Abstract: With the rapid evolution of advanced image compression, DNN-based learned image compression has emerged as the promising approach for transmitting images in many security-critical applications, such as cloud-based face recognition and autonomous driving, due to its superior performance over traditional compression. There is a pressing need to fully investigate the robustness of a classification system post-processed by learned image compression. To bridge this research gap, we explore the adversarial attack on Learned Image Compression Classification System (LICCS) that targets image classification models that utilize learned image compressors as preprocessing modules. To perform an adversarial attack on an image within the LICCS, the goal is to introduce the adversarial perturbation δ to the source image X that causes the reconstructed adversarial examples g s (Q(g a (X+δ))) to be misclassified by the classification model, which can be formulated as follows:\begin{equation*}\begin{array}{ll} {\mathop {\arg \max }\limits_i f{{\left({{g_s}\left({Q\left({{g_a}\left({{\mathbf{X + \delta }}}\right)}\right)}\right)}\right)}_i} \ne y,}&{{\text{s}}{\text{.t}}{\text{.}}\parallel \delta {\parallel _p} \leq \varepsilon .} \end{array}\tag{1}\end{equation*}
