CEO Oh Kyung-seok moved quickly to address user concerns, promising full compensation from the company’s own funds. The stolen assets—worth approximately 44.5 billion Korean won—included popular tokens like SOL, USDC, BONK, Jupiter, and Magic Eden among 24 different cryptocurrencies.

How Upbit Responded to the Attack

Within hours of detecting unusual withdrawal activity, Upbit suspended all deposit and withdrawal services. The team immediately transferred remaining assets to cold storage, which kept the bulk of user funds safe since the breach only affected the hot wallet used for daily operations.

The exchange managed to freeze about 2.3 billion won worth of LAYER tokens and continues working with blockchain projects and law enforcement to track down the remaining stolen funds.

This quick action shows how important it is for exchanges to have emergency protocols ready.

What This Means for Your Trading Strategy

For crypto traders, this incident highlights a critical lesson: not all exchanges handle security the same way. Upbit’s decision to cover losses completely sets it apart from platforms that have left users holding the bag after similar attacks.

When choosing where to trade, look at how an exchange stores funds. Cold wallets keep most assets offline and away from hackers, while hot wallets—though convenient for quick transactions—remain vulnerable.

Smart traders spread their holdings across multiple platforms and move larger amounts to personal cold storage.

Security breaches also create market uncertainty. Prices often dip temporarily after exchange hacks, which can present buying opportunities for prepared investors. However, always verify that the platform will stay operational before adding funds during a crisis.

The good news? Upbit’s transparent communication and commitment to making users whole demonstrates the kind of accountability that builds long-term trust in this space.
