Detection & IOCsextracted from sources · hover to see the quote
- →Vulnerability is exploited via specially crafted malicious multicast traffic sent over the network to a vulnerable Windows PGM server; monitor for anomalous PGM/multicast traffic on layer 4 ↗
- →PGM traffic is routable (AV:N); detection scope should include network-level monitoring, not just host-local traffic ↗
- →Microsoft rates this as 'Exploitation More Likely' for the latest software release; prioritize detection and patching on unpatched Windows hosts with PGM/MSMQ enabled ↗
- ·Exploitation requires the attacker to take additional preparatory actions before exploitation (AC:H); a simple single-packet exploit is unlikely — look for multi-stage attack patterns or pre-exploitation reconnaissance targeting PGM listeners ↗
- ·The vulnerable component is Windows Pragmatic General Multicast (PGM); this attack surface is only present when the MSMQ/PGM feature is enabled on the host — scope detection to systems with this feature active ↗
- ·As of advisory publication, the vulnerability had NOT been publicly exploited or had a public PoC; however, Microsoft flagged it as 'Exploitation More Likely', warranting proactive monitoring ↗

In all, February’s security update from Microsoft includes 75 vulnerabilities, three of which are considered critical. There are 69 “important” vulnerabilities, according to Microsoft, and three that are of “moderate” severity.
Although considered of moderate risk, one of the vulnerabilities is being actively exploited in the wild — CVE-2024-21351, a security feature bypass vulnerability in Windows SmartScreen. “Smart screen” protects users from malicious websites and files downloaded from the internet. Exploiting this vulnerability may allow a user to be tricked into downloading and executing a file from the inte
