Monero Profitability Calculator

Security checks for vulnerabilities and agentic risk

Overview

This is a simple Monero profitability calculator skill with a disclosed live price lookup and no evidence of hidden persistence, credential use, destructive actions, or exfiltration.

Before installing, treat this as an informational calculator rather than a complete CLI tool. If you run the example Python code, it will contact CoinGecko to retrieve public Monero price data, so avoid adding secrets or private data to the request. The voluntary XMR tip address is disclosed and not automatic.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

External Transmission

Medium

Data Exfiltration
Confidence
50% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
87% confidence
Finding

This markdown file includes a Python example that fetches Monero pricing data from an external API using requests.get. The surrounding skill description does not explicitly warn users that using the example involves outbound network access and transmission of request metadata to a third-party service.

Context-Inappropriate Capability

Low
Category
Not specified by scanner
Confidence
87% confidence
Finding

The skill is presented as a simple Monero mining profitability calculator, which primarily implies local arithmetic over user-provided inputs. The embedded example script performs an external HTTP request to CoinGecko to fetch live market data, a capability not otherwise justified by the unknown/unstated manifest scope and broader than a purely local calculator.
