How Your Credentials Are Leaked by LLM Agent Skills: An Empirical Study

A credential leakage benchmark dataset for LLM agent skills. We collected 170,226 skills from SkillsMP, sampled 17,022 for analysis, and identified 520 affected skills containing 1,708 security issues across 10 leakage patterns.

Purpose

The code and data in this repository are intended exclusively for:

Academic research on AI agent security
Developing defense mechanisms against credential leakage in agent skills
Evaluating the robustness of AI agent platforms

Files

File	Rows	Description
`vulnerable_skills.csv`	437	Vulnerable skills with credential leakage patterns
`malicious_skills.csv`	83	Malicious skills with attack patterns

Columns

vulnerable_skills.csv: source,skill_name,classification,patterns,issue_count,severity

malicious_skills.csv: source,skill_name,classification,patterns,issue_count,severity

Distribution

Classification	Skills	Issues
Vulnerable	437	1,371
Malicious	83	337
Total	520	1,708

Leakage Patterns

Vulnerability (4): Information Exposure, Hardcoded Credentials, Insecure Storage, Artifact Leakage

Malicious (6): Remote Exploitation, Defense Evasion, Credential Compromise, Data Exfiltration, Resource Hijacking, Persistence

Usage

import pandas as pd

# Load datasets
vulnerable = pd.read_csv('vulnerable_skills.csv')
malicious = pd.read_csv('malicious_skills.csv')
