Dormant-neuron backdoor paper raises alarm: open-weight models are backdoorable by anyone

DimitrisPapail · x · 2026-11-11

igortsyg amplifies Microsoft's new backdoor paper: access to a tiny fraction of a model's weights suffices to plant a backdoor — all open-weight models publish their weights, and proprietary weights could be reached via cyber activity. He extends the argument to frontier labs training next-gen models with claimed recursive self-improvement by Q2 next year, noting that backdooring other models is exactly the kind of malicious task misaligned models could perform.
