structs-production

Security checks for vulnerabilities and agentic risk

Overview

This skill gives disclosed instructions for running Structs game production tasks, including long-running approved mining/refining jobs, without hidden install code or unrelated access.

Install only if you intend to use Structs automation with a configured signing key. Review each Approval Block carefully because the shown commands can run for many hours, consume compute, and auto-submit game transactions after launch.

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

Session Persistence

Medium
Category
Rogue Agent
Confidence
65% confidence
Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Content

Scanner excerpt · SKILL.md (reported line 54)May include surrounding context.

Approval Block — confirm before launch: extractor id is correct; planet currentOre > 0; --from is the owner key; you accept an auto-submitted completion ~17h out even if state shifts.

bash
nohup structsd tx structs struct-ore-mine-compute -D 3 --from [key] --gas auto --gas-adjustment 1.5 -y -- [extractor-id] \
  > memory/jobs/mine-[extractor-id].log 2>&1 & echo $! > memory/jobs/mine-[extractor-id].pid
