Rascals are always sociable, and the chief sign that a man has any nobility in his character is the little pleasure he takes in others company. Arthur Schopenhauer


LTESniffer is An Open-source LTE Downlink/Uplink Eavesdropper.

It first decodes the Physical Downlink Control Channel (PDCCH) to obtain the Downlink Control Informations (DCIs) and Radio Network Temporary Identifiers (RNTIs) of all active users. Using decoded DCIs and RNTIs, LTESniffer further decodes the Physical Downlink Shared Channel (PDSCH) and Physical Uplink Shared Channel (PUSCH) to retrieve uplink and downlink data traffic.

LTESniffer supports an API with three functions for security applications and research. Many LTE security research assumes a passive sniffer that can capture privacy-related packets on the air. However, non of the current open-source sniffers satisfy their requirements as they cannot decode protocol packets in PDSCH and PUSCH. LTESniffer: Open-source LTE Downlink/Uplink Eavesdropper
