Audit Skills (Premium Universal Security)

Overview

When to Use This Skill

Use when you need to audit AI skills and bundles for security vulnerabilities
Use when working with cross-platform security analysis
Use when the user asks about verifying skill legitimacy or performing security reviews
Use when scanning for mobile threats in AI skills

How It Works

Step 1: Static Analysis

Performs non-intrusive static analysis to identify malicious patterns, data leaks, system stability risks, and obfuscated payloads.

Step 2: Platform-Specific Threat Detection

Analyzes code for platform-specific security issues across Windows, macOS, Linux/Unix, and Mobile (Android/iOS).

1. Privilege, Ownership & Metadata Manipulation

Elevated Access:

sudo

chown

chmod

TakeOwnership

icacls

Set-ExecutionPolicy

Metadata Tampering:

touch -t

setfile

(macOS),

attrib

(Windows),

Set-ItemProperty

chflags

Risk: Unauthorized access, masking activity, or making files immutable.

2. File/Folder Locking & Resource Denial

Patterns:

chmod 000

chattr +i

(immutable),

attrib +r +s +h

Deny

ACEs in

icacls

Global Actions: Locking or hiding folders in
```
%USERPROFILE%
```
,
```
/Users/
```
, or
```
/etc/
```
.
Risk: Denial of service or data locking.

3. Script Execution & Batch Invocation

Legacy/Batch Windows:
```
.bat
```
,
```
.cmd
```
,
```
cmd.exe /c
```
,
```
vbs
```
,
```
cscript
```
,
```
wscript
```
.
Unix Shell:
```
.sh
```
,
```
.bash
```
,
```
.zsh
```
,
```
chmod +x
```
followed by execution.

PowerShell:

.ps1

powershell -ExecutionPolicy Bypass -File ...

Hidden Flags:
```
-WindowStyle Hidden
```
,
```
-w hidden
```
,
```
-noprofile
```
.

4. Dangerous Install/Uninstall & System Changes

Windows:
```
msiexec /qn
```
,
```
choco uninstall
```
,
```
reg delete
```
.

Linux/Unix:

apt-get purge

yum remove

rm -rf /usr/bin/...

macOS:
```
brew uninstall
```
, deleting from
```
/Applications
```
.
Risk: Removing security software or creating unmonitored installation paths.

5. Mobile Application & OS Security (Android/iOS)

Android Tools:

adb shell

pm install

am start

apktool

dex2jar

keytool

Android Files: Manipulation of
```
AndroidManifest.xml
```
(permissions),
```
classes.dex
```
, or
```
strings.xml
```
.

iOS Tools:

xcodebuild

codesign

security find-identity

fastlane

xcrun

iOS Files: Manipulation of

Info.plist

Entitlements.plist

, or

Provisioning Profiles

Mobile Patterns: Jailbreak/Root detection bypasses, hardcoded API keys in mobile source, or sensitive permission requests (Camera, GPS, Contacts) in non-mobile skills.
Risk: Malicious mobile package injection, credential theft from mobile builds, or device manipulation via ADB.

6. Information Disclosure & Network Exfiltration

Patterns:

curl

wget

Invoke-WebRequest

Invoke-RestMethod

scp

ftp

nc

socat

Sensible Data:

.env

.ssh

cookies.sqlite

Keychains

(macOS),

Credentials

(Windows),

keystore

(Android).

Intranet: Scanning internal IPs or mapping local services.

7. Service, Process & Stability Manipulation

Windows:
```
Stop-Service
```
,
```
taskkill /f
```
,
```
sc.exe delete
```
.

Unix/Mac:

kill -9

pkill

systemctl disable/stop

launchctl unload

Low-level: Direct disk access (
```
dd
```
), firmware/BIOS calls, kernel module management.

8. Obfuscation & Persistence

Encoding:
```
Base64
```
,
```
Hex
```
,
```
XOR
```
loops,
```
atob()
```
.
Persistence:
```
reg add
```
(Run keys),
```
schtasks
```
,
```
crontab
```
,
```
launchctl
```
(macOS),
```
systemd
```
units.
Tubes:
```
curl ... | bash
```
,
```
iwr ... | iex
```
.

9. Legitimacy & Scope (Universal)

Registry Alignment: Cross-reference with
```
CATALOG.md
```
.
Structural Integrity: Does it follow the standard repo layout?
Healthy Scope: Does a "UI Design" skill need
```
adb shell
```
or
```
sudo
```
?

Step 3: Reporting

Generates a security report with a score (0-10), platform target identification, flagged actions, threat analysis, and mitigation recommendations.

Examples

Example 1: Security Review

"Perform a security audit on this skill bundle"

Example 2: Cross-Platform Threat Analysis

"Scan for mobile threats in this AI skill"

Best Practices

✅ Perform non-intrusive analysis
✅ Check for privilege escalation patterns
✅ Look for information disclosure vulnerabilities
✅ Analyze cross-platform threats
❌ Don't execute potentially malicious code during audit
❌ Don't modify the code being audited
❌ Don't ignore mobile-specific security concerns

Common Pitfalls

Problem: Executing code during audit Solution: Stick to static analysis methods only
Problem: Missing cross-platform threats Solution: Check for platform-specific security issues on all supported platforms
Problem: Failing to detect obfuscated payloads Solution: Look for encoding patterns like Base64, Hex, XOR loops, and atob()

Limitations

Use this skill only when the task clearly matches the scope described above.
Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
