Threshold Says tBTC Operators Patched or Went Offline Over Linux Flaw

The detail that matters here is operational rather than technical: Threshold is describing a node population that either patched or dropped out, which means tBTC's liveness depended on how quickly a distributed set of operators responded to a Linux flaw. The separate drain of roughly 0.5 ETH from a fee-paying account is small in size but sits awkwardly next to that disclosure, since it points to operator-side exposure rather than the bridge itself. With about $136.3 million of tBTC sitting in Aave's frozen Ethereum Core reserve, whether operator participation holds steady and whether the fee-account incident is isolated are the open questions.
