What happened
On November 27, 2025, Upbit reported about $36M in unauthorised outflows from a production Solana hot wallet and suspended Solana rails.
The outflows hit multiple Solana assets, and the important operational point was that Upbit said cold wallets were not compromised and customer balances would be made whole. That suggests an exchange hot-wallet security failure rather than a total infrastructure collapse. Still, when a major exchange says unauthorised outflow, the words are polite but the meaning is not.
