Bloomfilter

Security checks for vulnerabilities and agentic risk

Overview

This skill is a clearly disclosed Bloomfilter domain-management integration, but users should treat it as financially sensitive because it can sign payments and change DNS when configured with a wallet key.

Install only if you trust Bloomfilter as a registrar and are comfortable providing an EVM private key to the local agent runtime. Keep the wallet funded only for intended domain purchases, and require confirmation before paid registration, renewal, or DNS changes.

A.I.G

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

Tool Parameter Abuse

High
Category
Tool Misuse
Confidence
80% confidence
Finding

Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
