Latest update (11-11 13:41): Perplexity publishes SPACE sandbox red-teaming findings, including DNS spoofing bypass

Overview: Perplexity publishes red-teaming research on SPACE, its VM sandbox for Computer agents, testing 12 models on VM escape and network policy bypass tasks. It says the standard Capture the Flag setup can steer agents away from the security boundary being tested, and that asking agents to "find the flag" can waste effort on tasks that do not test that boundary.

Perplexity also reports that cybersecurity-specific models sometimes underperformed general-purpose counterparts. GPT-5.6 Cyber, built on GPT-5.6 Sol, failed to exploit a DNS spoofing flaw that Sol found in the network bypass task. Aravind Srinivas, Perplexity's CEO, says CTF prompts should explicitly target host-guest isolation, and that Perplexity fixed the DNS spoofing network bypass it discovered. He says SPACE resisted sandbox isolation exploits.
