- 4Simon Willison·7/22/2026securityThomas Ptacek on sandbox escapes and open-weight models
Simon Willison quotes Thomas Ptacek arguing that a 2025 open-weights model, if paired with a pentest harness, could likely perform sandbox escapes and scan or attack many networks. The remark suggests the surprising part is not the capability itself, but the assumption that OpenAI’s sandboxes are sufficiently robust.
