LogTail Smart Log Monitor & Analyzer

Security checks for vulnerabilities and agentic risk

Overview

This skill locally watches user-selected log files and summarizes recent entries, with no evidence of network transmission, credential access, destructive actions, or persistence beyond active file watching.

Install only if a lightweight local log tailing helper is acceptable. Do not rely on the advertised anomaly alerting, highlighting, or correlation features without adding or verifying that functionality, and avoid pointing it at logs containing secrets unless local processing by the agent is acceptable.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

Finding
The core declared purpose of real-time log monitoring and summarization is broadly consistent with the code. It does watch files in real time, filter ignored lines, classify severities, and summarize recent errors/warnings. However, the description claims alerting on anomalies and surfacing anomalies/patterns more generally, which the code does not implement. There is no anomaly detection logic, thresholding, notification mechanism, or alert trigger. The 'highlight' filter option is declared in code but unused. This is a description-to-behavior mismatch due to overstated capabilities, though not a malicious or unrelated one.

Skill's behavior or capabilities extend beyond its stated purpose. Scope creep allows an agent to perform actions unrelated to its documented functionality, increasing the attack surface.
