Le taux de réussite d’attaque (ASR) évalue les jailbreaks contre les grands modèles linguistiques sans tenir compte des appels répétés au modèle de victime. Cependant, chaque appel supplémentaire donne au système déployé une autre occasion de détecter l’attaque et d’intervenir. Nous introduisons $\mathrm{ASR}_{\mathrm{STEP}}$, ce qui pénalise les appels de modèle de victime supplémentaires tout en conservant les jugements de succès binaires. Notre évaluation considère GCG, PAIR avec un budget d’étape et une ligne de base PAP à un seul pas sur JailBreakBench sur trois familles de modèles. Les scores de GCG diminuent de 7,0 à 8,7 points de pourcentage après

Abstract

Attack success rate (ASR) evaluates jailbreaks against large language models without accounting for repeated calls to the victim model. Yet each additional call gives the deployed system another opportunity to detect the attack and intervene. We introduce $\mathrm{ASR}_{\mathrm{STEP}}$, which penalizes additional victim-model calls while retaining binary success judgments. Our evaluation considers GCG, PAIR with a step budget, and a single-step PAP baseline on JailBreakBench across three model families. GCG's scores decrease by 7.0-8.7 percentage points after discounting, while PAP's remain unchanged. While for PAIR attack, we see a wider discounting range between 3.4-12 percentage points, showing that the "step" quantity differs per iterative strategy. Reporting both metrics makes the discount due to repeated victim-model interaction explicit. Code is available here: https://github.com/SuELS-Group/beyond_asr.
