Attackers are actively targeting Windows 10/11 and various Windows server versions, exploiting vulnerabilities that allow them to gain system privileges. Administrators are advised to ensure that Windows Updates are enabled and systems are updated promptly.
One notable vulnerability, designated as CVE-2025-29824, impacts the protocol file system driver. Currently classified as "high," this vulnerability allows locally authenticated attackers to escalate their permissions. It is characterized as a memory corruption issue, implying that attackers can exploit it with specific inputs. If attackers succeed, they can execute arbitrary malicious code, putting entire systems at risk. Microsoft has yet to release patches for Windows 10 (both 32-bit and 64-bit), and a timeline for these updates remains uncertain.
Furthermore, Microsoft has identified several "critical" malware vulnerabilities. These include threats associated with Excel (CVE-2025-27752), Hyper-V (CVE-2025-27491), and Windows Remote Desktop Services (CVE-2025-27480). Particularly with Remote Desktop Services, an attacker needs to connect to a vulnerable system via RDP and execute a race condition to deploy malicious code. Patches for Hyper-V on Windows 10 are also pending.
Additional security updates have been rolled out for Office, SharePoint, and Windows Defender. These vulnerabilities can facilitate unauthorized information access, disruption of services, or elevation of user rights. For further details on the scope of these vulnerabilities, Microsoft has provided information in their Security Update Guide.
Stay vigilant; ensure that your systems are updated regularly to mitigate these threats.
