What Was Your Prompt? A Remote Keylogging Attack on AI Assistants

no code implementations14 Mar 2024 Roy Weiss, Daniel Ayzenshteyn, Guy Amit, Yisroel Mirsky

In this paper, we unveil a novel side-channel that can be used to read encrypted responses from AI Assistants over the web: the token-length side-channel.

SoK: Reducing the Vulnerability of Fine-tuned Language Models to Membership Inference Attacks

no code implementations13 Mar 2024 Guy Amit, Abigail Goldsteen, Ariel Farkash

We provide the first systematic review of the vulnerability of fine-tuned large language models to membership inference attacks, the various factors that come into play, and the effectiveness of different defense strategies.

Transpose Attack: Stealing Datasets with Bidirectional Training

1 code implementation13 Nov 2023 Guy Amit, Mosh Levy, Yisroel Mirsky

In addition, in this work we show that neural networks can be taught to systematically memorize and retrieve specific samples from datasets.

YolOOD: Utilizing Object Detection Concepts for Multi-Label Out-of-Distribution Detection

no code implementations5 Dec 2022 Alon Zolfi, Guy Amit, Amit Baras, Satoru Koda, Ikuya Morikawa, Yuval Elovici, Asaf Shabtai

In this research, we propose YolOOD - a method that utilizes concepts from the object detection domain to perform OOD detection in the multi-label classification task.

The Security of Deep Learning Defences for Medical Imaging

no code implementations21 Jan 2022 Moshe Levy, Guy Amit, Yuval Elovici, Yisroel Mirsky

Deep learning has shown great promise in the domain of medical image analysis.

FOOD: Fast Out-Of-Distribution Detector

1 code implementation16 Aug 2020 Guy Amit, Moshe Levy, Ishai Rosenberg, Asaf Shabtai, Yuval Elovici

Deep neural networks (DNNs) perform well at classifying inputs associated with the classes they have been trained on, which are known as in distribution inputs.

Out-of-Distribution Detection Out of Distribution (OOD) Detection

GIM: Gaussian Isolation Machines

no code implementations6 Feb 2020 Guy Amit, Ishai Rosenberg, Moshe Levy, Ron Bitton, Asaf Shabtai, Yuval Elovici

In many cases, neural network classifiers are likely to be exposed to input data that is outside of their training distribution data.
