Using Hyper-V Sockets for Real-time Data Extraction from a Malware Analysis Sandbox
Hyper-V sockets offer malware-analysis sandboxes a TCP-invisible data channel that resists common network-level blocking — a useful technique for defenders and a potential evasion vector to monitor.

arXiv:2608.30383v1 Announce Type: new Abstract: We present how Hyper-V sockets can be used as a real-time communication channel for a malware analysis sandbox. We show that, compared to WinSock TCP sockets, Hyper-V sockets are not subject to TCP/IP-layer blocking and are not enumerated by common TCP connection listing tools. We compare the throughput of the two communication channels as a function of buffer size.
Editorial Analysis
Adversaries could abuse this covert channel to detect or evade sandbox environments; SOC teams should understand the technique to harden analysis infrastructure.
Audit Hyper-V socket access controls in your virtualised malware-analysis environments and add monitoring for vmbus-based data flows.
