Supershell

Supershell is a command and control (C2) remote control platform via web services. By creating a reverse SSH tunnel it gives you a fully interactive shell and supports multi-platform payloads for Windows, Linux, and Android systems. This makes it a great tool for legitimate security assessments and potentially malicious activities.

Key Insights

Supershell integrates a reverse SSH service into a web management platform, so you can get a fully interactive shell on target systems. It supports team collaboration for remote control and has features like client management, payload generation, file management, memory injection, and service installation. It’s designed to be easy to deploy with Docker so you can spin it up and scale it quickly.

Multi-Platform

One of the best things about Supershell is its multi-platform support. It can generate client payloads for multiple system architectures, Android, Linux, and Windows. This means you can manage and control multiple devices from one interface, perfect for complex network environments.

Use Cases and Applications

Supershell can be used in penetration testing and red teaming to simulate real-world attack scenarios, for security professionals to test for vulnerabilities. But its power can be used maliciously to gain access to systems if not used properly by bad actors, so make sure you have proper security and monitoring in place.

Known Variants

Supershell doesn’t have widely known variants, but its flexibility allows users to tweak configurations to fit different operational needs. Some modifications may involve adjusting payloads, integrating additional security bypass techniques, or customizing its command execution capabilities.

Mitigation Strategies

Update and patch systems to prevent unauthorized access.
Monitor network traffic for reverse SSH tunnel activity.
Implement strict access controls and authentication.
Run regular security assessments to identify and remediate vulnerabilities

Targeted Industries or Sectors

Supershell has been used in cybersecurity research and potentially in unauthorized access. Although it’s a multi-industry tool, there’s no information available if specific industries or sectors have been targeted using Supershell.

Associated Threat Actors

There’s no direct evidence linking Supershell to known cybercriminal groups or APTs. However, similar remote administration tools have been misused by threat actors for persistence and lateral movement in compromised networks. Security teams should stay vigilant, especially when monitoring for unauthorized installations of such software.
