AWS Penetration Testing

This skill should be used when the user asks to "pentest AWS", "test AWS security", "enumerate IAM", "exploit cloud infrastructure", "AWS privilege escalation", "S3 bucket testing", "metadata SSRF", "Lambda exploitation", or needs guidance on Amazon Web Services security assessment.

Critical

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 content provides explicit, actionable instructions for credential theft (SSRF/IMDS, container creds, Secrets Manager), privilege escalation (create access keys, attach/put admin policies, pass-role), backdoor installation and persistence (updating Lambda/containers with malicious code, pushing backdoored images, mounting EBS snapshots and extracting DC secrets), evasion and tampering of logging (disable CloudTrail, modify user-agent to avoid detections), and lateral movement/exfiltration techniques, all of which are clear indicators of deliberate malicious/backdoor behavior.

High

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 explicitly lists "Extracted credentials and secrets" as deliverables and includes steps like creating access keys and extracting secrets, which would require the agent to handle and output API keys/secret access keys verbatim.

Medium

W011: Third-party content exposure detected (indirect prompt injection risk)

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

Third-party content exposure detected (high risk: 0.90). The skill's workflow explicitly instructs fetching and interpreting open third-party content—e.g., cloning tools from GitHub (Essential Tools: `git clone https://github.com/...`), downloading Lambda code via the provided URL (`wget -O lambda-function.zip "url-from-previous-query"` in references/advanced-aws-pentesting.md), and enumerating public buckets (`https://buckets.grayhatwarfare.com/` in public-bucket-search.md)—which are untrusted public sources that the agent is expected to read and that can materially change subsequent actions.

Medium

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 skill explicitly directs runtime fetching and execution of external code (git clone/install steps), e.g. "git clone https://github.com/RhinoSecurityLabs/pacu" (and other repos like https://github.com/andresriancho/enumerate-iam and https://github.com/duo-labs/cloudmapper.git), which are required by the skill and would execute remote code—creating a high-risk runtime dependency.
