Security audit

Adyntel

Security checks for vulnerabilities and agentic risk

Overview

The Adyntel features match the stated purpose, but setup directs the agent to execute a remote installer without a clear approval or verification step.

Review and approve CLI installation separately before enabling this skill, preferably using a pinned release with authenticated integrity verification. Expect Adyntel queries and account access to pass through OOMOL. The remote installers were unavailable for inspection, so their system changes remain uncertain; no malicious behavior was established in the bundled artifact.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output

Findings (5)

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
99% confidence
Finding

The supplied code installs remote software instead of searching or reading Adyntel data. Nothing in the chunk establishes this installation as a supporting dependency for Adyntel functionality. The downloaded script's contents and further effects are not shown.

No source excerpt is available for this finding.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
92% confidence
Finding

The supplied chunk performs only a login operation; it contains no Adyntel search or read behavior. Authentication could be a supporting implementation detail if the CLI were established as an Adyntel client, but the supplied content provides no such connection.

External Script Fetching

High
Category
Supply Chain
Confidence
99% confidence
Finding

Piping an HTTPS response directly into bash executes mutable remote content without a pinned version, signature check, or opportunity to inspect the complete script first. A compromised installer endpoint could therefore execute arbitrary commands under the agent's local account; this is the same underlying installation risk identified by SQP-2, not a separate exploit chain.

Fallback setup executes downloaded installation scripts without warning about system changes or remote-code execution.

Medium
Category
Output Handling
Confidence
97% confidence
Finding

The fallback directs the agent to execute downloaded shell or PowerShell code without an explicit installation approval step or integrity verification. If the installer source or delivery infrastructure is compromised, that code could access local files and credentials or modify the system with the invoking user's privileges; the missing-CLI condition limits exposure but does not remove the 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.
