Ransomware & ExtortionMicrosoft Removes Reinstallation Requirement for Enabling Smart App Control in Windows 11
Microsoft has eliminated the primary restriction on Smart App Control, allowing home users to activate or reactivate the Windows 11 security feature without performing a clean installation of the operating system. Previously, toggling the setting effectively required users to reinstall the entire system. Smart App Control leverages Microsoft's cloud-based reputation system and analyzes digital signatures to block suspicious, potentially dangerous, or unsigned files before execution. The toggle is now accessible through Windows Security under App & browser control. The update is being rolled out gradually via Windows 11 updates, though users who have disabled optional diagnostic data may still need a reset or reinstallation. The feature can interfere with developers and enterprise users working with rare or unsigned tools, as there is no option to whitelist individual blocked applications.
Microsoft Releases Fix for Windows Defender Crashes During Quick and Full Scans
Microsoft has issued a security intelligence update to resolve a crash in Windows Defender that occurred during quick or full system scans on affected Windows 10 and Windows 11 devices. The bug, introduced after a recent set of patches, caused the antivirus service to terminate unexpectedly with the message "Threat service has stopped. Restart it" and access violation error 0xc0000005. Some users misinterpreted the repeated failures as malware infection or severe system damage, leading them to reinstall Windows entirely. Administrators were able to reproduce the issue consistently across multiple machines simply by initiating a quick scan, confirming the root cause lay in Defender itself rather than individual endpoints. The fix is included in security intelligence version 1.457.236.0 and all subsequent releases, with Microsoft advising users to ensure automatic updates are applied via Windows Update or manually through the Windows Security interface.
Microsoft Removes WMIC from Windows 11 After Years of Abuse as LOLBIN by Ransomware and Attackers
Microsoft has begun permanently removing the legacy WMIC command-line utility from Windows 11, starting with versions 24H2 and 25H2. The tool is no longer available in fresh installations, has been dropped as an optional component, and is absent from the latest beta builds. WMIC provided text-based access to Windows Management Instrumentation for querying hardware, processes, services, and security software, as well as performing administrative tasks. Although the underlying WMI technology remains untouched, Microsoft has deprecated the command shell due to its long-standing use as a LOLBIN in cyberattacks. Ransomware operators have leveraged WMIC to delete shadow copies and hinder recovery, while other attackers used it to enumerate and disable security tools or add exclusions in Microsoft Defender. Administrators are directed to migrate to PowerShell, COM API, .NET libraries, and modern scripting languages, which will require rewriting legacy automation scripts.
Cybercriminals Deploy Advanced AI for Continuous Automated Reconnaissance and Exploitation at Scale
Advanced AI models now enable cybercriminal groups to maintain uninterrupted reconnaissance across enterprises in every sector, mapping domains, exposed services, and infrastructure changes at a pace no human team could sustain for weeks. The automated process targets two opposite profiles of vulnerable systems: legacy environments left unpatched for years with outdated versions and forgotten permissions, and rapidly deployed applications built through Vibe Coding that reach production without security review. The entire attack chain—reconnaissance, vulnerability identification, validation, and exploitation—is now executed by AI agents operating with minimal human oversight. What previously required a dedicated specialized team focused on one target at a time now runs in parallel against thousands of targets simultaneously, with marginal cost approaching zero for each additional attack. This collapse in operational costs and rise in success rates has restructured the cybercrime economy, funding increasingly sophisticated tools and lowering the barrier for new operators who need only platform access rather than deep technical expertise. The time window between an application reaching production and discovery by attackers has shrunk to hours, while most organizations still treat security as a finite project rather than an ongoing process.
GitHub Experiences Major Global Outage Affecting API, Actions, Copilot and Multiple Core Services
On August 17, GitHub suffered a widespread outage that impacted nearly all major platform functions including the web interface, API, Issues, Pull Requests, Actions, Webhooks, Pages, Git Operations, and Copilot. Approximately 20% of requests to the site and API failed during peak impact, with archive and raw repository content loads reaching around 50% error rates. Corporate authentication mechanisms such as SAML and OIDC, along with SCIM and Team Sync services, were also disrupted while Codespaces remained operational. The incident began around 13:40 UTC with progressive degradation across components, prompting GitHub to identify and mitigate the root cause. Services are gradually recovering but error rates remain slightly elevated, and the incident has not yet been fully closed. Parallel issues were reported in other Microsoft services including Teams and Copilot, with unconfirmed speculation linking the event to Amazon Web Services network problems.

