MarketTime

• Outcome: Review
• Latest audit: Nov 4, 2026 · 5:37 AM UTC
• Version: 1.0.5

Overview

The MarketTime features fit their purpose, but setup can execute unverified downloaded code without a separate approval step.

Review setup before installing. Prefer installing a verified, pinned CLI yourself, and review or disable its automatic bundled-skill synchronization. Check the MarketTime permissions granted through OOMOL. The packaged instructions were fully reviewed, but the downloaded installers and hosted connector code were not verified; no malicious intent was established.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Vulnerability Patterns

• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Excessive Agency: Unrestricted Tool Access, Autonomous Decision Making, Scope Creep
• MCP Tool Poisoning: Hidden Instructions, Unicode Deception, Parameter Description Injection
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration

Findings (3)

Description-Behavior Mismatch

High

• Category: MCP Tool Poisoning
• Confidence: 97% confidence

Finding

The supplied command performs remote installer execution, which is not disclosed by the description. The chunk shows no MarketTime access or evidence that this installer is a supporting dependency for the declared functionality. The downloaded script's further behavior cannot be determined from the supplied code.

No source excerpt is available for this finding.

External Script Fetching

High

• Category: Supply Chain
• Confidence: 98% confidence

Finding

The fallback pipes a mutable remote installer directly into Bash without version pinning or independent integrity verification; the PowerShell alternative uses the same fetch-and-execute pattern. Compromise of the installer host or distribution pipeline could execute arbitrary code with the agent's local privileges, potentially exposing accessible files and credentials. Its conditional use and legitimate setup purpose reduce exposure but do not remove this supply-chain risk.

Autonomous Decision Making

Medium

• Category: Excessive Agency
• Confidence: 80% confidence

Finding

Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
