MikroTrick Chain Let Attackers Take Over MikroTik Routers Without a Password or SSH Key

What Happened

Two MikroTik RouterOS SSH vulnerabilities chained together let attackers take full administrative control of Internet-exposed routers without a password, SSH key, or completed authentication. The chain, which CERT Polska calls MikroTrick, combines an SSH state-machine flaw (CVE-2026-67279) with an argument-injection bug in the RouterOS login process (CVE-2026-86060). Attack logs date to at

Why It Matters

The report describes the MikroTrick chain, in which two MikroTik RouterOS SSH vulnerabilities enabled unauthenticated attackers to obtain administrative control of Internet-exposed routers. This is a conventional network-device vulnerability and does not directly involve artificial intelligence, AI agents, models, or AI services. Under the required fallback classification, it is mapped to AI agent abuse and the listed RealGround services; that mapping is an administrative fallback rather than a claim that the incident is AI-related.

RealGround Analysis

This signal maps to AI agent abuse. Organizations using AI agents, LLM APIs, SaaS integrations, or sensitive data workflows should review whether this class of issue could create unauthorized tool execution, data leakage, weak approval gates, or unmanaged supply-chain exposure.

Recommended Actions

  • Restrict AI agent tool permissions and production write paths.
  • Review sensitive data access across prompts, logs, embeddings, memory, and SaaS integrations.
  • Add human approval workflows for high-impact or state-changing actions.
  • Run prompt injection and indirect prompt injection tests against affected workflows.
  • Document the owner, control gap, and remediation deadline for this risk class.
