Detection & IOCsextracted from sources · hover to see the quote

pathMSKSSRV.SYS
pathks.sys
  • Monitor for local privilege escalation to SYSTEM via untrusted pointer dereference in the Microsoft Kernel Streaming Service (MSKSSRV.SYS / ks.sys) driver — exploitation requires no user interaction and is low complexity.
  • A public Metasploit module exists for this vulnerability targeting Windows 10, Windows 11, and Windows Server 2022; hunt for execution of exploit modules referencing 'cve_2024_35250_ks_driver'.
  • CVE-2024-35250 is confirmed actively exploited and listed in CISA KEV; prioritize detection of anomalous kernel-mode driver interactions with ks.sys/MSKSSRV.SYS on unpatched systems.
  • ·The Metasploit module targets Windows 10, Windows 11, and Windows Server 2022 specifically; the broader CVE patch scope covers a much wider range of Windows versions including Server 2008 through Server 2022 and Windows 10/11 variants.
  • ·Microsoft's advisory had not been updated to reflect active exploitation status at time of reporting, despite CISA adding it to the KEV catalog.
