At the moment the depositing/withdrawing of cryptocurrencies is blocked. All assets, according to the exchange, are transferred to cold wallets. Upbit will indemnify all clients’ losses in full.
The MyCrypto service also found large transfers of TRX tokens from Upbit.
Apparently Upbit is confirming hack. Here’s our thought process and some links when we looked a few hours ago for those looking now

Some observers are sure that an insider worked among the exchange employees since the attack was carried out at the moment when the exchange was moving funds.
The “hacker” timed when UPbit was making crypto transfers to its cold wallet (other alts like TRON, etc.)
Hence, I think the probability of it being an inside job is higher than external breach.
No details are certain for now. Will continue to update.https://t.co/Yv01WYvPok

The international community believes that North Korea is involved in attacks on the South Korean business.
