pt-lotl-techniques

Demonstrates Living-off-the-Land (LotL) techniques using native OS tools to simulate realistic threat actor behavior during authorized penetration tests. Use when proving attack feasibility without custom malware, testing detection coverage, and validating what a real adversary could achieve with only built-in system capabilities.

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). The document explicitly details techniques for credential theft, persistence, lateral movement, remote code execution, and data exfiltration using built-in OS tools—high-risk, dual‑use behaviors that can enable backdoors and unauthorized compromise despite being framed for authorized testing.

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 prompt explicitly instructs reading credential files/outputs and to "record full command line" and "Output observed," which would require capturing and outputting secret values verbatim if present.

Medium

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 prompt explicitly instructs creating/modifying persistence mechanisms (services, systemd units, cron, registry run keys, SSH authorized_keys), using sudo abuse and lateral-movement techniques—actions that change system state and require/encourage privileged access.
