pikpak-onboarding

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed PikPak onboarding guide with a small offline command previewer and no evidence of hidden execution, credential collection, persistence, or exfiltration.

Before using it, read the referral disclosure and only accept the invitation code if you want to. Treat generated commands as a preview: run PikPak account, registration, or task commands only after confirming the current account and the link/content you provide are yours to use.

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
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • 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
Findings (3)

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
84% confidence
Finding

The skill explicitly states it reads a bundled config.json, which means it requires file-read capability, but it does not declare a restrictive tool scope such as permissions or allowed-tools. Without an explicit scope, a host may grant broader file access than intended, weakening least-privilege guarantees and making policy enforcement dependent on external host behavior.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
90% confidence
Finding

This markdown file contains operational guidance only in Chinese, which can effectively force a specific language on users or maintainers. Under the policy, language constraints should be opt-in or clearly justified as locale-specific.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

This code emits user-facing natural-language strings only in Chinese, which can force a specific language/locale on users without opt-in. The policy allows locale constraints when documented and justified, but no such justification or language choice appears in this file.
