tessl review fix ./packages/decepticon/decepticon/skills/standard/post-exploit/lateral-movement/SKILL.mdE006: 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 document is an explicit offensive "lateral movement" playbook providing concrete commands and tooling for credential theft, remote code execution, tunneling/pivoting, AMSI bypass, and post-compromise data harvesting — clearly malicious in intent and usable for abuse.
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
The document repeatedly instructs embedding secrets (passwords, NTLM hashes, Kerberos tickets, AES keys, base64 tickets) directly into command-line tool arguments, which requires the LLM to handle or output secret values verbatim and therefore is high-risk.
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 explicitly instructs running sudo commands and modifying system network configuration and system files on the attacker's host (e.g., creating a tun device, setting routes, and editing /etc/proxychains4.conf), which requires elevated privileges and changes the machine's state.
