated two-client federated learning using …

• Beyond Measurement Metrics: A Human-Centered Framework for Semantic Validation of Network Traffic Classification

  Igor Cherepanov, David Sessler, Alex Ulmer, Thorsten May, J\"orn Kohlhammer · 16 de septiembre de 2026

  Machine learning (ML) has become the dominant approach for network traffic classification, achieving very high predictive performance. However, a model is only valuable if it learns semantically meaningful and trustworthy patterns rather than exploiting spurious correlations. Conventional evaluation…

• Chameleon: Robust Defense Against Tor Website Fingerprinting via Many-to-Many Traffic Morphing

  Yuwen Cui, Kai Wei, Kehan Shen, Ning Wang, Zhuo Lu, Yao Liu, Guangjing Wang · 21 de agosto de 2026

  Website fingerprinting (WF) attacks can infer users' browsing activities from encrypted Tor traffic by exploiting side-channel features. Although many WF defenses have been proposed, we find that most existing defenses create learnable web trace mapping features. We further show that robustness agai…

• PERO: Efficient Robust Post-Training Foundation Models for Encrypted Traffic Classification

• Enhancing Anomaly Resilience in Research Networks: A Large-Scale Forecasting Benchmark for Dynamic Security Baselining

  Mohammad Arafath Uddin Shariff, Byrav Ramamurthy · 7 de agosto de 2026

  Research and Education Networks (RENs) serve as critical infrastructure for scientific discovery, yet they face a unique security paradox: their normal traffic patterns which are characterized by massive, bursty "elephant flows" are statistically indistinguishable from volumetric attacks such as DDo…

• Learning Compression Rules for Network Traffic

  Quentin Lampin (Orange Research), \'Eloi Sainte-Beuve (Orange Research, Universit\'e Grenoble Alpes), Louis-Adrien Dufr\`ene (Orange Research), Guillaume Larue (Orange Research), Massih-Reza Amini (Universit\'e Grenoble Alpes) · 6 de agosto de 2026

  We study the problem of learning compact rule-based compressors for structured network traffic. Each packet is a record of header fields that are highly redundant within a flow, and a compressor is a small set of rules matching such records and replacing predictable fields with short codes. We cast …

  Xavier Marjou, Lucas Tamic, Ilan Jaffeux-Cheniout · 31 de julio de 2026

  Large language models (LLMs) offer powerful reasoning capabilities for network traffic analysis, but standard capture formats and their textual equivalents are prohibitively verbose, overflowing LLM context windows by two orders of magnitude. We present PCAP-LM, a flow-centric, LLM-native text repre…

  Sherwin Vishesh Jathanna · 30 de junio de 2026

  LLM-based assistants transmit user queries verbatim to third-party API endpoints that lie outside the user's audit or control. When those queries contain personally identifiable information (PII), the data persists on remote infrastructure subject to breach, subpoena, or policy change. Placeholder r…

• ML-Powered LDAP Reconnaissance Detection using Weak Supervision

  Shaefer Drew, Edward Raff, Michael Brautbar, Yaron Zinar, Benjamin Malmberg, Dor Agron, Sagi Sheinfeld, Avraham Kama, Asaf Romano · 30 de junio de 2026

  Lightweight Directory Access Protocol (LDAP) is a protocol that allows users to query and modify Active Directory (AD) data. By default, all users have read access to all AD data through LDAP, making it a common initial tool for reconnaissance when a threat actor first compromises an identity. To ca…
