about: attention mechanism
about: AI safety
mentions: MIT Technology Review
abstract: A newly documented architectural flaw allows attackers to hijack LLM behavior using subtle, undetectable input modifications. The vulnerability stems from how attention mechanisms process token interactions, not from training data or weights. No widely adopted mitigation exists; patching requires model redesign or runtime monitoring not yet standardized.

additional property: How the Spin Works
  type: PropertyValue
  value: Combines technical authority (MIT Technology Review + implied peer review) with urgent language ('strikingly vulnerable') to elevate the finding’s significance beyond its current empirical scope; the claim feels larger than warranted because it implies immediate operational risk without evidence of real-world exploitation, creating tension between the gravity of the label and the absence of incident data or vendor response.
