MachFive Cold Email
Security checks for vulnerabilities and agentic risk
Overview
This skill is a coherent MachFive API guide for building cold-email campaigns and generating email sequences, with costs and external data use disclosed.
Before installing, confirm you intend to use MachFive for outbound email generation and are comfortable sharing lead data and sender signatures with that service. Review credit costs before approving previews or generation, especially enrichment and batches, and use notification emails or polling only for jobs you actually want completed.
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
