Side Channel Attacks in 4G and 5G Cellular Networks

Дата: 18.03.2020. Автор: CISOCLUB. Категории: Подкасты и видео по информационной безопасности

This talk first presents how the fixed nature of paging occasions can be exploited as a side-channel by an adversary in the vicinity of a victim to associate the victim’s soft-identity (e.g., phone number, Twitter handle) with its paging occasion, with only a modest cost, through an attack dubbed ToRPEDO (TRacking via Paging mEssage DistributiOn). Consequently, we demonstrate how ToRPEDO can enable an adversary to verify a victim’s coarse-grained location information, inject fabricated paging messages, and mount denial-of-service attacks.
