Security audit
Timezone Helper
Security checks for vulnerabilities and agentic risk
Overview
This is an offline time-zone helper made of Markdown reference material with no scripts, credentials, network access, persistence, or hidden behavior.
This looks safe to install from a security perspective. Treat its time-zone and DST data as a convenience reference, not an authority for high-stakes scheduling, because time-zone rules can change and the skill itself notes that precise current-time answers depend on the system clock.
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
Vulnerability Patterns
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
