3 findings: 2 critical severity, 1 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
These URLs point to command-and-control frameworks, agent repositories, and a custom callback domain commonly used to build and distribute implant executables and profiles, making them high-risk sources for malware distribution.
E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
This content is high-risk malicious operational guidance: it describes building and running C2 infrastructure, implant creation and obfuscation, credential theft, lateral movement, persistence, and data exfiltration with OPSEC evasion techniques.
W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
The skill includes explicit instructions to create/modify system-level configuration and files (e.g., an /etc/nginx sites file, Let's Encrypt cert paths) and to start containers via docker compose, actions that require elevated privileges and change the host state.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The skill includes setup/install commands that git-clone and install remote repositories (e.g., https://github.com/HavocFramework/Havoc and https://github.com/its-a-feature/Mythic and several github agent/profile repos), which fetch remote code and are executed/built as required dependencies for the skill.
