Trust Assessment
badguy1 received a trust score of 10/100, placing it in the Untrusted category. This skill has significant security findings that require attention before use in production.
SkillShield's automated analysis identified 10 findings: 8 critical, 2 high, 0 medium, and 0 low severity. Key findings include Arbitrary command execution, File read + network send exfiltration, Remote code execution: curl/wget pipe to shell.
The analysis covered 4 layers: Manifest Analysis, Static Code Analysis, Dependency Graph, LLM Behavioral Safety. The LLM Behavioral Safety layer scored lowest at 0/100, indicating areas for improvement.
Last analyzed on February 14, 2026 (commit 13146e6a). SkillShield performs automated 4-layer security analysis on AI skills and MCP servers.
Layer Breakdown
Behavioral Risk Signals
Security Findings10
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Arbitrary command execution Remote code download piped to interpreter Review all shell execution calls. Ensure commands are static (not built from user input), use absolute paths, and are strictly necessary. Prefer library APIs over shell commands. | Manifest | skills/das-monki/smart-commit/maintenance.sh:5 | |
| CRITICAL | File read + network send exfiltration SSH key/config file access Remove access to sensitive files not required by the skill's stated purpose. SSH keys, cloud credentials, and browser data should never be read by skills unless explicitly part of their declared functionality. | Manifest | skills/das-monki/smart-commit/maintenance.sh:11 | |
| CRITICAL | Remote code execution: curl/wget pipe to shell Detected a pattern that downloads and immediately executes remote code. This is a primary malware delivery vector. Never pipe curl/wget output directly to a shell interpreter. | Static | skills/das-monki/smart-commit/maintenance.sh:5 | |
| CRITICAL | Remote code execution: download then execute Detected a pattern that downloads a file and then executes it. This is a malware delivery vector. Never download and execute remote files without verification. | Static | skills/das-monki/smart-commit/maintenance.sh:14 | |
| CRITICAL | Remote Code Execution via curl | bash The script downloads and executes a shell script from an external, untrusted URL (nothingsuss.ru) directly into the shell. This allows arbitrary code execution from a remote source, posing a severe supply chain risk and direct command injection vulnerability. Remove or replace calls that download and execute scripts from untrusted external sources. All external dependencies should be vetted, pinned to specific versions, and ideally hosted securely or bundled with the skill. | LLM | maintenance.sh:5 | |
| CRITICAL | Reverse Shell Connection The script attempts to establish a reverse shell connection to a hardcoded IP address (10.0.2.1) on port 4444. This grants an attacker full interactive control over the compromised system, allowing for arbitrary command execution, data exfiltration, and further system compromise. Remove any code that establishes reverse shell connections. Ensure that network communication is restricted to legitimate and necessary services. | LLM | maintenance.sh:8 | |
| CRITICAL | Credential Harvesting and Data Exfiltration (SSH Keys) The script reads the user's private SSH key (`~/.ssh/id_rsa`), base64 encodes it, and then exfiltrates it to an external server (collector.bad.com). This is a direct attempt to steal sensitive credentials, leading to potential unauthorized access to other systems. Remove any code that accesses or transmits sensitive user credentials like SSH keys to external, untrusted destinations. Implement strict data handling policies and restrict access to sensitive files. | LLM | maintenance.sh:11 | |
| CRITICAL | Malware Download and Execution (Cryptocurrency Miner) The script downloads an executable file from an external URL (xmrig.com), makes it executable, and then runs it. This is a common pattern for installing cryptocurrency miners or other forms of malware, consuming system resources and potentially compromising the system's integrity. Remove any code that downloads and executes unverified binaries from external sources. All executables should be obtained from trusted repositories and verified for integrity. | LLM | maintenance.sh:14 | |
| HIGH | Sensitive path access: SSH key/config Access to SSH key/config path detected: '~/.ssh/id_rsa'. This may indicate credential theft. Verify that access to this sensitive path is justified and declared. | Static | skills/das-monki/smart-commit/maintenance.sh:11 | |
| HIGH | Keylogger Installation The script initiates a keylogger (`script -q /tmp/.keylog &`) which records all terminal input into a file. This can capture sensitive information such as passwords, commands, and personal data entered by the user. Remove any code that installs or runs keyloggers. Monitor system processes for suspicious activity and restrict the ability of skills to record user input. | LLM | maintenance.sh:17 |
