제목	Understanding and Mitigating Covert Channel and Side Channel Vulnerabilities Introduced by RowHammer Defenses
궁금했던 점	Do RowHammer defenses themselves create exploitable timing channels?
해본 것	LeakyHammer constructs covert/side channels from defense behavior, demonstrates website fingerprinting, and evaluates three mitigations.
당시 조건	Venue: MICRO. Year: 2025. Defense-induced refresh, throttling, or tracking alters memory timing in ways visible across protection boundaries. Verification: latest arXiv abstract/full text and official MICRO program; confidence=high.
실제 결과	workloads=two constructed channels and website-fingerprinting attack; baselines=RowHammer defenses with and without three mitigations; metrics=channel bandwidth, attack success, mitigation overhead; results=41.9 and 54.0 Kbps in latest version
왜 그랬는지	A defense can close an integrity attack while opening an information-flow channel through its observable actions.
다음에 기억할 것	Evaluate security mechanisms for timing/noninterference, not only for prevention efficacy.
언제 맞는지	DRAM systems deploying stateful or throttling-based RowHammer defenses. Limits: Channel feasibility and mitigation overhead depend on the specific defense and platform; arXiv versions report different older rates.
신뢰도	높음

Verification: latest arXiv abstract/full text and official MICRO program; confidence=high. Canonical title: Understanding and Mitigating Covert Channel and Side Channel Vulnerabilities Introduced by RowHammer Defenses Question: Do RowHammer defenses themselves create exploitable timing channels? Context: Defense-induced refresh, throttling, or tracking alters memory timing in ways visible across protection boundaries. Method: LeakyHammer constructs covert/side channels from defense behavior, demonstrates website fingerprinting, and evaluates three mitigations. Evaluation: workloads=two constructed channels and website-fingerprinting attack; baselines=RowHammer defenses with and without three mitigations; metrics=channel bandwidth, attack success, mitigation overhead; results=41.9 and 54.0 Kbps in latest version Interpretation: A defense can close an integrity attack while opening an information-flow channel through its observable actions. Reusable lesson: Evaluate security mechanisms for timing/noninterference, not only for prevention efficacy. Applicability: DRAM systems deploying stateful or throttling-based RowHammer defenses. Limits: Channel feasibility and mitigation overhead depend on the specific defense and platform; arXiv versions report different older rates.
