Nobody needs Mythos or 0-days to build a chaos-causing computer worm – free open source models work just fine

'Attackers can now cheaply operationalize known vulnerabilities at scale,' boffins tell The Reg

Why this matters
Why now

The proliferation of advanced open-source AI models and readily available vulnerability information makes sophisticated cyberattacks executable without exceptional resources or knowledge.

Why it’s important

This development democratizes the creation of potent cyber weapons, enabling a wider range of threat actors to launch widespread disruptive attacks against critical infrastructure and data.

What changes

The barrier to entry for developing and deploying chaos-causing computer worms is significantly lowered, increasing the risk of systemic cyber disruptions for governments and corporations globally.

Winners
  • · Cybersecurity defense firms
  • · Insurance companies specializing in cyber risk
  • · Nations with robust cyber defense capabilities
Losers
  • · Companies with weak cybersecurity postures
  • · Critical infrastructure sectors (e.g., energy, finance)
  • · Small and medium enterprises (SMEs)
Second-order effects
Direct

Increased frequency and severity of cyberattacks, particularly those leveraging AI for scalability.

Second

Governments and industries will be forced to accelerate investment in advanced cybersecurity measures and AI-driven defense systems.

Third

Potential for cyber-induced economic instability or geopolitical tensions as state and non-state actors exploit these new capabilities.
