The Cloudflare Outage May Be a Security Roadmap (Krebs on Security)

Actualités
An intermittent outage at Cloudflare on Tuesday briefly knocked many of the Internet’s top destinations offline. Some affected Cloudflare customers were able to pivot away from the platform temporarily so that visitors could still access their websites. But security experts say doing so may have also triggered an impromptu network penetration test for organizations that have come to rely on Cloudflare to block many types of abusive and malicious traffic. At around 6:30 EST/11:30 UTC on Nov. 18, Cloudflare’s status page acknowledged the company was experiencing “an internal service degradation.” After several hours of Cloudflare services coming back up and failing again, many websites behind Cloudflare found they could not migrate away from using the company’s services because the Cloudflare portal was unreachable and/or because they also were getting their…

Microsoft Patch Tuesday, November 2025 Edition (Krebs on Security)

Sécurité
Microsoft this week pushed security updates to fix more than 60 vulnerabilities in its Windows operating systems and supported software, including at least one zero-day bug that is already being exploited. Microsoft also fixed a glitch that prevented some Windows 10 users from taking advantage of an extra year of security updates, which is nice because the zero-day flaw and other critical weaknesses affect all versions of Windows, including Windows 10. Affected products this month include the Windows OS, Office, SharePoint, SQL Server, Visual Studio, GitHub Copilot, and Azure Monitor Agent. The zero-day threat concerns a memory corruption bug deep in the Windows innards called CVE-2025-62215. Despite the flaw’s zero-day status, Microsoft has assigned it an “important” rating rather than critical, because exploiting it requires an attacker to already have…
