Lost Wallet Lockdown

Security checks for vulnerabilities and agentic risk

Overview

This is a prompt-only lost-wallet checklist skill that stays within official-channel planning and avoids credentials or automated actions.

Reasonable to install. When using it, keep using placeholders and do not share full card numbers, PINs, CVV codes, passwords, one-time codes, full SSNs, or unredacted ID images; verify contact paths through official apps, statements, agency sites, or in-person offices, and use emergency services or local authorities if there is immediate danger or home-security risk.

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

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
93% confidence
Finding

The file requires skill.json to declare language=en, which imposes a specific language setting. Because no opt-in or rationale is provided here, this appears to violate the policy against forcing a language or locale without user choice.

Natural-Language Policy Violations

Confidence
95% confidence
Finding

The acceptance criteria explicitly require public-facing documentation to be English only. This is a natural-language locale policy constraint, and the file does not present it as optional, user-selected, or justified by a region-specific purpose.

Finding

The manifest sets "language": "en", which imposes a specific language/locale choice. Under the policy, language restrictions should either be optional for the user or clearly justified as region-specific; no such opt-in or justification appears in this file.
