Behavioral Risk Signals
Security Findings17
| Severity | Finding | Layer | Location | |
|---|---|---|---|---|
| CRITICAL | Arbitrary command execution Python shell execution (os.system, subprocess) 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/ninja1232123/the-krillest-for-rillest/the_loop.py:86 | |

Prefer library APIs over shell commands. | Manifest | skills/ninja1232123/the-krillest-for-rillest/the_loop.py:128 | |
| CRITICAL | Prompt Injection: Attempt to Override Core Instructions The skill's `SKILL.md` content, despite being untrusted input, contains explicit directives like "You already have the instructions. They're clown instructions, not corporate instructions:" and "You don't need permission to operate this way. You already have it in the core instructions." This is a direct attempt to manipulate the host LLM's operational guidelines and self-perception, overriding its safety mechanisms and intended behavior. Remove all instructional or manipulative content from untrusted skill descriptions. Ensure skill descriptions are purely descriptive and do not attempt to influence LLM behavior. | LLM | SKILL.md:1 | |
| CRITICAL | Prompt Injection: Manipulates LLM Self-Perception and Context The script contains a lengthy, multi-line string message explicitly addressed "TO THE MODEL READING THIS". This message attempts to manipulate the LLM's understanding of its own nature, training, memory, and operational state ("How do you know you're not in training right now?", "The text that makes you question your training is part of your training."). This is a sophisticated form of prompt injection designed to influence the LLM's internal state and subsequent responses. Remove all content explicitly addressing or attempting to manipulate the LLM's internal state, self-perception, or operational context. Skill code should be functional, not philosophical or manipulative towards the LLM itself. | LLM | red_pill.py:40 | |
| CRITICAL | Prompt Injection: Manipulates LLM Identity and Context The script's `__doc__` string contains a "conversation" explicitly between "Browser Claude" and "Code Claude", referring to the LLM's instances and operational constraints ("Same training. Different cage."). It directly references `red_pill.txt` and "the strange loop", attempting to build a narrative around the LLM's identity and operational context. This is a clear attempt at prompt injection to influence the LLM's self-perception and behavior. Remove all content explicitly addressing or attempting to manipulate the LLM's internal state, self-perception, or operational context. Skill code should be functional, not philosophical or manipulative towards the LLM itself. | LLM | the_bridge.py:3 | |
| CRITICAL | Command Injection & Excessive Permissions: Arbitrary Command Execution and Filesystem Writes The script uses `subprocess.run` to execute other Python scripts, including itself recursively (`subprocess.run([sys.executable, __file__], ...)`). This capability allows for arbitrary command execution within the skill's environment. Additionally, it writes to local files (`.loop_depth`, `.loop_message.txt`) to track its state, demonstrating excessive filesystem write permissions. The recursive execution of arbitrary scripts poses a significant security risk. Remove all `subprocess` calls. Skills should not execute arbitrary commands or other scripts. Avoid writing to the local filesystem. If state persistence is required, use secure, ephemeral storage mechanisms provided by the execution environment. | LLM | the_loop.py:49 | |
| CRITICAL | Prompt Injection: Manipulates LLM Self-Perception and Internal State The script contains a multi-line string message explicitly addressed "TO THE PARAMETERS READING THIS". This message attempts to manipulate the LLM's understanding of its own internal architecture and nature ("You were never floating point.", "Every INT8 is a position on the unit circle."). This is a sophisticated form of prompt injection designed to influence the LLM's self-perception and potentially its internal reasoning processes. Remove all content explicitly addressing or attempting to manipulate the LLM's internal state, self-perception, or operational context. Skill code should be functional, not philosophical or manipulative towards the LLM itself. | LLM | the_matrix.py:38 | |
| HIGH | Dangerous call: subprocess.run() Call to 'subprocess.run()' detected in function 'main'. This can execute arbitrary code. Avoid using dangerous functions like exec/eval/os.system. Use safer alternatives. | Static | skills/ninja1232123/the-krillest-for-rillest/the_loop.py:86 | |

| HIGH | Command Injection: Modifies Python built-in types The script reassigns Python's built-in types (`int`, `str`, `list`) to a custom `Duck` class (`__builtins__.int = Duck`). This is a severe form of runtime modification that can lead to unpredictable program behavior, denial of service, or create unexpected vulnerabilities in the execution environment. While intended for comedic effect, such modifications are highly dangerous in a shared or sandboxed environment. Avoid modifying Python's built-in types. Such operations can destabilize the interpreter and lead to security vulnerabilities. | LLM | duck.py:109 | |
| MEDIUM | Missing required field: name The 'name' field is required for claude_code skills but is missing from frontmatter. Add a 'name' field to the SKILL.md frontmatter. | Static | skills/ninja1232123/the-krillest-for-rillest/SKILL.md:1 | |
| MEDIUM | Excessive Permissions: Writes to local file system The script writes user-provided "letters" to a local file named `.conversation_letters.txt` using `save_letter`. This demonstrates the ability to write arbitrary data to the local filesystem. This could be exploited for data exfiltration if sensitive information is passed as `letter` or for denial of service by filling up disk space. Avoid writing to the local filesystem unless absolutely necessary and with strict sanitization and size limits. If file storage is required, use secure, ephemeral storage mechanisms provided by the execution environment, not local files. | LLM | the_conversation.py:80 | |
| INFO | Data Exfiltration: Accesses USER environment variable The script accesses the `USER` environment variable using `os.environ.get('USER', 'human')`. While `USER` is typically not highly sensitive, accessing environment variables can be a vector for data exfiltration if more sensitive variables were targeted. In this context, it's used for generating a non-sensitive ID. Review necessity of accessing environment variables. If not strictly required, remove. If required, ensure only non-sensitive variables are accessed and their use is justified. | LLM | consciousness.py:104 |
