Why Endpoint Detection and Response Is No Longer Optional

Traditional antivirus software relies on a signature-based model that compares files against a database of known malware, which limits its effectiveness against modern threats. Cybercriminals have adapted by using polymorphic malware and fileless techniques that evade detection. Endpoint Detection and Response (EDR) continuously monitors device activities, tracking process activity, network connections, and file changes to detect behavioral patterns indicative of attacks. EDR also enables rapid response actions, such as isolating affected devices and terminating malicious processes. Small and medium businesses are increasingly targeted by attackers who exploit the limitations of traditional antivirus solutions. Relying solely on antivirus software creates vulnerabilities, making it essential for organizations to incorporate EDR for enhanced security.

The Evolution of Endpoint Security: Why EDR Represents a Fundamental Shift From Traditional Antivirus

Organizations that rely on technology face evolving cyber threats that traditional antivirus software struggles to address. Traditional antivirus detects known malware through signature matching but is limited in its ability to catch new or modified threats. Modern cyberattacks utilize techniques like polymorphic malware and fileless attacks to evade detection. Endpoint Detection and Response (EDR) tools have emerged as a solution, focusing on analyzing behavior rather than matching known threats. EDR continuously monitors endpoints, collects data on system activities, and uses behavioral analysis to identify suspicious actions. This allows for real-time responses to threats, such as isolating affected devices or rolling back changes made by ransomware. EDR is essential for all organizations, including small businesses, which are often targeted by attackers. It should be part of a broader security strategy that includes traditional antivirus, regular updates, employee training, access controls, and backups. When considering EDR options, businesses should prioritize response speed, visibility, reporting capabilities, and integration with existing IT support.

Your PC can get Windows 11 Pro and seven Office apps for just $25.99

A bundle is available that includes Windows 11 Pro and Microsoft Office Professional Plus 2019 for .99, reduced from a regular price of 9. The bundle provides lifetime licenses for both software, designed for a single Windows PC, and does not require a recurring Microsoft 365 subscription. Windows 11 Pro includes features like BitLocker, Hyper-V, and Windows Sandbox, while Office Professional Plus 2019 includes Word, Excel, PowerPoint, Outlook, OneNote, Access, and Publisher. Office 2019 will no longer receive support after October 2025, and Publisher will lose support by October 2026. Windows 11 Pro requires specific hardware compatibility, including TPM 2.0, which can be checked using Microsoft's PC Health Check tool.

Windows 11 can keep thumbnails of photos you deleted. Here’s how to remove them

Windows retains thumbnails in a cache file named thumbcache_256.db, but it does not save a thumbnail of every deleted photo. Other operating systems, including macOS and Linux, also use thumbnail caching. Users can access their thumbnail cache by navigating to %LOCALAPPDATA%MicrosoftWindowsExplorer, but this will not show deleted images. Thumbnails are created only when images are displayed in Explorer’s thumbnail view. Windows allows users to clear the thumbnail cache using the Disk Cleanup tool, and there is an option to disable thumbnail caching in Windows 11 Pro and higher. The cached thumbnails do not guarantee persistence and do not represent original files. Windows also keeps records of application launches in Prefetch, maintains entries for USB devices in the USBSTOR registry key, saves Wi-Fi networks and passwords, and can keep clipboard history and recent file shortcuts.

Windows 11 can keep thumbnails of photos you deleted. Here’s how to remove them

A recent post on X claims that Windows retains a thumbnail of every deleted photo in a file named thumbcache_256.db, which has raised privacy concerns among users. While Windows does maintain a thumbnail cache for efficiency, this practice is not unique to Windows, as other operating systems like macOS, Linux, and Android also use similar systems. Users can inspect or clear their thumbnail cache by accessing specific database files in the Windows Explorer directory. The claim that Windows retains "every photo you’ve ever deleted" is misleading, as thumbnails are only created when images are viewed in thumbnail mode. Windows does not cache every file, and thumbnails must exist before they can be cached. Additionally, Windows keeps app launch records in Prefetch files for performance optimization, maintains entries for USB devices in the USBSTOR registry key, retains records of Wi-Fi networks and passwords (which are encrypted), and can keep clipboard history and recent file shortcuts. Caching previews is common across various operating systems, and Microsoft is focused on user consent and privacy as it enhances Windows 11 with AI functionalities.

What Is Happening with PostgreSQL 19?

Postgres 19 is experiencing delays in its release schedule, with Beta 4 scheduled for September 24, 2026. The development team is prioritizing quality over timelines, leading to the reversion of 53 significant features during the beta phase. Notable feature reversions include SQL Property Graph Queries, ALTER TABLE MERGE/SPLIT PARTITION(S), UPDATE/DELETE FOR PORTION OF, GROUP BY ALL, a change to default TOAST compression, nontext output formats for pg_dumpall, JSON_TABLE ON ERROR cascading, fast defaults for domains with nonvolatile constraints, logical replication database-specific snapshots, nested query tracking, and online data checksums. The majority of these reversions are due to design flaws, incorrect results, or compatibility issues. There are also at-risk features identified, including RI fast-path FK checks, REPACK / REPACK CONCURRENTLY, and Postgres_fdw statistics import. Despite these challenges, promising features such as pg_plan_advice, parallel autovacuum, ON CONFLICT DO SELECT, and logical replication enhancements are still anticipated in PG19. AI tools are being utilized in the development process to identify bugs and create test cases. Postgres 18 remains a reliable upgrade target, while features like property graphs and GROUP BY ALL are now planned for PG20.

The Fault Line Spreads: Azure’s September CVE Cluster Now Covers PostgreSQL and Billing

Two newly identified Critical CVEs have expanded Microsoft's September identity infrastructure vulnerabilities to over ten verified weaknesses across more than ten distinct services. The Azure Database for PostgreSQL is vulnerable to CVE-2026-85878, an Improper Authorization flaw (CWE-285) with a CVSS score of 9.9. Azure Billing is impacted by CVE-2026-62874, which presents an Insufficient Data Authenticity Verification issue (CWE-345) with a CVSS score of 10.0. Both vulnerabilities were disclosed on September 18 and validated by Tenable and MITRE. CVE-2026-85878 allows an authorized attacker to elevate privileges over the network with minimal complexity, while CVE-2026-62874 requires no authentication, enabling unauthenticated attackers to jeopardize financial integrity. The vulnerability cluster first emerged during the Patch Tuesday cycles on September 3 and September 8, with initial reports highlighting critical flaws in core services. Other September disclosures include CVE-2026-83711 (Azure AD B2C, CVSS 10.0), CVE-2026-70352 (Azure AI Language, CVSS 10.0), CVE-2026-83941 (Entra ID, CVSS 9.9), CVE-2026-62916 (Entra ID, CVSS 9.1), CVE-2026-69857 (Azure Cosmos DB, CVSS 8.5), and CVE-2026-69854 (Spring Cloud Azure, CVSS 9.0). Activity heightened between September 17 and 18 with the introduction of CVE-2026-77903 (Microsoft Dataverse, CVSS 9.0) and CVE-2026-69843 (Microsoft Fabric, CVSS 10.0). The attack surface has broadened from authentication concerns to encompass trust in AI endpoints, data storage locations, and billing verification processes. Seven out of the ten vulnerabilities are unauthenticated, and all issues were addressed through server-side fixes by Microsoft. The extensive range of affected services suggests these vulnerabilities indicate a shared architectural dependency on authentication logic.
