The global socket: how threat actors are weaponizing GSocket for stealthy C2
Microsoft · By Yash Gund, Sumith Maniath & Microsoft Security Research ·
The Brief
- Microsoft reports observing multiple incidents in which threat actors used GSocket for command-and-control (C2).
- The article covers observed attack chains, how threat actors deploy and operate GSocket, and how it reconnects without a fixed C2 address.
- The article includes mitigation and protection guidance.
Why it matters
GSocket lets attackers reconnect without a fixed C2 address, so blocking a known IP or domain may not stop an intrusion. Defenders should review the attack chains and mitigations in the Microsoft article.
What to do
- Review the mitigation and protection guidance in the Microsoft Security Blog article.
