As the world gradually adopts and transitions to using 5G for mobile, operational technology (OT), automation and Internet-of-Things (IoT) devices, a secure 5G network infrastructure remains critical. Recently, the Automated Systems SEcuriTy (ASSET) Research Group have released a new framework named SNI5GECT [pronounced as Sni-f-Gect (sniff + 5G + inject)] that enables users of the framework to i) sniff messages from pre-authentication 5G communication in real-time and ii) inject targeted attack payloads in downlink communications towards User Equipments (UE). I had previously written about how 5G connections are established over here, hence I will be diving directly into the SNI5GECT framework. In this diary, I will briefly provide an overview of the SNI5GECT framework and discuss a new multi-stage downgrade attack leveraging the SNI5GECT framework.
