0bull-iphone-control

Security checks for vulnerabilities and agentic risk

Overview

This skill clearly documents remote control of a rented iPhone and includes proportionate safeguards for costly, destructive, or sensitive actions.

Install only if you intend to let 0bull and the agent operate a rented iPhone. Review actions involving accounts, clipboard contents, passwords, codes, purchases, rebooting, or deleting photos, and keep the phone agent tasks narrow as the skill directs.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • 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

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
75% confidence
Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

## Do not

- Do not call `start-rental-tool` or `request-phones-tool`. Those spend the user's money.
- Do not use `reboot` or `clear_photos` without asking. One interrupts anything running,
  the other deletes the camera roll.
- Do not type passwords or codes into a phone unless the user gave them for that purpose in
  this conversation.
