## What it is
A JSP-based scanner that detects and helps remove Java web memory shells (memshells) such as Filter, Servlet, and Listener types in middleware like Tomcat. It offers a gentler alternative to Java agent-based detection tools.

## Use cases
- scan tomcat for memory shells
- detect filter servlet memshell in java web app
- find listener type memshell
- remove malicious in-memory webshell from middleware
- incident response for java memshell infection

## When to choose
- you need to detect memshells without deploying a Java agent
- you want a lightweight JSP script you can drop onto a compromised Tomcat server
- you need to check Filter, Servlet, and Listener type memory shells

## When to avoid
- you need to scan non-Java middleware or non-JVM applications
- you require ongoing automated monitoring rather than on-demand scanning
- you need a maintained tool with active releases and a license

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: security, vulnerability-scanning, reverse-engineering
- domain: security, penetration-testing
- platform: jvm
- tags: memshell, jsp, tomcat, incident-response, java-web, java, web-server
