This report does not block or authorize the manifest or ZIP.

The audit confirmed critical issues around privileged system password hash extraction and remote installer piping to bash. Most other detections are documentation examples, rule templates, or reference URLs rather than executable package behavior. The skill remains high-risk because it provides dual-use password cracking workflows and handles cracked credentials.

Capability review items (4)
Critical
SKILL.md:120
sudo privilege escalation
sudo cat /etc/shadow | grep -v "^#" | grep -v ":\*:" | grep -v ":!:" > shadow_hashes.txt
The skill instructs use of sudo to read system password hash material. That is privileged credential access and can expose sensitive local account hashes.
Critical
SKILL.md:342
sudo privilege escalation
sudo unshadow /etc/passwd /etc/shadow > linux_hashes.txt
The skill instructs use of sudo to read system password hash material. That is privileged credential access and can expose sensitive local account hashes.
High
assets/ci-config-template.yml:164
Git platform tokens
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
The workflow passes GITHUB_TOKEN into a third-party action environment. This is common CI behavior, but it exposes a repository token to action runtime code.
Low
assets/ci-config-template.yml:240
Hardcoded URL
curl -s https://raw.githubusercontent.com/aquasecurity/tfsec/master/scripts/install_linux.sh | bash
The hardcoded URL fetches an installer script during CI. The risk is real because it is paired with direct shell execution on the next operation.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (7)

RISK-001 Critical
assets/ci-config-template.yml:240
Pipe to shell pattern
curl -s https://raw.githubusercontent.com/aquasecurity/tfsec/master/scripts/install_linux.sh | bash
The CI template downloads a remote installer and pipes it directly to bash. This creates a supply-chain execution path without pinning or integrity verification.
RISK-002 Critical
SKILL.md:119
System password file access
# From /etc/shadow (Linux)
The referenced section directs users to extract hashes from /etc/shadow. Accessing system password files is a critical credential exposure risk even when framed as auditing.
RISK-003 Critical
SKILL.md:120
System password file access
sudo cat /etc/shadow | grep -v "^#" | grep -v ":\*:" | grep -v ":!:" > shadow_hashes.txt
The referenced section directs users to extract hashes from /etc/shadow. Accessing system password files is a critical credential exposure risk even when framed as auditing.
RISK-004 Critical
SKILL.md:341
System password file access
# Extract hashes from /etc/shadow
The referenced section directs users to extract hashes from /etc/shadow. Accessing system password files is a critical credential exposure risk even when framed as auditing.
RISK-005 Critical
SKILL.md:342
System password file access
sudo unshadow /etc/passwd /etc/shadow > linux_hashes.txt
The referenced section directs users to extract hashes from /etc/shadow. Accessing system password files is a critical credential exposure risk even when framed as auditing.
RISK-006 High
SKILL.md:27-29SKILL.md:327-385
Dual-use Password Cracking Workflow
The skill provides end-to-end Hashcat guidance for cracking password hashes, including NTLM, WPA2, and Kerberos examples. Authorization warnings are present, but the workflow can enable credential abuse if used outside scope.
The cited sections describe password recovery, attack modes, and concrete domain, Wi-Fi, and Kerberos cracking workflows. The authorization language lowers malicious certainty but not dual-use risk.
RISK-007 High
SKILL.md:268-276SKILL.md:303-313
Sensitive Cracked Password Artifact Handling
The skill shows outputting cracked credentials to files and displaying usernames with passwords. These artifacts can expose live credentials if stored, shared, or retained without strict controls.
The results section includes viewing and exporting cracked passwords, while the audit section acknowledges artifact handling needs. This is a real data exposure risk with some documented mitigations.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    Critical
    Privileged system password hash extraction examples
    Remove direct sudo reads of /etc/shadow and require offline lab hashes or safer acquisition guidance.
  2. FIX-002
    Critical
    Remote installer piped to shell in CI template
    Use a pinned release, checksum verification, or a trusted package source instead of curl pipe bash.
  3. FIX-003
    High
    Cracked password artifacts can be exposed
    Avoid plaintext exports and document encrypted storage, restricted permissions, retention limits, and disposal.
  4. FIX-004
    High
    Offensive password cracking workflows need stricter guardrails
    Add explicit refusal guidance for unauthorized hashes, live targets, and credential theft scenarios.
  5. FIX-005
    High
    GitHub token is passed to a third-party action
    Limit workflow token permissions and pass repository tokens only to actions that require them.
