Kind: security · Impact: medium

## In 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.
