Monero is a privacy-focused cryptocurrency that incorporates anonymity networks (such as Tor and I2P) and deploys the Dandelion++ protocol to prevent malicious attackers from linking transactions with their source IPs. However, this paper highlights a vulnerability in Monero's integration of the Tor network, which allows an attacker to successfully deanonymize transactions originating from Monero Tor hidden service nodes at the network-layer level.
