Detection & IOCsextracted from sources · hover to see the quote
- →Monitor for any process actively listening on a PGM (Pragmatic General Multicast) socket/port; exploitation requires an open PGM receiver socket on the target. ↗
- →Alert on inbound specially crafted PGM packets to Windows hosts with an open PGM socket, particularly from unauthenticated/external sources — PGM does not authenticate requests. ↗
- →Detect exploitation attempts targeting the Windows Reliable Multicast Transport Driver (RMCAST) via anomalous or malformed PGM packets sent to open sockets without user interaction. ↗
- ·Exploitation is only possible if a program is actively listening on a PGM port; systems with PGM installed but no active receiver are NOT exploitable. ↗
- ·Network-level controls (e.g., firewall blocking PGM ports) are a recommended mitigation; PGM receivers should never be exposed to the public internet. ↗

Windows Reliable Multicast Transport Driver (RMCAST) Remote Code Execution Vulnerability
FAQ: How could an attacker exploit this vulnerability?
An unauthenticated attacker could exploit the vulnerability by sending specially crafted packets to a Windows Pragmatic General Multicast (PGM) open socket on the server, without any interaction from the user.
FAQ: Windows 11, version 24H2 is not generally available yet. Why are there updates for this version of Windows listed in the Security Updates table?
The new Copilot+ devices that are now publicly available come with Windows 11, version 24H2 installed. Customers with these devices need to know about any vulnerabilities that affect their machine and to install the updates if they are not receiving automatic updates. Note that the general ava

[MEDIUM] Talos discovers denial-of-service vulnerability in Microsoft Audio Bus; Potential remote code execution in popular open-source PLC
Cisco Talos’ Vulnerability Research team recently disclosed two vulnerabilities in Microsoft products that have been patched by the company over the past two Patch Tuesdays.
One is a vulnerability in the High-Definition Audio Bus Driver in Windows systems that could lead to a denial of service, while the other is a memory corruption issue that exists in a multicasting protocol in Windows 10.
Additionally, Talos researchers have disclosed three vulnerabilities in OpenPLC, a popular open-source programmable logic controller.
