QDCR: DNS–QUIC Cross-Protocol Traffic Amplification for Denial-of-Service Attacks

Traditional Denial-of-Service (DoS) attacks typically target individual systems and rely on sustained traffic injection to cause disruption. In this work, we present a cross-protocol attack in IPv4/IPv6 networks that exploits three protocol mechanisms—QUIC Version Negotiation, DNS TXT records, and IP fragmentation—to c...
