## What it is
A Java bytecode analyzer that automatically discovers deserialization gadget chains in Java libraries and application classpaths. It produces a list of potential gadget chains that penetration testers and security engineers can use to exploit or assess the impact of Java deserialization vulnerabilities.

## Use cases
- find deserialization gadget chains in java jars
- analyze a war file for java deserialization vulnerabilities
- discover exploit chains in commons-collections
- assess impact of a java deserialization vulnerability
- statically scan java classpath for dangerous gadget chains
- prioritize remediation of insecure java deserialization

## When to choose
- you need to automatically discover deserialization gadget chains in Java bytecode
- you are a penetration tester building exploits for Java deserialization flaws
- you are a security engineer assessing which libraries enable deserialization attacks

## When to avoid
- you need a maintained tool with active development and tests
- you are scanning non-Java applications
- you have limited memory since analysis is memory-intensive and unoptimized

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: security, vulnerability-scanning, penetration-testing, parser, developer-tools
- domain: security, penetration-testing, developer-tools, reverse-engineering
- platform: jvm, cli, cross-platform
- tags: java-bytecode-analysis, deserialization, gadget-chains, exploit-discovery, static-analysis
