kernel: ceph: kernel: Ceph: exploit of hardcoded IVECs, in a misuse of AES, resulting in authentication bypass

A flaw was found in the CephX authentication protocol used by Ceph, a distributed storage system. CephX uses AES-128-CBC encryption with a hardcoded initialization vector and no message authentication HMAC, making it vulnerable to the same class of unauthenticated-encryption attacks that...

A Hybrid Cluster-Based Classification Model for Anomaly Detection in Unbalanced IoT Networks

Detecting anomalies in Internet of Things IoT networks is a critical security challenge, often hampered by highly imbalanced and diverse network traffic datasets. Standard classifiers struggle to perform well across all traffic types. This paper proposes a hybrid detection model to address this...