Microsoft Patches Seven Exchange Server Vulnerabilities Including Critical Remote Code Execution Flaw
Microsoft has addressed seven vulnerabilities in Exchange Server that enable remote code execution, privilege escalation, denial of service, content spoofing, and security feature bypass. The most severe issue, CVE-2026-62913, carries a CVSS score of 8.8 and involves a heap buffer overflow that can be exploited remotely by a low-privileged attacker without any user interaction. Successful exploitation grants code execution on the server, facilitating email theft, persistence mechanisms, lateral movement, and ransomware deployment. CVE-2026-62911, demonstrated at Pwn2Own Berlin with a CVSS score of 8.0, allows authentication bypass through capture and replay of credentials. Additional fixes cover SSRF-based privilege escalation, remote deserialization crashes, content spoofing, and authorization bypasses. Patches are available for Exchange Server Subscription Edition, while 2016 and 2019 versions receive updates only through the Extended Security Update program.
Windscribe Releases Open-Source PowerShell Script to Remove Microsoft's Persistent Global Device Identifier from Windows
Windscribe has published an open-source PowerShell script called deGDID that removes Microsoft's Global Device Identifier (GDID) from Windows systems and prevents the creation of new identifiers. The persistent tracker survives IP address changes and operates below the VPN layer, allowing Microsoft to maintain device tracking even when users employ privacy tools. The script was developed after the FBI used GDID to identify a suspected hacker, raising concerns about undisclosed device fingerprinting. deGDID modifies registry access control lists and blocks the DeviceAdd interface to stop Windows from regenerating the identifiers after reboots or server contacts. While effective at disabling the tracking mechanism, the tool can break authentication to login.live.com and disrupt certain Microsoft cloud services. It is intended only for unmanaged consumer devices and will not run on domain-joined or corporate-managed systems. The project is described as experimental and cannot delete identifiers already transmitted to Microsoft servers.
Dangerous C++ Traps: Memory Safety Issues, Undefined Behavior, and Code That Betrays Developers
Around 70% of vulnerabilities assigned CVE numbers by Microsoft each year stem from memory safety errors, with Chromium reporting a similar pattern for serious Chrome bugs. The article examines how C++ deliberately permits low-level memory access for performance but demands strict discipline to avoid undefined behavior (UB). It details real-world cases including Heartbleed (CVE-2014-0160) in OpenSSL, use-after-free errors, buffer overflows, and data races. Modern tools such as AddressSanitizer, UndefinedBehaviorSanitizer, and ThreadSanitizer are presented as essential for detection, alongside recommendations for RAII, std::span, and smart pointers. The piece also discusses C++26 changes introducing erroneous behavior for uninitialized variables and advises when to consider memory-safe languages like Rust for new components. Practical migration steps and compiler warning strategies are outlined to reduce risk in existing codebases.
Microsoft Tightens Corporate Windows Activation with TPM-Bound KMS Servers
Microsoft is strengthening its corporate Windows licensing controls by introducing new requirements for KMS servers used in volume activation. The changes will bind KMS hosts to TPM hardware attestation, preventing cloned or fake servers from issuing licenses to unlicensed devices. Warnings will begin appearing in Windows Server 2025 in August 2026, with mandatory enforcement planned for the next LTSC release. Existing KMS systems will continue operating normally until the new rules take effect. The update targets enterprise environments with on-premises KMS infrastructure and does not affect individual consumer devices or common non-KMS activation bypass methods. Administrators can already verify TPM support on physical servers using the Get-TpmSupportedFeature command.
GitHub Removes 10,000 Malware Repositories After Public Exposure but Takes No Further Action
An investigation reveals that GitHub hosts thousands of repositories distributing trojanized ZIP archives, many of which have persisted for two years despite the platform's resources. The malicious repositories follow consistent patterns in README files, including specific headings and links to versioned archives hosted on githubusercontent.com. A detailed article and accompanying script published on Hacker News identified over 10,000 such repositories, prompting GitHub to delete only those specific entries. New repositories matching the same patterns continue to appear and remain active, with no additional proactive measures taken by the security team. The situation highlights questions about Microsoft's approach to automated detection and response on its subsidiary platform.
Microsoft Adds Option to Completely Disable Copilot Key in Windows 11
Microsoft is testing a new setting in experimental builds of Windows 11 that lets home users fully disable the dedicated Copilot key on compatible keyboards. The option, labeled Do nothing, appears in the Bluetooth and devices section under Keyboard settings and allows users to reassign the key away from launching the AI assistant. Enthusiast phantomofearth discovered the feature, which currently sits alongside choices for launching Microsoft 365 Copilot, performing a search, or executing a custom action. The rollout is gradual, with some Windows Insiders receiving the setting earlier than others. The Copilot key was introduced on new Windows laptops in 2024 as a replacement for the right Ctrl key to highlight AI PCs. Earlier this year Microsoft had already promised limited support for restoring the original Ctrl function, while users previously relied on third-party tools such as NoCopilotKey to prevent accidental activation.
