Nobody needs Mythos or 0-days to build a chaos-causing computer worm – free open source models work just fine
⚡ TL;DR · AI summary

Researchers from the University of Toronto have demonstrated that free open-source AI models can be used to create computer worms that exploit known vulnerabilities. Their prototype worm adapts to target systems and spreads through networks without relying on zero-day vulnerabilities. This highlights a significant security threat as attackers can operationalize known vulnerabilities at scale, potentially outpacing defenders' ability to respond.
