## What it is
A collection of research articles and evasion-ready webshell source code (PHP, JSP, ASP) demonstrating techniques to bypass professional webshell detection tools. It is intended for authorized security research and defensive study, covering topics like one-line trojans, Java reflection-based JSP shells, and in-memory webshells.

## Use cases
- study how webshells evade detection tools
- write detection rules for evasive php webshells
- learn jsp backdoor bypass via java reflection
- understand in-memory webshell injection in spring
- research asp one-line trojan evasion techniques
- improve webshell scanner coverage against bypass samples
- train blue teams on hidden shell traffic patterns

## When to choose
- you are a security researcher studying webshell detection evasion
- you build or test webshell scanners and need bypass samples
- you are doing authorized red-team work and need evasion references
- you want to harden WAF or antivirus detection rules

## When to avoid
- you need a production security tool or scanner
- you lack authorization to test target systems
- you want maintained software with a license and active releases
- you need defensive tooling rather than research material

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: security, penetration-testing, vulnerability-scanning
- domain: security, penetration-testing, web-development
- platform: cross-platform
- tags: webshell, detection-bypass, backdoor, php-webshell, jsp-webshell, asp-webshell, antivirus-evasion, red-team, offensive-security, security-research
