🔔 Microsoft’s September 2025 update addresses 84 vulnerabilities, including two publicly disclosed zero-days and eight Critical issues. CrowdStrike’s analysis identifies elevation of privilege, remote code execution and information disclosure as the top exploitation vectors and notes many critical flaws require some user interaction. Key affected components include Windows, Extended Security Updates (ESU) and Microsoft Office, with notable CVEs in SMB, NTLM, Hyper-V and graphics subsystems. Organizations should prioritize patching, apply mitigations for unpatchable issues, and plan for Windows 10 end of support in October 2025.

⚠️ Microsoft says the August 2025 security updates are causing unexpected User Account Control (UAC) credential prompts and preventing application installations and MSI repair operations for non‑admin users across supported Windows client and server releases. The behavior stems from a patch addressing CVE-2025-50173, a Windows Installer privilege escalation vulnerability that now enforces elevated UAC prompts during MSI repair and related operations. Affected scenarios include MSI repair commands, ConfigMgr deployments relying on per‑user advertising, Secure Desktop enablement, and launching certain Autodesk applications. Microsoft plans a fix allowing admins to exempt specific apps and recommends running affected apps as administrator or applying a Known Issue Rollback via support as a temporary mitigation.

🔒 Google has released its September 2025 Android security updates addressing 120 vulnerabilities, including two issues that Google says have been exploited in limited, targeted attacks. The two highlighted flaws are CVE-2025-38352 (CVSS 7.4), affecting the Linux Kernel, and CVE-2025-48543, impacting the Android Runtime; both can enable local privilege escalation with no user interaction. Google issued patch levels 2025-09-01 and 2025-09-05 to let partners deploy common fixes more quickly and credited Benoît Sevens of TAG with reporting the kernel issue.

🚨 Check Point attributes a BYOVD campaign to the Silver Fox actor that leverages a Microsoft-signed WatchDog kernel driver (amsdk.sys v1.0.600) to neutralize endpoint defenses. The operation uses a dual-driver approach—an older Zemana-based driver on Windows 7 and the WatchDog driver on Windows 10/11—to terminate processes and escalate privileges. An all-in-one loader bundles anti-analysis checks, embedded drivers, AV-killer logic, and a ValleyRAT downloader to establish persistent remote access.

⚠️ GE Vernova's CIMPLICITY HMI/SCADA software is affected by an Uncontrolled Search Path Element vulnerability (CVE-2025-7719) in versions 2024, 2023, 2022, and 11.0. CISA reports this flaw could enable a low-privileged local attacker to escalate privileges; a CVSS v4 score of 7.0 and a CVSS v3.1 score of 7.8 were calculated. The issue is not remotely exploitable and no public exploitation has been reported; GE Vernova recommends upgrading to CIMPLICITY 2024 SIM 4 and following the Secure Deployment Guide while CISA advises network isolation and secure remote access.

⚠ Schneider Electric disclosed an improper privilege management vulnerability (CVE-2025-8453, CVSS 6.7) affecting Saitel DR and Saitel DP Remote Terminal Units that could allow an authenticated privileged engineer with console access to escalate privileges and potentially execute arbitrary code. Schneider released HUe firmware 11.06.30 for Saitel DR to remediate the issue; a remediation plan for Saitel DP is pending. CISA notes the vulnerability is not remotely exploitable and recommends limiting physical and console access, enforcing root ownership and restrictive permissions on configuration files, and following ICS defensive guidance.

🚨 Microsoft Threat Intelligence says financially motivated group Storm-0501 has refined a brutal hybrid ransomware chain that leverages hijacked privileged accounts to pivot from on‑prem Active Directory into Azure, exploiting visibility gaps to exfiltrate, encrypt, and mass‑delete cloud resources and backups. The actor used Evil‑WinRM for lateral movement and DCSync to harvest credentials, abused a non‑MFA synced global admin to reset passwords, and created a malicious federated domain for broad persistence. After exfiltration they deleted backups where possible, encrypted remaining cloud data, and initiated extortion via a compromised Microsoft Teams account. CISOs are urged to enforce least privilege, audit on‑prem assets, close cloud visibility gaps, and rehearse ransomware playbooks.

🔒 FUJIFILM Healthcare Americas Corporation has released fixes for a privilege-escalation vulnerability (CVE-2025-54551) affecting Synapse Mobility. The issue is an external control of an assumed-immutable web parameter that can be abused remotely with low attack complexity; CVSS v4 score is 5.3. FUJIFILM recommends upgrading to 8.2 or applying patches for 8.0–8.1.1. Immediate mitigations include disabling the configurator search function or unchecking "Allow plain text accession number," and CISA advises minimizing network exposure and using secure remote access.

🔬 Google researchers demonstrated practical improvements to the Retbleed speculative-execution attack, showing that on AMD Zen 2 CPUs attackers can read arbitrary RAM at roughly 13 KB/s with perfect cache-extraction accuracy. They adapted a modified Speculative ROP technique to evade Spectre v2 mitigations and showed ways to bypass Linux kernel defenses. The exploit still requires prior knowledge of kernel configuration, but common default builds and probing reduce that hurdle, and Google has already restricted Zen 2 in certain cloud workloads.

🔒 Siemens has disclosed a Least Privilege Violation in the Wibu CodeMeter runtime that affects the Desigo CC product family and SENTRON Powermanager series. The issue (CVE-2025-47809) can allow local privilege escalation immediately after installation if the CodeMeter Control Center is present and not restarted. A CVSS v3.1 base score of 8.2 has been assigned. Siemens and WIBU recommend updating to CodeMeter v8.30a and restarting systems; CISA advises network segmentation and minimizing exposure.

🔍 Microsoft Threat Intelligence details PipeMagic, a modular backdoor used by Storm-2460 that masquerades as an open-source ChatGPT Desktop Application. The malware is deployed via an in-memory MSBuild dropper and leverages named pipes and doubly linked lists to stage, self-update, and execute encrypted payload modules delivered from a TCP C2. Analysts observed exploitation of CVE-2025-29824 for privilege escalation followed by ransomware deployment, with victims across IT, finance, and real estate in multiple regions. The report includes selected IoCs, Defender detections, and mitigation guidance to help defenders detect and respond.