LG Monitors Automatically Install McAfee App via Windows Update Without User Consent
Home users of Microsoft Windows have discovered that certain LG monitors automatically install companion software upon connection to a PC, followed by prompts to try a trial version of McAfee antivirus. The installation occurs through the standard Windows driver and software delivery mechanism without providing a clear, separate confirmation dialog. The LG Monitor App Installer requests broad access to system resources, raising concerns even though the application itself is not classified as malicious. YouTube channel Gamers Nexus identified the behavior across both new monitors and models released approximately three years ago, including units previously used in office environments. Manufacturers commonly supply utilities for display calibration, firmware updates, and monitor management, yet the process becomes problematic when it serves as an entry point for optional software and advertising. Users are advised to review installed applications and remove unnecessary LG utilities, while organizations should monitor automatic software deployment after connecting peripherals. Neither LG nor Microsoft has commented on the issue at the time of publication.
CISA Adds Three Exploited Vulnerabilities in FortiSandbox and SharePoint to KEV Catalog
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added three actively exploited vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalog on July 16, 2026. Two of the flaws affect Fortinet’s FortiSandbox malware analysis product and involve OS command injection issues that can be triggered via specially crafted HTTP requests without requiring authentication. The third vulnerability impacts Microsoft SharePoint and stems from unsafe deserialization of untrusted data, potentially allowing remote code execution over the network. CISA’s action follows public advisories released by the vendors in April and June 2026. The agency is urging organizations to apply available patches and mitigations immediately to reduce the risk of compromise.
CISA Urges Immediate Patching as Multiple SharePoint Server Vulnerabilities Confirmed Exploited
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued an urgent advisory after confirming active exploitation of multiple vulnerabilities in Microsoft SharePoint Server. Four specific CVEs have been added to the Known Exploited Vulnerabilities (KEV) catalog, with one additional flaw flagged by Microsoft as high-risk even without confirmed exploitation. Successful attacks can lead to remote code execution, theft of Internet Information Services (IIS) machine keys, establishment of persistent access, and deployment of malware. CISA recommends applying the latest Microsoft patches immediately, verifying successful installation, enabling the Antimalware Scan Interface (AMSI), and strengthening monitoring through Microsoft Defender Antivirus. Organizations are also advised to avoid direct internet exposure of SharePoint servers and to implement Layer 7 reverse proxies with enhanced logging to reduce the attack surface.
Eleven Old Microsoft-Signed UEFI Shims Enable Bypass of Secure Boot on Linux Systems Still Trusting Microsoft Corporation UEFI CA 2011
Eleven legacy UEFI shim bootloaders signed by Microsoft, all version 0.9 or earlier, can be abused to bypass UEFI Secure Boot on systems whose firmware still trusts the Microsoft Corporation UEFI CA 2011 certificate. Attackers who manage to place one of these vulnerable shims in the boot path can execute arbitrary code before the operating system loads, enabling bootkits, persistence, and kernel-level compromise with minimal visibility to traditional EDR tools. The issue stems not from a new kernel bug but from the continued validity of old, correctly signed binaries that have not yet been revoked in the DBX database. Microsoft has already issued DBX revocation updates, yet administrators must first upgrade shim, GRUB, and other boot components to modern versions that support SBAT before applying the revocations to avoid bricking systems. Affected implementations include Red Hat Enterprise Linux 7.2, CentOS 7.2, Oracle Linux 7.2, openSUSE, baramundi Management Suite up to 2024R1, WipeDrive 8.0.0–8.1.3, PC Doctor Service Center, and Abitti 1. The problem is tracked under CVE-2026-8863 and CVE-2026-10797, with public references available from The Hacker News, CERT/CC VU#616257, NIST NVD, and Help Net Security.
Microsoft Pauses Windows Security Update KB5101650 After It Triggers Shutdowns and Overheating on Dell Laptops with Intel Processors
A mandatory July security update intended to patch 570 vulnerabilities in Windows instead caused spontaneous shutdowns, performance drops, overheating, and rapid battery drain on certain Dell laptops equipped with Intel processors. The root cause was traced to incompatibility between the new Windows USB-C Connection Manager interface and Intel’s Innovation Platform Framework Processor Participant driver, which manages CPU power consumption and thermal control. Microsoft had already observed early signs of the conflict in June with the optional update KB5095093, but the problematic driver changes were carried forward into the mandatory Patch Tuesday release. Because the exact list of affected Dell models was not disclosed, the full scope of the issue remains difficult to assess, though the company acted quickly to block rollout on incompatible hardware. No widespread hardware damage has been reported, and Microsoft is working with Intel and Dell to deliver a fix in the coming days while continuing to recommend the update for unaffected systems.
