What happened
A wave of high-impact security incidents and discoveries was reported: a previously unknown zero-day that reportedly defeats default Windows 11 BitLocker protections (Microsoft investigating); multiple severe Linux vulnerabilities (including CopyFail and other root-impacting flaws) with patches being issued; a monthlong supply‑chain backdoor in Daemon Tools and other supply-chain compromises affecting security firms and OSS packages (element-data) that stole credentials; emergency ASP.NET fixes for macOS/Linux; and disruptive incidents such as the Canvas outage and Ubuntu infrastructure outage
