Technical overview of zero‑day exploits and Rowhammer vulnerabilities

Technical overview of zero‑day exploits and Rowhammer vulnerabilities The passage describes general cybersecurity research and known vulnerabilities (Heartbleed, Rowhammer) without linking any specific high‑profile individuals, agencies, or financial transactions to wrongdoing. It offers background context but no actionable leads for investigation. Key insights: Zero‑day exploits often become public before patches are widely deployed, creating a window for mass attacks.; Heartbleed was disclosed on April 7, 2014, after a delay that allowed widespread exploitation.; Rowhammer attacks exploit magnetic interference between memory cells to flip bits, discovered by researchers at Google in 2014‑2015.
