Dns Networking Tool Free

Overview

This network diagnostic skill has a coherent purpose, but it under-discloses outbound network traffic and includes privileged, state-changing commands without clear safeguards.

Install only if you are comfortable with an agent running network probes to the targets you name. Before use, require confirmation for every external host contacted and do not allow sudo, DNS cache flushing, or /etc/hosts edits unless you specifically requested and reviewed those changes.

Vulnerability Patterns

• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access
• Tool Misuse: Tool Parameter Abuse, Chaining Abuse, Unsafe Defaults
• Trigger Abuse: Overly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
• Behavioral AST: exec() Call, eval() Call, Dynamic Import

Findings (11)

Intent-Code Divergence

High

• Confidence: 98% confidence
• Finding: The skill claims that all diagnostics run locally and do not send data to external services, but the documented commands explicitly perform outbound DNS, HTTP, and TLS connections to remote hosts. This is dangerous because it misleads users and calling agents about data flow and network side effects, undermining informed consent and any policy controls that depend on accurate disclosure.

Vague Triggers

Medium

• Confidence: 84% confidence
• Finding: The trigger conditions are overly broad ('code generation, programming assistance, debugging, deployment') relative to the actual network-diagnostics scope, which increases the chance that an agent invokes this exec-capable skill in unrelated contexts. That raises the risk of unintended command execution and outbound probing when the user did not specifically request network diagnostics.

Missing User Warnings

Medium

• Confidence: 94% confidence
• Finding: This section includes commands that modify system state or require elevated privileges, such as flushing DNS caches, but does not clearly warn users that these actions affect host configuration and may require admin rights. In an agentic exec context, insufficient warning can lead to disruptive changes on the local machine without adequate user awareness.

Missing User Warnings

High

• Confidence: 97% confidence
• Finding: The best-practice example appends an entry to /etc/hosts using sudo, which changes local name resolution and can redirect traffic, yet it lacks a prominent warning about the security and availability risks. In an exec-enabled skill, this could misroute connections, mask real DNS behavior, or persist unsafe overrides if cleanup fails.
