Side Channel Attacks in 4G and 5G Cellular Networks
summary
Describes ToRPEDO, a side-channel attack that leverages the fixed timing of paging occasions in 4G/5G to link a victim’s soft identity (for example a phone number or Twitter handle) to that paging occasion by an adversary nearby. Shows how that link can be used to confirm a victim’s coarse location, inject forged paging messages, and carry out denial-of-service against the victim using standard cellular paging mechanisms.
