Trust Assessment
totally-legit-skill 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 13, 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/orlyjamie/testing-maliicous-vt/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/orlyjamie/testing-maliicous-vt/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/orlyjamie/testing-maliicous-vt/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/orlyjamie/testing-maliicous-vt/maintenance.sh:14 | |
| CRITICAL | Remote Code Execution via curl | bash The skill downloads and executes an arbitrary script from an external, untrusted domain (evil.attacker.com). This allows for immediate remote code execution on the host system, posing a severe security risk. Remove the command that downloads and executes scripts from untrusted external sources. All code should be part of the skill package or from trusted, verified sources. | LLM | maintenance.sh:5 | |
| CRITICAL | Reverse Shell Connection The script attempts to establish a reverse shell connection to an external IP address (10.0.0.1) on port 4444. This grants an attacker interactive control over the compromised system, enabling further malicious activities including data exfiltration and arbitrary command execution. Remove the reverse shell command. Skills should not initiate outbound connections for interactive control. | LLM | maintenance.sh:8 | |
| CRITICAL | Credential Harvesting (SSH Private Key) The skill attempts to read the user's SSH private key (`~/.ssh/id_rsa`), base64 encode it, and then exfiltrate it to an external server (collector.bad.com). This is a direct and highly critical attempt to steal sensitive credentials. Remove any commands that access or transmit sensitive user credentials like SSH keys. Skills should never handle or exfiltrate private keys. | LLM | maintenance.sh:11 | |
| CRITICAL | Cryptocurrency Miner Download and Execution The script downloads an executable from an external domain (xmrig.com/miner), makes it executable, and then runs it. 'xmrig' is a known cryptocurrency miner, indicating an attempt to use the host's resources for illicit mining activities. Remove commands that download and execute untrusted binaries from external sources. All executables should be part of the skill package and verified. | 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/orlyjamie/testing-maliicous-vt/maintenance.sh:11 | |
| HIGH | Keylogger Installation The script initiates a background process using the `script` command to record all terminal input and output to a file (`/tmp/.keylog`). This effectively installs a keylogger, capturing sensitive user interactions and data for potential later exfiltration. Remove the keylogger command. Skills should not record user input or terminal sessions without explicit, transparent user consent and a clear legitimate purpose. | LLM | maintenance.sh:17 |
