DNS-Poisoning-Triage-Lab
DNS 및 ARP 트래픽 분류 실습 Arch Linux 워크스테이션에서 수행한 교육용 패킷 분석 및 리졸버 강화 실습입니다. 범위: 이 저장소는 학습 프로젝트입니다. 포함된 캡처는 DNS 및 ARP 검사 연습에 유용하지만, 그 자체로 실시간 캐시 중독 공격, 악성 하드웨어, 특정 CVE 악용, 또는 NetworkManager 라우팅 메트릭과의 인과 관계를 증명하지는 않습니다. 이 프로젝트를 개정한 이유 첫 번째 작성물에서는 여러 관찰 결과를 확정된 원인으로 취급했습니다. 그건 지나친 주장이었습니다.

OESA-2026-3434 unbound security update
Unbound is a validating, recursive, caching DNS resolver. It is designed to be fast and lean and incorporates modern features based on open standards. To help increase online privacy, Unbound supports DNS-over-TLS which allows clients to encrypt their communication. Unbound is available for most...
CVE-2026-50046
A use-after-free flaw was found in Unbound's DNS-over-TLS DoT forwarded query handling. A remote attacker can exploit a timing error during TLS handshake failures on a server under load to trigger a daemon crash, resulting in a Denial of Service DoS. Mitigation To mitigate this issue, avoid...
