Microsoft has recorded CVE-2026-20820 — a heap‑based buffer overflow in the Windows Common Log File System driver (clfs.sys) that Microsoft classifies as an elevation of privilege vulnerability; an authorized local attacker able to run code as a standard user or manipulate CLFS‑read inputs can...

Microsoft’s Security Update Guide appears to reference CVE‑2026‑20815 for an elevation of privilege in the Capability Access Management Service (camsvc), but as of this writing the public technical record for CVE‑2026‑20815 cannot be corroborated in major third‑party vulnerability trackers or...

Microsoft's security advisory for CVE-2026-20808 confirms a race-condition vulnerability in Windows File Explorer’s printer-related code — the Printer Association Object — that can allow an authorized local user or local malware to escalate privileges on an affected system, and administrators...

Microsoft has recorded a Desktop Window Manager (DWM) information‑disclosure vulnerability under the identifier CVE‑2026‑20805; the vendor advisory classifies the issue as an information disclosure that can allow an authorized local actor to read sensitive information on a vulnerable host, and...

Microsoft’s Security Update Guide lists CVE-2026-20810 as a vulnerability in the Windows Ancillary Function Driver for WinSock (afd.sys) where the driver “frees memory not on the heap,” allowing an authorized local attacker to elevate privileges on an affected system—an escalation that can turn...

Microsoft has added a host-based integrity check to the Common Log File System (CLFS) driver that attaches HMACs to Base Log Files (.blf) and container files, validates those authentication codes on open, and—after a 90‑day learning period—refuses to parse logfiles that lack valid...

I stopped typing passwords the day I clipped a hardware security key to my keyring—and the change was seismic. A one-inch device the size of a thumb drive now does the heavy lifting of my account security: plug it into a USB port or tap it over NFC, touch the metal contact, and cryptographic...

A newly published proof‑of‑concept (PoC) called EDRStartupHinder demonstrates a local, pre‑boot startup technique that can prevent antivirus and EDR agents from initializing on Windows 11 25H2 by abusing the platform’s Bindlink API and the interaction between DLL loading and Protected Process...

Midcontinent Independent System Operator (MISO) has announced a strategic collaboration with Microsoft to build a cloud‑native, AI‑enabled unified data platform intended to accelerate transmission planning, improve real‑time situational awareness, and help the Midwest grid absorb surging...

Microsoft’s formal end-of-support for Windows 10 has turned what was already a long-running upgrade debate into a moment of real urgency — and a flurry of steep Windows 11 Pro discounts and third‑party “lifetime” license offers has followed, pitching sub‑$10 keys as a low‑cost bulletproofing...

Lock Down Your PC: Enable Windows Defender Tamper Protection + Security Baselines Difficulty: Intermediate | Time Required: 15 minutes Windows Security (Microsoft Defender) is solid out of the box—but a lot of real-world infections and “cleanup tool” damage happens after someone (or something)...

Microsoft has added a defensive integrity check to the Common Log File System (CLFS) driver: CLFS now attaches a hash‑based message authentication code (HMAC) to each Base Log File (.blf) and its containers, validates that HMAC before parsing, and will refuse to open any logfile whose...

The week’s vulnerability roundup from Cyble landed as a blunt reminder that 2026 opened with a sustained, high-pressure tempo for defenders: 678 newly tracked CVEs, nearly 100 with public Proof‑of‑Concept (PoC) code, and multiple high‑impact items already flagged by national authorities — a...

Microsoft's long-standing advice that Windows users should change their passwords every few months has finally been consigned to history — and not a moment too soon. In a revision to the Windows security baselines tied to the Windows 10 v1903 / Windows Server v1903 updates, Microsoft removed the...

Microsoft’s Work Folders documentation makes a short but important point that trips up administrators and power users alike: some folders on a Windows PC simply cannot host Work Folders because they are reserved by the operating system or are already protected by file encryption. The official...

On October 14, 2025 Microsoft formally ended mainstream security updates for Windows 10, leaving millions of otherwise serviceable PCs exposed to future vulnerabilities — but you do not have to treat that as an inevitable decline into insecurity. With a carefully chosen set of free tools and a...

The year 2025 was the moment artificial intelligence stopped being a mostly academic curiosity and became an industrial force that reshaped national policy, energy grids, markets and everyday work — and the reverberations will define the debates and decisions of 2026 and beyond. Background By...

2025 closed as the year artificial intelligence stopped being a promising feature and became a piece of industrial infrastructure that reshaped power grids, corporate budgets, national security planning, and everyday Windows‑centric IT operations. This shift was not a single event but a string...

Microsoft has quietly reworked BitLocker so that, on qualifying Windows 11 PCs, full‑disk encryption no longer has to be a heavy CPU chore — bulk AES/XTS operations can be routed into a dedicated crypto engine inside the SoC and the volume encryption key can be generated, wrapped and used...

Chinese state‑linked operators have quietly upgraded the ToneShell backdoor with kernel‑level stealth, delivering it through a signed Windows mini‑filter driver that can blind endpoint defenses and entrench espionage footholds inside government networks across Asia. Background Researchers...
