September Windows Server updates break Remote Desktop Services

September 2026 Windows Server cumulative updates cause Remote Desktop Services failures on Server 2019, 2022 and 2025, forcing some admins to roll back.

Admins report Remote Desktop Services failures after installing September 2026 Patch Tuesday updates KB5122876 (Server 2019), KB5122882 (Server 2022), and KB5122871 (Server 2025), with connections hanging, sessions failing after logout, and some systems requiring hard resets. One administrator debugging Server 2022 observed an apparent deadlock between RDP and the Local Session Manager, though Microsoft has not confirmed a root cause. Rolling back the updates restores RDS functionality but removes this month's security fixes. Microsoft had not responded to inquiries at publication time.

Microsoft Excel KB5002914 update breaks copy and paste for some users

Microsoft's September Patch Tuesday update KB5002914 breaks copy-and-paste and formula dragging in Excel 2016 through 2024; uninstalling the update restores functionality.

Users on Reddit and Microsoft Q&A report that the KB5002914 security update shipped in the September 2026 Patch Tuesday breaks copy-and-paste, autofill, and formula dragging in Excel. The problem spans Office 2016 through 2024 across MSI and Click-to-Run installations, including Office LTSC Standard 2021, with some teams blocked after widespread patching. Uninstalling KB5002914 or downgrading the Office build restores functionality, though replacing the excel.exe binary is not recommended. BleepingComputer could not reproduce the issue on Excel 2019 Version 2508 Build 19127.20302 and contacted Microsoft for comment.

Trezor warns users of email provider breach, phishing attacks

Trezor says attackers breached its third-party email provider and are phishing customers with fake STM32 entropy vulnerability alerts.

Trezor warned customers that threat actors breached its third-party email provider and sent fake 'Critical Security Alert: STM32 Entropy Vulnerability' emails from [email protected], claiming wallet seeds were exposed to brute-force attacks; the phishing domain has been taken down while Trezor investigates. This follows the ShipMonk breach, revised upward from about 14,000 to 81,000 customers (including 67,000 additional US customers) who received orders between May 10 and August 8, 2026. Attackers reportedly exploited a Metabase SQL injection zero-day to access ShipMonk data, and ShinyHunters sent extortion emails.

ShinyHunters claims it stole 284 million patient records from McKesson

ShinyHunters claims theft of 284 million patient records from McKesson via vishing, Okta takeover, and Salesforce/Snowflake access, demanding $55,236,150.

McKesson disclosed in an SEC filing a cybersecurity incident detected August 25, 2026, involving unauthorized access to third-party applications and data exfiltration affecting a subset of customers in its Oncology & Multispecialty and Medical-Surgical business units. ShinyHunters told BleepingComputer it entered through vishing calls to employees, used stolen credentials to take over Okta single sign-on accounts, and extracted about a terabyte of data from Salesforce and Snowflake environments over four days. The group claims 284 million database rows including names, addresses, Social Security numbers, Medicaid details, medical record numbers, and medication data, and demanded $55,236,150 with a 72-hour deadline; none of these claims have been independently verified.

    Unauthenticated Double-Free RCE in Microsoft Windows IKE Extension
    A double-free memory-corruption flaw (CWE-415) in the Microsoft Windows Internet Key Exchange (IKE) service extension allows a remote, unauthenticated attacker to trigger the bug with crafted network traffic, with no privileges or user interaction required. Successful exploitation yields remote code execution with full system impact, reflected in the critical 9.8 CVSS score (high confidentiality, integrity, and availability). The vulnerable IKE component is present in Windows 10 (1607, 1809, 21H2, 22H2), Windows 11 (23H2, 24H2, 25H2, 26H1), and Windows Server 2016, 2019, and 2022 (including 23H2), which ship it as a built-in feature. CISA added the flaw to the Known Exploited Vulnerabilities catalog on 2026-08-18, and security reporting confirms it is being actively exploited in the wild, though ransomware use is not yet confirmed. No public proof-of-concept is known, but the high EPSS score (72.7%, 99th percentile) signals a very strong likelihood of imminent or ongoing exploitation.
