ESET’s researchers have uncovered a previously undocumented threat cluster that covertly poisons legitimate IIS-hosted websites to manipulate Google rankings while also planting a stealthy C++ backdoor on Windows servers — a campaign ESET calls GhostRedirector that, according to an internet-wide...

Thanks — I can write the 2,000+ word, in-depth feature article in rich Markdown for WindowsForum.com. Before I start, two quick clarifying questions so I match your needs exactly: 1) Do you want the article to be strictly based on Microsoft’s advisory at the MSRC link you provided, or do you...

ESET researchers have uncovered a compact but sophisticated campaign — tracked as GhostRedirector — that has compromised at least 65 Internet‑facing Windows servers and combined a native C++ backdoor with a malicious IIS native module to deliver long‑lived persistence and server‑side SEO fraud...

CISA’s latest update to the Known Exploited Vulnerabilities (KEV) Catalog adds three actively exploited flaws — a Linux kernel TOCTOU race condition, an Android Runtime issue, and a high‑impact Sitecore deserialization vulnerability — forcing organizations that track KEV and federal agencies...

CISA has added CVE-2025-57819 — an authentication‑bypass and SQL‑injection chain that can lead to remote code execution in Sangoma FreePBX — to its Known Exploited Vulnerabilities (KEV) Catalog, citing evidence of active exploitation and urging immediate remediation. Background FreePBX is a...

Security researchers have observed a coordinated, large‑scale reconnaissance campaign probing Microsoft Remote Desktop services that began as a sudden one‑day spike and escalated into a torrent of scans — a pattern that looks less like opportunistic background noise and more like deliberate...

CISA’s update on August 26, 2025, which bundles three focused Industrial Control Systems (ICS) advisories, is a timely reminder that vulnerabilities in engineering tools, PLC controllers, and system managers remain high-risk vectors for operational technology environments. The agency published...

CISA’s August 25 alert that it has added three new flaws to the Known Exploited Vulnerabilities (KEV) Catalog should be treated as a red alert for IT teams: two significant issues in Citrix Session Recording (CVE-2024-8068 and CVE-2024-8069) and a client-side Git link-following vulnerability...

This week’s wave of security headlines delivered a clear, uncomfortable message for Windows admins and security teams: the internet’s trust fabric is fraying in ways that let attackers hide inside legitimate flows — and Microsoft’s own infrastructure, link‑wrapping services, and even patch...

This week’s Cisco Talos briefing reads like a travelogue-turned-threat-advisory: after a short, evocative opening about cherry pie and Douglas firs, the post pivots sharply to an urgent security alert — a Russian state‑backed cluster Talos calls Static Tundra is actively exploiting a...

TÜV SÜD’s decision to fold Microsoft Defender and Microsoft Security Copilot into its global security operations marks a clear bet on AI-augmented defense: the German testing, inspection, and certification giant reports faster investigations, consistent reporting, and a rapid ramp-up for junior...

Security researchers have uncovered a targeted supply‑chain campaign — dubbed “Solana‑Scan” — in which malicious npm packages masquerading as Solana SDK utilities are being used to harvest developer credentials, wallet keyfiles and other high‑value artifacts from developer machines. Background /...

Microsoft’s Security Copilot arrives at a time when defenders are drowning in alerts, and the product’s promise is simple but consequential: apply generative AI to compress investigation time, automate routine triage, and translate dense telemetry into actionable decisions for security teams and...

Microsoft’s August Patch Tuesday closed a dangerous mix of high‑impact remote code execution (RCE) flaws and a publicly disclosed Kerberos elevation‑of‑privilege (EoP) vulnerability that together raise the operational urgency for domain controllers, document‑processing servers, and any service...

Microsoft’s August Patch Tuesday delivered a heavy-duty security package this month — industry tallies vary between 107 and 111 vulnerabilities, including a publicly disclosed Kerberos elevation-of-privilege issue (CVE‑2025‑53779) and roughly a dozen other critical remote‑code‑execution (RCE)...

CISA’s latest update places three long‑standing and newly discovered flaws squarely in the crosshairs of enterprise defenders, adding CVE‑2013‑3893 (Internet Explorer), CVE‑2007‑0671 (Microsoft Excel), and CVE‑2025‑8088 (WinRAR) to the agency’s Known Exploited Vulnerabilities (KEV) Catalog on...

The identifier CVE-2025-49712 does not appear in any public, authoritative advisory or vulnerability database at this time; the single URL you supplied resolves to Microsoft’s update guide infrastructure but returns no accessible content without JavaScript, and independent searches for...