Microsoft Permanently Locks Hacked Account After Security Changes, Erasing 25 Years of OneDrive Data and Purchases
A streamer named Joshua Kane lost access to his Microsoft account containing 25 years of digital files, family photos, and purchased content after it was compromised by an attacker who altered security settings. Microsoft confirmed the account belonged to him and had been breached but refused to restore access, citing internal policies that prevent manual recovery once security information is changed by an unauthorized party. The company stated that OneDrive content cannot be extracted due to its encryption architecture and privacy protections, leaving the data permanently inaccessible even to Microsoft engineers. Kane was advised to create a new account and repurchase games and services, while the incident quickly gained over two million views on social media and prompted other users to share similar experiences. The case underscores the risks of insufficient account protection and the permanent consequences of account takeovers when two-factor authentication and backup strategies are not properly implemented.
Secure Boot Bypassed for Over a Decade Through Unrevoked Vulnerable Shim Bootloaders, ESET Finds
ESET researchers have disclosed that Secure Boot, the UEFI mechanism designed to block malicious code before Windows or Linux starts, could be bypassed for more than ten years using old but still-trusted shim bootloader images signed by Microsoft. The 11 vulnerable shims, some dating back to 2013, were never added to revocation lists despite known vulnerabilities, allowing attackers to load unsigned or malicious code early in the boot process. The flaw affected both Linux distributions and Windows systems because UEFI firmware does not tie a Microsoft-signed shim to a specific operating system. After Microsoft finally revoked the images in its June updates following ESET’s disclosure, users were advised to check firmware policies and Linux Vendor Firmware Service for proper propagation of the new revocation data. The incident highlights systemic weaknesses in managing thousands of signed boot components and the central trust role played by Microsoft in the UEFI ecosystem.
Microsoft Patches Record 570 Windows Vulnerabilities in July Update, Including Three Actively Exploited Zero-Days
Microsoft released its largest Patch Tuesday update to date, addressing 570 vulnerabilities across Windows and related products. Among them are three zero-day flaws, two of which have already been exploited in real-world attacks. Fifty-nine issues were rated critical, with 48 enabling remote code execution. The company credited its use of AI for discovering more vulnerabilities in the Windows codebase. The update covers a wide range of components including .NET, Active Directory services, Microsoft Office, Azure services, and Microsoft Defender. Administrators are urged to apply the patches promptly to mitigate risks from privilege escalation, remote code execution, and information disclosure flaws.
Hidden Spy for 1.6 Million Users: Popular Browser Extension ModHeader Secretly Collected Browsing History
Google and Microsoft have removed the popular ModHeader browser extension from the Chrome Web Store and Microsoft Edge Add-ons after security researchers discovered a hidden mechanism designed to secretly collect users' browsing history. The extension, which had approximately 1.6 million installations, allowed developers to modify HTTP headers for testing and debugging purposes but contained a dormant data-collection module in its legitimate codebase. British firm Stripe OLT confirmed that the suspicious code was part of the genuine signed build rather than a fake version. Although the history-stealing functionality remained inactive due to an empty internal browser list, the extension still transmitted telemetry data and could have been activated remotely via a simple update. Experts recommend immediate removal of the extension, replacement of any credentials entered through it, and blocking of the domains stanfordstudies[.]com and extensions-hub[.]com.
Windows Defender Patch for RoguePlanet Zero-Day Vulnerability May Exhaust Disk Space on Windows Systems
Microsoft released a security update addressing the RoguePlanet zero-day vulnerability (CVE-2026-50656) in the Microsoft Malware Protection Engine used by Windows Defender. The flaw, disclosed earlier by researcher NightmareEclipse, allowed remote attackers to gain administrative control over Windows 10 and Windows 11 even when real-time protection was disabled. While the patch was intended to resolve the issue and deploy automatically, the researcher now claims it introduces a new problem involving excessive disk writes. Specifically, the update may cause Defender to cache extremely large Zone.Identifier alternate data streams without size limits, potentially filling the entire drive. The attack vector involves a malicious SMB server that serves oversized metadata streams while maintaining the connection. Microsoft has not yet confirmed the reported behavior, and tensions between the company and the researcher continue over disclosure practices and bug bounty rewards.
Windows Tracks Users Through Persistent GDID Identifier: How to Minimize Your Digital Footprint
A recent case involving a 19-year-old hacker identified through his Windows installation has highlighted how Microsoft’s GDID creates a permanent device fingerprint that survives VPNs and IP changes. GDID serves as a constant identifier across licensing, Microsoft Store, telemetry, and other services, making it difficult for users to stay anonymous even when changing networks. While there is no single button to disable this functionality completely, several practical steps can significantly reduce the amount of data Windows sends to Microsoft. These include switching to a local account instead of a Microsoft Account, disabling activity history, limiting optional diagnostic data, and turning off unused background services such as Phone Link and cloud synchronization. Experts note that simply reinstalling Windows does not erase the link if the same Microsoft Account is used afterward. The story underscores the ongoing trade-off between privacy and convenience in the Windows ecosystem.
