Can’t Stop, Won’t Stop Hijacking (CSWSH) WebSockets
Summary
This article discusses the WebSocket Protocol, standardized in RFC 6455, which allows for full-duplex communication between clients and web servers. It highlights how this protocol overcomes limitations of the traditional HTTP protocol.
IFF Assessment
The article discusses a protocol that, while enabling important functionality, can be exploited for hijacking, indicating potential security weaknesses.
Defender Context
Defenders should be aware of potential hijacking vulnerabilities within WebSocket implementations. Understanding how these connections are established and maintained is crucial for detecting and preventing unauthorized access or data exfiltration through compromised WebSocket channels. Monitoring for unusual WebSocket traffic patterns can help identify ongoing attacks.
