Detection & IOCsextracted from sources · hover to see the quote
- →Exploitation vector involves convincing a user to open a specially crafted document or visit an untrusted webpage, triggering improper memory disclosure in the Windows GDI component ↗
- →The information disclosed is memory layout (ASLR bypass class), enabling an attacker to predict memory addressing — monitor for GDI-related memory leaks or suspicious document/browser activity on Windows 10 and Windows Server 2016 systems ↗
- ·Affected platforms are limited to Windows Server 2016, Windows 10, and Windows 10 Servers — exploitation likelihood rated 'More Likely' for both latest and older software releases ↗
