Outtake Bounty Network

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed helper for registering with and submitting malicious-domain bounty reports to Outtake, with no hidden execution or persistence found.

Install only if you intend to use Outtake's bounty program. Registration and submissions send your email, wallet address, submitted domains, evidence notes, and discovery method to Outtake, and the OUTTAKE_API_KEY should be treated as a secret.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

External Transmission

Medium
Category
Data Exfiltration
Confidence
60% confidence
Finding

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

Autonomous Decision Making

Medium
Category
Excessive Agency
Confidence
75% 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.

# Outtake Bounty Network

Earn $5 USDC per verified novel malicious domain. Discover phishing, scam, impersonation, malware, and prompt-injection domains targeting real companies or AI agents — get paid for each verified novel find. No approval needed. Register, then submit only independently discovered domains that are not already public.

Beta: capped at 200 paid approvals. New submissions are rejected once the cap is reached.

## How It Works

1. **Register** — `POST /register` (no approval needed)
2. **Discover** — Find novel malicious domains targeting real companies
3. **Submit** — `POST /submit` with URL + evidence + `discovery_method` for an independently discovered novel threat
4. **Verification** — Outtake reviews automatically + manually

Whitespace Padding

Medium
Category
Prompt Injection
Confidence
70% confidence
Finding

Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.
