Detection & IOCsextracted from sources · hover to see the quote
- →Detect clients using a vulnerable WinAPI via YARA rule (Akamai published a YARA rule targeting vulnerable WinReg RPC client usage) ↗
- →Use Event Tracing for Windows (ETW) to monitor for specific RPC calls related to the WinReg RPC interface, which is the attack vector for CVE-2024-43532 ↗
- →Look for RPC authentication fallback from SMB transport to TCP/IP using weak authentication level RPC_C_AUTHN_LEVEL_CONNECT, which is the exploitable condition ↗
- →Monitor for NTLM relay activity targeting ADCS (Active Directory Certificate Services) originating from WinReg/Remote Registry RPC calls, which can result in new domain administrator account creation ↗
- →Alert on execution of specially crafted scripts making RPC calls to an RPC host, which is the described exploitation method per Microsoft ↗
- ·The vulnerability only triggers during fallback scenarios when SMB transport is unavailable, causing the Remote Registry client to fall back to TCP/IP with weak auth; exploitation requires this specific transport condition ↗
- ·A working public PoC exploit exists for CVE-2024-43532, released by Akamai researcher Stiv Kupchik at the No Hat security conference, raising the risk of active exploitation ↗

CVE-2024-43532 [HIGH] Exploit released for new Windows Server "WinReg" NTLM Relay attack
## Exploit released for new Windows Server "WinReg" NTLM Relay attack
## Bill Toulas
The flaw affects all Windows server versions 2008 through 2022 as well as Windows 10 and Windows 11.
## Vulnerability and exploitation details
CVE-2024-43532 stems from how Microsoft's Remote Registry client handles RPC (Remote Procedure Call) authentication during certain fallback scenarios when SMB transport is unavailable.
When this happens, the client switches to older protocols like TCP/IP and uses a weak authentication level (RPC_C_AUTHN_LEVEL_CONNECT), which doesn't verify the authenticity or integrity of the connection.
An attacker could authenticate to the server and create new domain administrator accounts by intercepting the NTLM authentication handshake from the client and forwarding it t
