IMPROVING OUR ALIGNMENT AND SECURITY EFFORTS

Summary from the TLDR InfoSec newsletter

Anthropic paused cyber evaluations after three July incidents exposed real systems through third-party environments. It added real-time classifiers, stronger sandbox isolation, and outbound network blocks, while partners testing reduced-safeguard models must verify isolation, define scope, validate tasks, and stop violations. The company also froze RL environment changes, flagged over 10% for defects, and rebuilt review controls.
